⚠️ CONTENT WARNINGS:
This story includes heavy Dark Monster Romance, lots of blood and violence, intense sensory details, explicit/intimate tension, and a lot of jokes and media references (bringing back that good old JJK Season 1 vibe! Yay!).
📖 AUTHOR'S NOTE (Please Read):
Before we dive into the Skandha, I want to clarify a quick lore detail regarding my writing.
I am using actual logic and realism for this story. For example: in this fic, Dagon knows exactly how Domains (complete, incomplete, and open-barrier) and Binding Vows work.
How does he know? Simple. He literally lived for months with Suguru Geto/Kenjaku (the mastermind behind the Culling Games) and his three Disaster siblings—who ALL have Domain Expansions. It is completely unrealistic to think that a curse living with thousand-year-old combat veterans wouldn't have learned from them. Canon Dagon may have been an "introverted" cursed womb for a while, but he wasn't an idiot.
P.S. This story is 100% human-written, fueled by pure spite for Gege's writing and a massive, unhinged crush on a sea monster. Italian is my first language, so I use grammar checkers and translators to make sure my English is readable, but the plot, the lore, and my absolute obsession with Dagon's wet abs? That's 100% my own human brainrot. AI could never write tentacles and abyssal devotion this well anyway. Enjoy the meal! 🐙🌌✨
Okay, now it starts, and remember, this is WIP and WILL change in AO3!
Chapter 1: The Reunion Between the Cosmos and the Abyss
In the deepest depths of the cosmos, where galaxies rest in eternal silence, there was a small kitsune. His name is Kasari: the ethereal beauty of space, but also the living terror of the abyss that was the universe itself. Kasari is as old as creation. Being the ultimate terror of deep space, he is infinitely more powerful than any cursed spirit ever seen before; an entity capable of surpassing even Sukuna if the two were ever to clash.
He is usually calm and patient, but he harbors a madness that rarely explodes within him. In all the millennia he has lived, he has known everything about the world. He has watched entire civilizations be born and disappear, solar systems form and collapse, stars ignite and explode. Kasari Inuzumaki is as old as the universe.
And yet, Kasari has lived Yuji's story, silently watching the boy's entire journey: the tragic loss of Junpei—whom Kasari secretly brought back to life—the brutal battle against Choso's two brothers, and even Yuji's very first fight against the bearer of Sukuna's finger, all the way up until the nightmare of Shibuya.
In Shibuya, Kasari watched Hanami's death. Right before the curse of forests and nature could disappear completely into the void, Kasari secretly took her cursed energy, storing her soul safely away. Then, he felt it. A powerful cursed energy, heavy, terrifying, yet fused with a heartbreaking rage and hatred. He reached Shibuya station, where he found Dagon, who had just evolved.
Kasari hid himself in the shadows, watching Nanami, Maki, and Naobito ruthlessly attack Dagon. The humans seemed to have the upper hand, especially Naobito, but Dagon was stronger than all of them put together. Even while immobilized by the old man, Dagon tore open a seal of cursed energy from his own abdomen, instantly expanding his domain.
Maki, Naobito, and Nanami found themselves on a beach, breathtakingly beautiful and serene, while Dagon hovered over the sea on the opposite side.
“Domain Expansion: Horizon of the Captivating Skandha.”
Dagon summoned an infinite wave of Shikigami; these weren't just little fish, but sea monsters crawling straight out of the worst Lovecraftian nightmares. After just a few minutes, Nanami, Maki, and Naobito were drowning in difficulty. Dagon was highly intelligent, perfectly calculating how to split the effect of his Death Swarm between Nanami and Naobito who, compared to Maki, were the ones capable of dealing serious damage.
And then, Megumi arrived, piercing the barrier with his incomplete domain.
“Is that insignificant human polluting my domain with his uproar..?” Dagon thought. “His domain… it doesn’t have a barrier… I’ve heard of domains like that… it’s not like Sukuna’s… it’s incomplete, so why is it able to hold its own against mine? Could it be a binding vow? Dammit, it’s all so complicated, I… I just want to avenge Hanami… I just want to live with my family!”
Besides the pain, the fury, and the hatred consuming his mind, Dagon was feeling something else… sadness? Or something like it?
But… then another figure appeared.
The air of the beach was fresh and serene. The tropical sun warmed Kasari’s pristine white fur as he stood effortlessly on the surface of the water. He should have sunk into the abyss of the Skandha, but he was simply operating on a superior level: in cursed energy, in combat, in his cursed technique.
But all Kasari could focus on was that giant red octopus on the white sand, near those beautiful palm trees dancing with the light sea breeze. He could feel the tragic rage that was stealing Dagon's emotions.
Nanami, Maki, and Naobito were completely shocked. Even Megumi, who was desperately trying to open a gap in the barrier, stopped for a second. Kasari's entrance had stolen all the attention in the world.
Maki looked at him, her eyes wide. "You... are the fox? But they said you were dead!" She stared at Kasari's clothes, the red scarf, the deep blue mantle moving with living constellations. "So it really is you." She gripped the Playful Cloud tightly, her only cursed tool at the moment. Without it, she was prey for the strongest.
Naobito didn't hesitate. He tried to approach Kasari with a dash; his 24-frame projection technique made him almost imperceptible through movement alone. But... Kasari had already seen everything. He saw the water splitting in half under Naobito's invisible body, felt the violent air that seemed like it could blow him away at any moment...
And then, Naobito was there, right behind Kasari. He had him in his grasp. The old man would not leave any curse alive, not even one with such a mystical aura and a presence that felt almost human.
Nothing... no sound, no movement. There was no way to predict it.
"What the f*ck?" Naobito blurted out instantly, his eyes wide with surprise and shock.
"You are already dead."
Kasari was already behind Naobito. He hadn't teleported; it was just his pure, god-like speed. Megumi, Maki, and Nanami watched the scene, paralyzed.
“What extraordinary speed, I couldn't even see him... he's faster than Naobito!” Nanami thought in surprise, a heavy dread creeping into his chest for this new threat.
“He's faster than Sukuna... he's stronger than... D-Dagon!” Megumi said to himself with the grim expression of someone who had lost all hope. Still, he desperately tried again to open the gap in secret.
Maki, clutching the Playful Cloud, looked at Dagon, who was distracted by Kasari's intervention.
"Who... are you?" Dagon’s voice was cavernous, a deep, tectonic rumble that sounded almost like a sigh of the sea. He moved to go towards Kasari.
"But, I will be kind to you," Kasari said coldly, ignoring Dagon for a second to look at Naobito while strangling him by the neck. The grip was crushing. Naobito, a Special Grade sorcerer, known as one of the fastest men on earth, was suffocating helplessly against a threat that had appeared out of nowhere.
"You will decide how you will die, old man. You just have to choose a card."
Time seemed to dilate, freezing for a millisecond. With the deck of cards in his other hand, Kasari began to prepare them, shuffling them to make reality as random as possible. Four ethereal cards made of stardust floated in front of him.
"Oh, you're lucky. You drew The Supernova."
With brutal force, Kasari hurled Naobito high into the air. "Are you ready, old man? If you survive this, I'll give you credit."
He took a running start. Splash-splash. Kasari's paws touched the crystal-clear, shimmering water with every hurried movement, and then, with a tremendous leap, he jumped into the air. The serene blue sky of Dagon's Skandha contrasted beautifully with Kasari's fur, which looked almost like a fluffy cloud on the horizon.
Kasari closed his left hand, pulling his arm back. After a second, his fist was flying at full speed toward Naobito's abdomen. The cursed energy on Kasari's fist ignited in a time frame of 0.00001 seconds.
A violent distortion cracked the air upon impact. A dark black and a bright red burst from the collision, spreading out in a shape that resembled a jagged electric shock. The two colors painted Dagon's sky, the red expanding with the black, covering a vast portion of the horizon.
"Black Flash!"
Kasari formulated the sentence, calling out the universal jujutsu technique. It was a rare, devastating move impossible to do on command for normal sorcerers. The sheer force sent Naobito's broken body bouncing away until he crashed violently against a rock, bleeding and suffering.
Dagon, with his glowing yellow eyes, watched the scene. The sky painted in red and black, Naobito's blood flowing toward the sand and polluting the crystal-clear, shimmering water of his domain.
Kasari fell down with elegance, using his two tails in a propeller-like movement to descend gently.
"You, you are next," Kasari said, looking at Dagon.
Dagon took steps back, trembling from Kasari's aura alone. The Kitsune's ancient, stellar cursed energy seemed to almost absorb Dagon's aquatic energy.
"Y-you... you are different!" the guttural sound of Dagon's cavernous voice erupted in Kasari's ears.
"Different? What do you mean by different?" Kasari approached, his arms and hands intertwined casually behind his back. "My cursed energy? My appearance? Or perhaps something more? Perhaps, you being a Special Grade curse can perceive my difference from you?"
Dagon took another step back to create distance. The air turned almost hot with the heavy tension between the two. However, Dagon suddenly found himself with his back against one of the palm trees of the Skandha. He could no longer back away.
Kasari looked at Dagon, from the tips of his feet to his head.
How... cute he is in this moment... Kasari thought. Such a mighty creature, with these bulging muscles, fearing an innocent fox like me... it is poetry.
But Kasari's thought immediately contradicted itself. What is this feeling? A crush...? For that octopus... why now? Why specifically him? After all these years I have never felt anything like this. What are you doing to me, little octopus?
Dagon looked at him, his breathing becoming heavy and labored from the tension. This one... he could kill me. What are you waiting for, Dagon... you must live, so you can protect Jogo and Mahito... he thought to himself. But he was completely immobilized by Kasari's almost crazed, lustful gaze.
"You... you are making me explode with emotions!" Kasari said, with a sudden lunge that brought him dangerously close to Dagon's imposing chest. "But why you of all people? Among all those who are stronger than you? Why you? You who might not even be worthy of a God of Chaos like me?"
His two tails intertwined intimately around Dagon's rock-hard black abdomen to hold him tight. "What is special about you? Tell me, what are you doing to me? What is this sensation? A secret technique of yours? Out with it!... or out with the fish, in this case..."
Kasari seemed to have gone mad, a maniacal smile spreading across his muzzle. He was madness made flesh. Dagon looked at him in disbelief. All of this was wrong. This... curse... what on earth was he blathering about? Since when does a curse feel these sentiments?
"I...? I have a name, and it is Dagon! I have emotions! Jogo, Mahito, Hanami, we all have our reasons!" Dagon yelled defensively. "Who are you to tell us what we are?!"
But Kasari wasn't listening. His mind had completely short-circuited. What did he just say? Kasari thought, his orange eyes glued to the thick saltwater sliding down Dagon's sculpted pecs and dripping onto his obsidian-black 8-pack. I didn't hear a damn word... Those wet muscles... it’s flawless perfection.
"You are human!" Dagon snapped back, forcefully pushing Kasari away.
Kasari, pushed into mid-air, did a graceful backward flip and landed safely on both paws.
"Bingo! But, you were half-wrong... you see, I am... both!" Kasari pointed a finger at his own chest. "I have the body of a curse, but I also have a human heart! And you lack one, don't you? I heard you crying before this domain!"
He approached Dagon again, their faces very close, Kasari's muzzle almost brushing against Dagon's thick facial tentacles. "Are your emotions real? Do you believe you can love like a human? Do you truly believe that curses can replace them without the one thing that would make you more human than them?"
Maki, Nanami, and Megumi watched the scene, the shock heavier than ever. Naobito was bleeding out on a rock, while Dagon and Kasari had a bizarre, incredibly tense chemistry.
Nanami commented first: "I didn't leave my desk job at the company for... for this!" He gestured toward the two lovebirds, while Megumi was desperately focusing on keeping the gap open and widening it.
"I'm almost there..." Megumi's voice was low; he couldn't let himself be heard by Dagon and Kasari, but he had to warn his comrades.
Maki, who had always seen curses purely as monsters, watched the scene with disgust. "Damn, not only do the weak ones stay in groups, but now even the strongest are teaming up? There are more of us, but they are on another level, especially that fox!" She gripped the Playful Cloud tighter, the hold almost hurting her hands.
Dagon looked at Kasari and pushed him away again. "Just because you laid out a weakling doesn't mean you'll lay me out too." However, his last words weren't very convincing.
Kasari laughed, a gentle, almost smug sound. "Then it's true! Even a monster can have feelings!" Then, his gaze turned incredibly dark and serious. "But now, the real question is: who is the monster between you and me?"
Kasari drew the sword of constellations: The Knight, and attacked. Dagon dodged the first blow, immediately summoning a Shikigami to annihilate the fox, but Kasari destroyed it effortlessly with the blade.
Dagon tried to create distance, moving backward with leaps and summons, but the more he summoned, the more exhausted he felt. Dammit! Keeping the domain open, facing 5 people at once… and trying to maintain dominance over the domain, all because of that black-haired brat with the shikigami! If it weren't for him, this fox would be dead already!
And then came an unexpected blow. With a swift motion, Kasari slashed Dagon from his abdomen to his chest. It was a sharp, clean cut that sprayed vibrant purple blood onto Kasari and the white sand.
Kasari stopped for a second, looking down at his own hands covered in the warm, purple liquid. It felt as if the blood were branding him. What warmth… what beauty… his blood… it’s so purple, so… pure…!
Kasari's mind wandered into a crazed euphoria. He set his glowing eyes on Dagon with the terrifying smile of a madman about to do something unspeakable.
“I will kill you!” Kasari said, his maniacal laugh giving Dagon the terrifying creeps.
S-shit! What the hell is wrong with him!? Dagon thought, panicking. I have to stay away, or he’ll kill me…
Dagon's thought didn't even have time to fully form before Kasari was already in front of him, ready to strike again. But just as Kasari raised his blade to claim Dagon's soul, Megumi gasped and lunged backward, drawing everyone's attention.
And it was at that exact moment. The man with black hair and those dead, black eyes from Ogami's séance... Toji Fushiguro had returned from death to bring destruction in his path.
A deep silence fell over the horizon of the Captivating Skandha. Toji stepped through the very hole Megumi had opened, making his son back away. Megumi looked at him with a serious gaze: did he recognize him?
Maki looked at Toji, and the Sorcerer Killer, with superhuman speed and agility, snatched the Playful Cloud straight from Maki's hands, pushing her aside effortlessly. Nanami, surprised by Toji's attack, backed away as well, calculating the axis between 3 and 7 for a weak point; anything to ensure fewer opponents to face so he could maybe, finally, return to his desk job.
Naobito had definitely lost consciousness on the rock.
No cursed energy... Dagon thought, looking at Toji. Maybe he’s less worse than this sticky ball.
Famous last words. Toji, with speed enough to split the sea, struck Dagon's skull with the Playful Cloud, catching the giant curse completely off guard and sending him tumbling through mid-air.
Kasari, no longer feeling Dagon's warm presence in front of him, slowly turned his head to look at Toji. His orange eyes flared a blinding, furious red.
"Who is this asshole?!" Kasari roared. "Interrupting me while I was about to snuggle with my octopus! He is mine alone, how dare you touch him!"
But Toji ignored him. He relentlessly pursued Dagon, beating the Abyssal King with the Playful Cloud. Every movement was terrifyingly agile, faster than Dagon, who relied heavily on physical endurance.
Dammit, Dagon thought, taking brutal hits. If only that brat would run out of cursed energy reserves, if only I could force him to close his domain, mine could kill this human!
But as the thought formed, Dagon found himself exhausted on the beach. The armor on his left shoulder had been bypassed, two deep cuts revealing his purple essence. Toji looked at him with a maniacal, devilish gaze, sharpening the two remaining sections of the Playful Cloud to deliver the final blows.
Shit, I need to stall for time, Dagon thought frantically. Jogo will arrive and save me from this shitty situation. With a high leap, he unfolded the small wings at his pelvis, ready to fly away to reposition.
Suddenly, the shapes of the 24 frames of the Projection Technique flickered. Naobito, with a last burst of energy, delivered a sharp blow that knocked Dagon back down. Toji took the advantage, leaping into the air and latching onto Dagon, preparing to thrust the sharpened rod straight into Dagon's forehead.
"I-It's not over yet!" Dagon screamed. But Toji, pitilessly, launched the fatal blow...
Or... so it seemed.
"How dare YOU?!" a voice of unadulterated, cosmic rage shattered the silence. "To touch what I have reclaimed! What is mine by right!"
"Stellar Spark!"
Kasari held up a single stardust card in front of him, using it as a cosmic prism. An explosive flash of concentrated, blinding starlight blasted through the card and struck Toji point-blank. It didn't disintegrate him, but the sheer kinetic force sent him flying straight out of the entire domain, blasting him through the hole that closed instantly behind him.
Dagon fell heavily to the ground, bleeding and gasping for air. Kasari approached him, kneeling softly on the sand. He took Dagon by one of his thick tentacles and, with his muzzle, sought out the hidden mouth beneath them.
Kasari pulled him into a kiss full of feral possessiveness, but layered with a true, indisputable, and profound love.
Nanami watched the scene, utterly done with this day. “Dammit, Megumi, the gap!” he commanded Megumi, who was holding the opening with all his might. Maki and Nanami exited the domain in a rush, leaving the two anomalies behind.
Kasari's lips met Dagon's beneath the tentacles; their tongues intertwined, holding on to each other as if their lives depended on it. Dagon instinctively placed an enormous hand behind Kasari's neck to hold him close. His tentacles explored the fox's soft face, which was somehow conquering the terrifying King of the Sea inch by inch.
“Mine. And no one else will ever touch you again,” Kasari exclaimed, his breath heavy and hot after the kiss.
Dagon looked at him, his yellow eyes full of conflicting emotions. This... human... he saved me and is kissing me... Why don't you kill me? Is this what you feel for me..? Me, a curse, a monster in your eyes... and you look at me as if I were the most precious thing in the universe...
Naobito, who was bleeding out nearby, looked at the closing gap. I-I can escape now... he thought, trying to use his technique to flee.
But suddenly, Kasari grabbed him by the collar and yanked him back violently. “And where do you think you're going? You dared to make him cry. For that, I will make you suffer.”
Without a shred of hesitation, Kasari impaled him with the Knight's sword. The blade of constellations pierced the old man instantly, his human flesh useless against a weapon capable of cutting through reality itself. Only Naobito's scream of pain shattered the silence. Dagon watched the scene from the sand, a deep sense of satisfaction warming his chest. Finally, the old man was getting exactly what he deserved.
But then, abruptly, Dagon's domain crumbled to pieces. It wasn't natural; it was destroyed by an external attack.
Flames had completely infested Shibuya station. Dagon and Kasari stood in the center of the blazing ruins. Naobito, Megumi, Nanami, and Maki hadn't even had time to escape before a volcanic form burned them one by one without mercy. Naobito was charred alive. Maki had a chance to survive, but Nanami was left on the verge of death.
Jogo, the living flame that had scorched the sorcerers, turned toward Dagon and Kasari.
“Dagon… you are no longer a cursed womb?” Jogo asked, his initial surprise quickly morphing into curiosity, and then, profound irritation.
“Who the hell is that? And why do you let yourself be held by his tails?” Jogo snapped, pointing an accusing finger at Kasari's twin tails, which were possessively wrapped tight around Dagon's abdomen.
Dagon, feeling a spike of fear, didn't know how to answer. How could he justify himself? This half-human saved my life? Jogo wouldn't accept those excuses. Jogo only accepts facts, and Kasari would have to prove himself worthy before the flames of the volcano that was about to erupt.
Kasari stared blankly at Jogo. The volcano was infuriated, glaring at the fox with utter disgust. But Kasari simply ignored him, resting his face gently against Dagon's chest.
“So your name is Dagon?” Kasari whispered. He tested the name on his tongue, and the sound of it made him go even crazier. He drew closer, his fox muzzle pressing intimately against Dagon's warm cheek.
“You are beautiful, Dagon,” Kasari said. His voice was soft, meant only for Dagon’s ears, while Jogo heard nothing beyond the furious roaring of his own flames.
“What the hell are you blathering about?!” Jogo screamed at Kasari, who continued to completely ignore his existence.
Dagon, overwhelmed by all the intense attention Kasari was giving him, and embarrassed by Jogo's angry presence, felt a deep heat rise to his face, marking his red skin with an even deeper flush.
“S-Stop it… both of you…” Dagon stammered, trying to gently push Kasari away and regain control of the situation. But Jogo wasn't listening, and Kasari was entirely too lost in admiring his husband's body.
Kasari ran his hands shamelessly over Dagon's sculpted pecs, tracing the muscles that were still slick and wet after the clash in the Skandha. They drew closer together involuntarily, Dagon losing himself in the touch as well.
Jogo was furious. The volcano erupted, fire exploding in avalanches like an infernal flamethrower. “Stop ignoring me! Dagon, get out of the way!”
Kasari's ear twitched at Jogo's loud voice. With agonizing slowness, he turned his head toward Jogo.
I was preparing dinner and this shitty volcano burned it for me, Kasari thought, glancing at Naobito’s charred corpse.
“Oi, you shitty volcano. First you ruin the meal I was preparing for my love,” Kasari said, gesturing lazily toward the burnt sorcerer.
Dagon looked at Kasari, his eyes wide. This guy is crazy… I only ate humans to power myself up when I was a cursed womb… but he wanted to cook one alive for me… to show me his love… No one has ever done something like this for me.
While Dagon was processing the sheer insanity of Kasari's affection, Kasari stepped forward, drawing another card.
"The Moon." Kasari declared coldly. “I'll make you regret being born.”
He attacked first with the Knight's sword. With a forward dash, he unleashed a lethal left slash. The sword brushed Jogo's face, the volcano instinctively moving back just in time to avoid losing his head.
“Such speed!” Jogo exclaimed, genuinely amazed, before his expression hardened into pure, blazing fury. He charged a fireball the size of his hand to test the Kitsune's strength. Without a word, he threw it. Kasari parried the blast with his sword, cutting the flames in half with a second slash.
But during that very action, Jogo had already summoned ten more fire spheres, firing them in a rapid, devastating burst. Kasari dodged two, dashed left, and took cover behind a concrete pillar. He peeked out, watching Jogo float in the air using his fire like a jet thruster.
“Damn, clever use of the fire-bending,” Kasari commented casually.
“What are you talking about? You've seen too much Avatar!” Jogo retorted angrily. Using the massive rubble of the destroyed station, Jogo forged a colossal meteorite out of lava, ready to crush the fox into ash. The meteorite plummeted fast, leaving almost no time to react.
“Fine. I'll show you something,” Kasari said calmly. He unleashed a barrage of slashes that cut through the empty air. He looked almost like a lunatic trying to cut the intangible. Over and over, he split the air with his sword—and then, after a second, reality violently distorted.
Jogo blinked. He suddenly found himself standing exactly beneath his own falling meteor, while Kasari was hovering safely above it: their positions had been swapped!
Jogo looked around in total shock. “What happened…?” He looked up and saw his own meteorite crashing down on him. He immediately started to run. “Dammit!”
Kasari pushed himself down, literally kicking the colossal meteorite toward Jogo to accelerate its fall. “You're about to get flattened!” Kasari mocked him loudly in a foreign language Jogo couldn't even begin to understand.
Jogo turned one last time, seeing the molten rock just inches from his face. “Shit! N-not like this!”
It was over. Jogo was about to be crushed.
But suddenly, a violent, high-pressure jet of water struck the meteorite from the side, knocking it completely off course. It crashed harmlessly into the rubble right next to Jogo.
Dagon walked heavily toward the two of them. “That's enough. Jogo, he saved my life. And you, fox, stop hurting my brother.” With his arms crossed over his chest, it was a veiled command mixed with a desperate request.
Kasari glided down with celestial elegance, looking at Dagon. “Your brother? Are you sure? There’s absolutely no resemblance between you two!” He glanced at Jogo, who was furiously dusting off his lava mantle.
“Hmph. I don't care if you saved Dagon. The fact remains that you are human, and he is a curse. You will never be his partner,” Jogo spat, waving a dismissive hand at Kasari. “You'd better not interfere. You have no idea what we are trying to achieve here, white-fur.”
Kasari looked at Jogo, entirely unimpressed, and then turned to Dagon. “Bah. If it's a thousand-year plan by some delinquent who doesn't know what to do with his life, well, I'm not surprised.”
Kasari turned toward the exit, grabbing Dagon's enormous hand to pull him along. But Dagon immediately pulled his hand back.
“No. I'm not coming with you,” Dagon said firmly.
Kasari stopped. He looked at the Abyssal King with a serious, darkening gaze.
“I don't even know your name," Dagon continued, his voice trembling slightly. "And you learned my name from someone else. How can you call this love?”
Kasari turned fully around, staring at Dagon with the terrifying, irritated gaze of an entity as ancient as the universe itself. “Do you doubt me, Dagon? Do you think you can diminish my feelings?”
But beneath Kasari's angry words, a desperate, obsessive thought arose: No. You must be with me. No one has made me feel this way in billions of years. You are mine. It's a sign of fate, and fate never lies.
Kasari reached out and took Dagon's hand again. This time, his grip was forceful, laced with fierce, unyielding possession. He would not take no for an answer.
Dagon, feeling the overwhelming, intoxicating wave of the Kitsune's emotions pouring through the grip, finally surrendered. He let himself be pulled along. He turned his head back to look at Jogo one last time.
“J-Jogo... I'm sorry, but you'll have to continue the plan without me for a while.”
Jogo looked at him, enraged. Initially, he thought Dagon didn't want to go. But the more Jogo watched the scene, the more he noticed how tightly Dagon was squeezing Kasari's hand in return. The emotions radiating from the Sea Curse were far deeper than a simple "I don't want to go."
As an older brother, Jogo’s job was to understand his little brother. And if Dagon was bound to reach this point sooner or later... It wasn't normal for a curse. But Dagon was a curse born with pure emotions. He was the curse who openly wept for Hanami. Jogo knew it was destiny that Dagon would eventually fall in love with someone.
Jogo just never would have guessed that Dagon would fall in love with a half-human anomaly.
Chapter 2: The Man Who Destroyed Everything
Somewhere else in the burning station, Megumi was still hiding behind a cracked pillar. He had seen the entire horrific scene. He had watched Jogo casually burn Naobito, Nanami, and Maki alive. By pure, terrifying luck, Jogo had been too distracted by Kasari's intervention to target Megumi.
Moving silently toward Maki and Nanami, Megumi saw Naobito's charred ashes. “Dammit...”
Megumi knelt beside Maki, gently taking her hand. “Maki, are you okay?” he asked, his voice shaking. Maki was gravely injured, but thanks to her superhuman resilience and Heavenly Restriction, she had barely managed to survive the flames. She didn't answer; she had fainted from the agonizing pain.
Dagon and Kasari had left the station, and Jogo had continued with Geto's plan to awaken Sukuna. Megumi looked at Nanami, who was also in terrible shape, bleeding out on the floor. Megumi gritted his teeth, lifting Maki and Nanami over his shoulders to bring them to safety. They were incredibly heavy, and Megumi was already exhausted and wounded.
Shibuya Station was a complete disaster. Rubble and fire were everywhere.
That Dagon… Megumi thought, struggling under the weight. Calling him “the weakest” was an understatement. Dagon was anything but weak. Even if Jogo wiped us out instantly, it wouldn't have been so easy for him if Dagon hadn't worn us down first. What the hell is happening?
According to their calculations, Dagon was supposed to be the weakest of the Disasters. And yet, he had just found himself an ally who was far too powerful.
While Megumi was carrying his mentors to safety, he heard heavy, familiar footsteps echoing behind him.
Who could it be? Megumi asked himself, his blood running cold as the memory hit him: Toji Fushiguro was still in the area. And he had never been defeated.
Megumi turned slowly. Toji was standing there, gripping the sharpened remains of the Playful Cloud. Without a word, the Sorcerer Killer dashed forward to attack his own son.
Megumi instinctively dropped Nanami and Maki, his hands flying into a shadow sign to summon Nue. With his hands positioned like wings, the giant hawk appeared right behind him. With a screeching “Crooaawwkkk!”, Nue threw itself at Toji like a living projectile, striking him with a barrage of purple lightning. While Nue attacked from above, Megumi summoned his Divine Dog: Totality, the dark wolf appearing with the glowing red eyes of a predator.
Megumi knew he couldn't physically compete with Toji after what he had suffered against Dagon. But if he ran away immediately, Toji—or whatever demonic puppet this was—would kill Nanami and Maki.
“Come and get me, you bastard!” Megumi yelled, gesturing for Toji to follow, before throwing himself out of a shattered glass window. Toji, fueled by pure killing intent, followed him into the streets.
Meanwhile, Dagon and Kasari were finally outside the ruined station. Kasari was looking up at the Abyssal King with pure admiration and love.
“Dagon, I see you’re doing better…” Kasari purred softly, reaching up to caress the giant curse's wet cheek.
But Dagon gently caught Kasari's hand, pulling it away. “No, please... I… I don't… I can't love you," Dagon stammered. "I don't even know your name… and you were literally about to kill me a minute ago…”
Dagon's words fell like heavy weights on Kasari. The Kitsune's bright expression completely shattered, his ears drooping sadly.
I'm sorry… Dagon thought, his own heart clenching at the sight of Kasari's sadness. I'm just not ready yet… it was all too fast… b-but… I still want to try to be close to you.
Driven by an instinct he couldn't control, Dagon reached down, lifting Kasari slightly and pulling him into a kiss. It wasn't as desperate or feral as the first one in the domain; this one was intensely deep, slow, and passionate. When the kiss finally broke, Dagon's thick tentacles lingered softly against Kasari's face for a long second, as if physically detaching them would cause him pain.
Kasari immediately hugged Dagon’s imposing chest, wrapping his arms and twin tails tightly around his torso.
“T-then... it will just be an 'I care about you' for now…” Kasari whispered against Dagon's skin.
Dagon was stunned by Kasari's sudden, gentle compromise. But deep down, he knew the truth: beneath those soft words, Kasari would never give up on him. Never, ever.
A few blocks away, Megumi was fighting a losing battle against Toji. He had assaulted the assassin with an army of shadow rabbits, but Toji was simply too powerful. Megumi was running on fumes; he had to escape or he was going to die.
Hell… he looks exactly like me, Megumi thought frantically as he dodged a lethal strike. But… it can't be him… why now? Why right here? Why is he trying to kill me?!
Megumi didn't even have time to finish the thought before Toji was on top of him, ready to stab him through the heart with the sharpened Playful Cloud. Megumi threw himself to the side, dodging the blade by a hair. With a desperate hand gesture, he summoned Toad. He spawned the giant frog far away across the street. Just as Toji swung for Megumi's neck, Toad lashed out, catching Toji perfectly with its long, muscular tongue. It wrapped tightly around Toji's torso, pulling the assassin away before vanishing just before Toji could slice it in half.
It was the perfect distraction. Megumi had already taken a running start, sprinting desperately through the desolate, ruined streets of Shibuya—a city that had been full of life just hours before this ambush. Now, it was a graveyard where sorcerers had failed at everything.
Turning a corner, Megumi suddenly skidded to a halt. Standing right in the middle of the street were Dagon and Kasari, locked in their romantic embrace.
T-Them again! Megumi thought in horror. He glanced back over his shoulder. Toji was already closing the distance, his dead eyes locked onto the prey. Damn it! I just wanted to save Maki and Nanami!
Toji gained ground on Megumi in a fraction of a second. Megumi braced for the fatal impact... but Toji simply blurred right past him.
What? Megumi froze. Oh no. He… he attacks the strongest in the area… and the strongest here is…
Megumi's analytical thoughts shattered when he saw Toji's trajectory. Toji wasn't aiming for the Cosmic Kitsune. He was aiming directly for Dagon's back.
But why Dagon? Megumi thought wildly. Isn't Kasari stronger?!
While Kasari was having the best, most intimate moment of his 100,000-year life, the corner of his orange eye caught a metallic glint. The jagged tip of the Playful Cloud was approaching Dagon’s spine at supersonic speed.
“D-DAGON!!” Kasari screamed.
He didn't think. He shoved his towering husband out of the trajectory with all of his cosmic strength.
CRUNCH.
Kasari took the hit. The sharpened tip of the Playful Cloud impaled him, penetrating straight through his skull.
Blood—hot, wet, and undeniably red like a human's—poured out in horrific avalanches from the fatal wound. Kasari’s body slumped, but he managed to turn his head to look at Dagon one last time. Blood stained his white fur, but he offered his King a soft, devoted smile.
“...Kill him for me.”
It was the activation of a Binding Vow. The unbreakable contract of a Fate Weaver. Kasari fell to the asphalt, his physical body instantly dissolving into glittering stardust energy that scattered into the polluted night air. He was gone.
“Kasari… no…”
Dagon collapsed to his knees on the ruined street. A single, heavy tear fell down his crimson cheek, splashing into the blood Kasari had left behind. Dagon looked up and saw Toji standing there, a satisfied, dead smile on the assassin's face.
An emotion so strong it physically ripped at Dagon's chest exploded from his core. It was the most powerful feeling he had ever experienced in his existence. It was infinitely stronger than the destructive fury he felt for Hanami's death. This was something dark, ancient, and primitive. An emotion capable of destroying a person's very soul: limitless, unadulterated hatred for the monster standing in front of him.
“You… you cursed bastard.” Dagon’s voice wasn't a rumble anymore; it was a demonic, tectonic roar. “I’ll make you regret being born… for what you did to Kasari!”
Dagon stood up to his full, towering height.
And then… the concrete floor of Shibuya began to tremble.
“A-An earthquake!?” Megumi thought out loud, clutching a streetlamp for balance.
But Megumi was dead wrong. The terrifying scene he was about to witness was the true awakening of a Disaster Curse. Dagon, ranked by the sorcerers as the weakest of his family, was about to prove to the entire world that the Abyss bows to no one.
Water began to violently leak from the cracked asphalt. Small drops at first, seeping through the concrete, while Toji carelessly approached Dagon, aiming the bloody Playful Cloud right at the Abyssal King's forehead.
And then… the explosion.
From deep beneath the earth, an immense, immeasurable, apocalyptic mass of pressurized water erupted in roaring avalanches. Dagon's eyes were no longer yellow. They were a glowing, toxic green, overflowing with resentment, grief, and the most powerful catalyst of all: hatred.
More cracks spider-webbed across the city block. The streets shattered completely, geysers of ocean water flooding the entire district in seconds. Megumi watched in complete terror. He desperately summoned Nue, grabbing onto the hawk's legs to fly high into the night sky.
Looking down, Megumi witnessed the most destructive sight of his life. It wasn't just a single street. Twenty percent of Shibuya was completely submerged under Dagon's catastrophic inundation.
A giant hand made of crushing, high-pressure water grabbed Toji mid-sprint. The assassin was completely immobilized in the deep, raging current. Dagon didn't hesitate. He dashed forward, using his pelvic wings to propel himself through the water like a torpedo.
Before the impact, the space around Dagon's fist violently distorted.
The color red. The color black.
A perfect Black Flash ignited the dark waters, coloring the night sky of Shibuya with a violent, electric life. The colors spread out, arcing toward the full moon. Landing a Black Flash of that magnitude instantly pulled Dagon into "The Zone," elevating his combat performance to 120%. Dagon was becoming exponentially stronger by the second.
Dagon unleashed a merciless, relentless series of blows on the paralyzed assassin. Every punch painted the water with red and black distortions, like an artist violently slashing a canvas. But the artist here was the Sovereign of the Sea. Every single strike was gravely wounding Toji, crushing his ribs and internal organs.
Finally, using his sheer, superhuman strength, Toji broke free from the water construct's grip. Clinging desperately to Dagon, who was now fighting mid-air above the waves, Toji began to wildly stab at Dagon's face and chest with the broken Playful Cloud.
Splash.
A sound echoed. But it wasn't the sound of Dagon's blood, nor the sound of his skull breaking. It was the sound of highly pressurized water.
The harder Toji tried to smash Dagon's head, the more Dagon effortlessly created microscopic, high-pressure water shields that perfectly deflected Toji's blades. Even with Toji's immense, god-like speed, Dagon in "The Zone" wasn't just stronger; his reflexes had evolved. His technique showed a mastery never seen before. Creating tiny, perfect water shields consumed almost zero cursed energy compared to manifesting a full barrier, allowing him to fight endlessly.
Fed up with Toji's pathetic struggle, Dagon moved. With blinding speed, he grabbed the Playful Cloud right out of Toji's hands. He snapped the sharpened tip off the weapon and, with a brutal thrust, shoved the jagged metal straight into Toji's eye.
A violent spray of blood erupted, covering Dagon's enraged, unblinking face. Toji, completely destabilized and screaming, fell backward into the flooded, sunken city below.
The water was suffocating. The pressure was crushing, so heavy that Toji felt like he was moving in slow motion, far worse than when he had been inside the Skandha.
Dagon hovered menacingly in front of him. But the true horror was forming behind the Abyssal King. From the pitch-black darkness of the deep water... a shadow appeared. A shark.
No... not an ordinary shark.
A Megalodon. Gigantic, towering as high as a skyscraper. In fact... it was taller. This wasn't a simple prehistoric beast. It was the ultimate apex predator, forged from the deepest hatred and grief fueling Dagon's Disaster Tides.
Chapter 3: The True Power of the Abyss
Megumi watched from the sky, utterly horrified.
Hell… is this guy… stronger than Jogo?! Megumi thought, his mind racing. No… Jogo’s raw output is stronger… but Dagon… he is special. His emotions make him infinitely more terrifying than the other three curses!
Megumi's analysis was cut brutally short. A stray Shikigami—a violent byproduct of Dagon's untamed fury—leaped from the water and bit deeply into Megumi's arm. Megumi cried out, bleeding heavily, and fell from Nue's grasp. He crashed down hard, rolling onto the solid roof of a skyscraper that was barely tall enough to survive Dagon's high tide.
That guy Toji… is he dead? Megumi thought, clutching his bleeding arm. I… I have to talk to him... if he really is the person I think he is…
Megumi dragged himself to the edge of the roof, looking down at the flooded warzone.
Dagon was standing tall and victorious on top of his giant Megalodon, riding the colossal beast like a true Sovereign of the Sea. The Megalodon's gigantic, jagged jaws opened wide as Toji fell helplessly through the air. The jaws snapped shut with a sickening crunch, swallowing the Sorcerer Killer whole, exactly as he fell right between its teeth.
It was over.
A few minutes later, the chaotic fury of Dagon's Disaster Tides finally calmed. Shibuya was still a flooded ruin, but the currents and the water had returned to a deep, eerie calm. Dagon's surviving Shikigami swam peacefully around him while the King stood silently atop his giant Megalodon, staring at the water where Kasari had vanished.
Suddenly, a faint light caught Megumi's eye. Behind Dagon, a shimmering trail of cosmic stardust slowly began to materialize from thin air.
That is… the fox spirit's cursed energy… Megumi realized, his eyes widening.
In a matter of seconds, the stardust trail expanded, swirling around Dagon. It didn't carry an ounce of malicious intent; it wrapped around the giant red curse like a warm, desperate embrace.
The stardust slowly solidified, dissolving the light to reveal Kasari. The Kitsune's arms and twin tails were already wrapped tightly around Dagon's broad, trembling shoulders and chest.
Kasari looked deep into Dagon's vibrant green eyes, and Dagon stared back, his breath hitching in his throat.
“I... I thought you were dead…” Dagon whispered, his broad, trembling hand reaching up to gently touch and caress Kasari's soft, white cheek.
Kasari leaned into the touch, a smug, endlessly loving smile spreading across his muzzle.
“You cannot kill the universe, my King,” Kasari replied softly. “Or at least... not permanently.” He lied... but it was for a greater good, he just couldn't let Dagon know he would've died permanently if it wasn't for the binding vow.
The End.
(It is a WIP, what did you expect?)
Hope you guys liked it!
I really put alot of effort in this, like SO MUCH.
fun fact:
"Jogo looked around in pure shock. “What happened…?” He looked up and saw his own meteorite crashing down on him. He immediately started to run. “Dammit!”
Kasari pushed himself down, literally kicking the massive meteorite toward Jogo to accelerate its fall. “You’re about to get flattened!” Kasari mocked him loudly."
in my italian version this was an italian joke, in Italian "what happened" (cosa è successo) and Kasari would've replied with "the toilet pipe is broken!" (si è rotta la canna del cesso!) because "successo" and "cesso" make a rhyme!
before you go:
I'd really like if u guys told me which parts you liked the most, and also tell me if u saw some grammar mistakes (those translators are kinda shit when trying to translate literal italian into english), that would make me genuinely happy and help me alot with making better stories!
Thank you for reading!
