1) Shoutout to the MILGRAM team for not taking the easy route of “Mikoto being better off/happier as a singlet anyhow.” The emphasis on him feeling alone, and not being able to cope with his memories by himself… Based off these voice lines, it seems like they’re leaning hard into the idea that Mikoto had DID because it was necessary.

A/N: I added a BONUS next day AFTERMATH! Where Mikoto comes back and doesn’t remember anything his other personality did!
Amongst the prisoners in Milgram, you were different. You were the first to notice Haruka. First to talk to him. Asked him simple things—Did you eat today? Do you need help with that?—things no one else bothered to ask.
The attention was addicting.
The way your voice softened when you spoke to him. The way you didn’t laugh when he fumbled with tying his shoes or struggled with writing his name. The way you always waited for him. The way you forgave his crimes, seeing his regret…
You weren’t just nice.
You were perfect.
Soon, Haruka found himself watching you more than he should. Memorizing your schedule around the prison. Finding excuses to be near you. Walking the same prison hallways you did, sitting at tables where he knew you’d pass by. Even when you weren’t looking, he was always there—lurking in the background, watching from the corner of his eye, his heart skipping a beat whenever you smiled.
You were perfect for him. Even if you thought your we’re doing nothing more than showing simple kindness due to the scary circumstances in Milgram, he saw it as way more.
He needed to make you his but he had no idea how to confess. He never saw his parents get along well in a loving relationship so he had no example of how it worked. So he went to one of the adults in Milgram he thought might know how to help.
“Just t-tell her…?” Haruka’s face burned as he fidgeted with the hem of his oversized prison uniform sleeves, avoiding Mikoto’s amused gaze.
The older guy leaned against the wall of the prison common area, arms crossed, watching Haruka with a smile. “Yeah, Haru-kun. You like her, don’t you? Then tell her.”
Haruka squirmed. “B-But what if she s-says no?”
Mikoto chuckled. “Then you have to accept that. I’m sure you two can still be friends!”
Haruka paled like the idea was unthinkable. “B-But I—”
Mikoto sighed, ruffling Haruka’s hair like an older brother. “Listen, Haru-kun. Confessing isn’t about making her say yes. It’s about being honest. If she doesn’t feel the same, then that’s how it is.”
Haruka bit his lip, eyes darting away. That’s NOT an option. You had to feel the same. You had to.
Still, he nodded, pretending to take Mikoto’s advice to heart. “O-Okay… I’ll try it.”
Mikoto grinned. “Atta boy.”
It was supposed to be romantic…
Haruka had practiced in front of his rabbit plush a hundred times in his cell—how he’d stand tall, how he’d look you in the eyes, how he’d say your name in a deep, confident voice.
None of that happened.
Instead, he was a stuttering, shaky mess.
“I-I—I w-wanted to s-say—”
You blinked at him, tilting your head in confusion. “Haruka? Are you okay?”
Oh god. You looked worried. Not flustered. Not excited. Worried.
Haruka’s breath hitched. This wasn’t going right. This wasn’t going right at all.
From around the corner, Mikoto crouched and watched, his expression twitching with secondhand embarrassment. “Oh, my—!” His fingers scratching through his scalp in stress. “Haru-kun, you’re killing me here…”
Suddenly a flicker of something dark passed over Mikoto’s face.
Then he stilled and closed his eyes.
When his eyes opened again, they weren’t the same, the previous gleam lower in his pupil.
A smirk curled at his lips, his posture shifting into something far more domineering. “Tch. You really can’t do anything right, huh, Haru-kun? That’s ok, I’ll help you out.”
This wasn’t going to be just Mikoto helping anymore.
Before you could process what was happening, a strong arm wrapped around your shoulder, pulling you flush against a broad chest. The scent of Mikoto’s usual cologne was still there—but something in his demeanor was off.
It was oddly aggressive compared to the Mikoto you’d known. And it was terrifyingly forceful.
Your breath hitched. “Mikoto—?”
“Tch-” Orekoto mouthed in annoyance. His arm around you tightened, his smirk widening as he turned to Haruka, who was staring in shock and embarrassment. “You were taking too long, so I decided to help out Haru-kun.”
Haruka’s lips trembled. “B-But—”
Orekoto rolled his eyes. “What? You wanted her, didn’t you?” His fingers trailed along your shoulder, making you shiver. “Then take her.”
You tensed, trying to figure out if this was some prank the two men were playing on you. “W-Wait—”
Orekoto ignored you, his grip on your wrist tightening as he started walking. “Come on. We need somewhere private for you two, come one Haru-kun.”
Haruka hesitated for half a second before following, his heart hammering in his chest. His confession hadn’t gone the way he planned.
But maybe… maybe this was better. He couldn’t help the shy grin he had as he followed behind Orekoto and your smaller body being pulled along.
❤︎❤︎❤︎❤︎❤︎❤︎❤︎❤︎❤︎❤︎❤︎❤︎
With a sudden, forceful motion, Orekoto grabbed your wrist and dragged you towards Haruka’s prison cell. He threw open the door and shoved you inside, causing you to stumble and fall backwards onto the narrow prison mattress.
"Mikoto, what are you- ah!" Your protest turned into a gasp as he crawled over you, pinning your wrists above your head. His eyes, dark and intense, bore into yours with a hunger that made your heart race.
"Be quiet!" he said, his voice a low, dominant growl. One of his hands released your wrist to grip your chin, forcing you to meet his gaze. "Right now, I'm going to help Haruka claim what's his. I'm going to teach that fucking virgin exactly how to make a girl feel good."
Haruka stood nervously at the foot of the mattress, his cheeks flushed a deep, mortified red as he watched Orekoto manhandle you. His hands fidgeted and twisted on hem of his uniform, unsure of what to do with himself.
"M-Mikoto, is this okay?" Haruka asked, his voice small and hesitant. "Aren't you being a little too rough with Y/N?"
Orekoto shot Haruka an exasperated glare over his shoulder. "Rough?! Haruka! Do you want her or not?!?! Earlier you were a blabbering mess and she couldn’t take you seriously. You need to assert yourself, show her that she belongs to you."
Turning his attention back to you, Orekoto gripped the bottom of your top and yanked it up and off in one swift motion, exposing your bare skin to the cool air of the Milgram prison cell. His calloused hands skimmed over your flesh, leaving tingles in their wake.
"First things first," he purred, his thumbs brushing over your hardened nipples. "Get her worked up. Touch her like she's the only thing that matters. Like she's your whole world."
Haruka took a small step closer to the mattress, his eyes wide and uncertain as he reached out a shaking hand to cup your breast. He squeezed softly, marveling at the supple weight of it in his palm.
"L-Like this? Mikoto? Is this right?" Haruka asked, his voice pitching higher with nervousness. His thumb brushed over your nipple, sending sparks of pleasure shooting through you.
Orekoto smirked as he watched Haruka's hand explore you. "Not bad Haruka. Now, don't be shy. Really touch her," he growled, his voice a low, dominant rumble. "I want to see you slide your fingers inside her tight little cunt. Get her dripping wet and desperate for your cock."
Haruka's breath hitched at the crude words, his face flushing an even deeper shade of red. With a shakey nod, he trailed his hand down your stomach, his fingertips dipping teasingly beneath the waistband of your panties. He could feel the heat from your core showing how ready you were.
"I-I'm going to put my fingers inside now, Y/N... Okay?" Haruka said, his voice barely audible. He hooked his fingers into the side of your panties and tugged them down your legs, baring your glistening sex to his hungry gaze.
Orekoto grunted in annoyance. "Stop asking for permission, Haruka. Take what you want. Claim her."
With a deep breath, Haruka pressed a finger against your slick folds, feeling your wetness coat his digit. He slowly pushed forward, watching in awe as your tight walls stretched to accommodate him. He couldn't help but let out a soft moan at the incredible feeling of your silky heat enveloping his finger.
"Y-Y/N... you're so tight," Haruka gasped, slowly pumping his finger in and out of your clenching sex. He added a second finger, then a third, stretching you open as he curled them inside you, stroking along your inner walls.
Your back arched off the mattress, a loud moan escaping your lips as Haruka's fingers hit a particularly sensitive spot inside you. Your hips bucked against his hand, seeking more of that delicious friction.
"That's it, Y/N. Take his fingers like the needy little slut you are," Orekoto taunted, his voice a dark, dominant growl. He could see how close you were to the edge, could tell your body was tensing and quivering with impending release. "But don't you dare come. Not yet."
Haruka looked at you with wide, worried eyes, his fingers stilling inside you.
Orekoto's eyes flashed with dark intent as he watched you teetering on the brink of climax, your velvety walls clenching desperately around Haruka's buried fingers. He could see the needy, almost painful desire etched into every line of your body, and it only fueled his own growing arousal.
“Stop," he commanded, his voice a low, authoritative bark. Haruka froze, his fingers still knuckle-deep inside your fluttering sex. "Don't let her come, Haruka. Not yet. You need to mark her first, claim her as yours properly."
Haruka whimpered, he felt his dick twitching in his pants, holding back his own desperate need. With shaking hands, he withdrew his fingers from your dripping core, ignoring your whines. He fumbled with the fastenings of his pants, his cock already straining against the confines, eager for freedom.
"I-I need to...I need to put it in, Y/N?" Haruka asked, his voice high with nerves and anticipation. His cock sprang free as soon as he tugged down his pants and underwear, slapping against his stomach. It was flushed a deep, angry red, the tip super leaky with need.
Orekoto smirked at the virgin Haruka struggling to hold back his desperation. "Yes, Haruka. Claim her cunt. Bury yourself inside her and don't stop until she's overflowing with your seed. Until everyone knows she belongs to you."
Haruka nodded, positioning himself between your spread thighs. The head of his cock nudged against your entrance, slipping through your slick folds to catch on your opening. He looked down at you, his eyes wide and pleading. Though he kept hesitating… afraid to hurt you…
"I-I'm going to...AH!" Haruka gasped.
Growing impatient with Haruka's hesitant pace, Orekoto had moved over to behind Haruka and placed his hands on the small of Haruka's back, pushing the nervous boy forward so he smashed into you. The force of Orekoto's actions drove Haruka's cock deep into your tight channel, forcing you to stretch to take in his girth.
"A-Aah! W-Wait..." Haruka gasped, his eyes widening at the sudden tightness of your walls.
“Shut up and fuck her already," Orekoto growled, his hands gripping Haruka's hips tightly as he helped to drive the boy's movements.
Once he started to get a pace going for himself and Orekoto slowly backed away. Haruka could feel the way your velvety walls gripped and fluttered while his cock split you open.
"Don't hold back. Ravage her cunt until she can't walk straight. Until she's dripping with your cum and everyone knows she belongs to you." Orekoto instructed.
Orekoto's dominant words spurred Haruka on, and he began to move with more urgency, his hips slapping against yours as he drove his cock in and out of your dripping sex. The lewd sound of skin slapping against skin filled the small Milgram prison cell, mingling with your needy moans and Haruka's increasingly desperate panting. Thankfully everyone else was enjoying their food in the dining area and had no idea what was happening in prisoner 001’s cell.
To keep you from trying to get away, Orekoto reached out and grabbed your wrists, pinning them above your head with a grip that was just shy of painful. He leaned down, his lips curling into a smirk, his breath hot against your skin. "That's it, take Haruka’s cock like a good little slut. Don't you dare try to run away from Haruka's dick."
Haruka moved his hips slamming against yours with increasing force. The head of his cock kissing your cervix with every powerful thrust.
Watching the erotic scene unfold before him, Orekoto couldn't help but grow harder by the second. The sight of your restrained form writhing on the prison mattress, impaled on Haruka's desperate cock, was almost too much to bear. He could see the tears of pleasure streaking down your face, hear your needy moans and cries as Haruka pistoned in and out of your soaked cunt.
With a low, almost feral growl, Orekoto reached down and freed his own aching erection from the confines of his pants. It sprang out, long, hard, and already leaking with need. He grasped your chin with his free hand, turning your head to face him as he tapped the leaking crown of his cock against your tear-stained cheek.
"Open your mouth, slut," he commanded, his voice rough with desire. "Put that pretty little mouth to work."
As if in a trance from the undeniable pleasure, you parted your lips, allowing Orekoto to slip his thick length into the warm, wet cavern of your mouth. Your tongue swirled around the head, lapping up the salty essence leaking from the tip. Orekoto groaned at the sensation, his fingers tightening in your hair as he began to slowly thrust his hips, fucking your face with shallow pumps of his cock.
The lewd slurping sounds of the blowjob seemed to drive Haruka wild, spurring him to pick up the pace of his own thrusts. He pounded into you with renewed vigor, the force of his movements causing your body to slide up the mattress with every snap of his hips. The new angle allowed him to drive his cock even deeper, the thick length kissing your womb with every pass.
Haruka's breathing grew ragged and shallow, his rhythm faltering as he rapidly approached his peak. With a strangled cry, he slammed his hips forward one last time, burying himself to the hilt inside your spasming cunt as he found his release. Thick, hot ropes of his seed painted your insides, filling you with his essence as he shook and shuddered above you.
“Y/N! I love you so much! You always gave me attention and I haven’t been able to get out you out of my mind. I won’t let you leave me or deny me ever. I only need you and you only need me!” Haruka whined as he came.
The feeling of Haruka's cock pulsing and throbbing inside you, pumping you full of his cum, was enough to push you over the edge as well. Your inner muscles clamped down around him like a vice, milking every last drop of his release as your own intense orgasm crashed upon you and you passed out.
Orekoto groaned low in his throat, the erotic sight of you and Haruka lost in passion pushing him over the edge of his own release. He yanked his throbbing cock from your slack mouth, aiming it at your face as thick, hot ropes of his seed erupted from the tip. Pearly strands of cum painted your unconscious cheek, marking you as a possession, a toy of their shared use.
With a satisfied grunt, Orekoto wiped the last drops of his essence from his softening cock, smearing the excess over the swell of your breast. He tucked himself back into his pants with a smirk, the evidence of his debauchery written all over your peaceful, sleeping face.
Turning to Haruka, who was still buried to the hilt inside your limp form, Orekoto patted his shoulder. "You did well, Haru-kun. I'm happy you were able to confess your feelings to Y/N. If you ever need any more…’help’…with your relationship in the future, don't hesitate to come to me. I’m sure I will gladly be able to help you again."
Haruka looked up at Orekoto, his face flushed and glowing with happiness. He couldn't stop smiling, reveling in the knowledge that you were finally, truly his. "Thank you Mikoto" he said softly, gently brushing a strand of hair from your face.
With a satisfied nod, Orekoto turned and walked out of Haruka’s cell, leaving you and Haruka alone together in the aftermath of your shared arousal. As the door swung shut behind him, Haruka curled his body around yours protectively, holding you close as you both drifted off into a peaceful sleep.
BONUS Next Day!:
The next day, Mikoto woke up in his own cell as he blinked awake with a soft yawn, his mind foggy and confused like he had forgotten something... He could feel a strange, unfamiliar dampness in his pants, and he wiggled uncomfortably on the mattress in his cell.
Rising from his mattress, Mikoto stretched and got himself out of bed. He went to brush his teeth and got on a fresh pair of pants and underwear deciding to discard the previous wet ones embarrassed that Es or Jackolope might comment if they saw the obvious wet patch during an interrogation.
Mikoto decided to head to the cafeteria to grab a bite to eat. He made his way out of his cell and towards the communal dining area.
As Mikoto entered the dining area, he spotted Haruka sitting alone at a table, snacking on a fluffy mound of cotton candy.
"Hey there, Haru-kun! Mind if I join you?" Mikoto asked in his usual cheerful tone as he approached the table where Haruka sat, completely oblivious to what his other personality had done the previous night. He pulled out a chair setting down his tray and sat down across from Haruka.
Haruka's head shot up at the sound of Mikoto's voice, his eyes wide and anxious. He seemed to tremble slightly, a flicker of uncertainty and guilt in his expression. It was clear that he was wondering whether Mikoto remembered the details of their shared encounter with you the previous night.
"U-Um, h-hello Mikoto..." Haruka stammered nervously. "You... you want to sit with me?"
Mikoto tilted his head in confusion at his nervous voice. "Huh? Of course, Haruka. Why wouldn't I want to sit with you?" he asked with a soft chuckle. "We're friends, aren't we? By the way how did your confession with Y/N go yesterday?"
Haruka told him it went fine and you accepted thanks to his… advice. And Mikoto hummed satisfied with himself, having no clue of what Orekoto had forced upon you, or the role he had played in your defilement…
Now your sleeping body is hidden, tucked under the blankets of the mattress in Haruka’s cell hugging his rabbit plush, for him to now be able to enjoy all of your attention.
