꒰ᐢ. .ᐢ꒱ . Imagine being in the Death Note universe and you can’t die.
Notes: I’ve written stuff about death note, I might just post it—I got really bored and started writing about it, I’m also glad people were interested in this idea! Thank you !
Someone knocked on the Yagami residence. Sayu opened the front door. "Big brother! Someone's here for you!"
Light walked downstairs and opened the door and froze.
You stood on the front step, exactly the same as the last time he saw you. Same face & same clothes.
Holding a convenience-store bag while smiling politely, you said, "I think you dropped this yesterday." Inside the bag… was a magazine he had fake-bought as a decoy and accidentally left on the park bench while watching you. "I figured it belonged to the guy following me."
Light didn't move and just stayed silent. Beside him, Ryuk slowly leaned over his shoulder. "Light—I don't like this—they creep me out." Light didn't answer and Ryuk's grin had disappeared.
His Shinigami Eyes could see your name. They could see everyone else's lifespan. But where your remaining lifespan should have been… there was nothing.
Ryuk laughed once at it, but now it surely confused him. it was still funny, but thats because he didn't know what you were.
Light looked into your eyes, for the first time since finding the Death Note… this had never happened, it was impossible. his expression was composed perfectly calm—he nodded, but he couldn't hide the fact that this was unbearable to him.
"Impossible." He had written your name. He had also heard you collapse. Yet, why were you standing on his doorstep as though yesterday had never happened.
"Hi, are you okay? I said you forgot this," you repeated, holding out the notebook.
Light accepted it carefully. "Thank you."
"You should probably be more careful," you said with a small shrug. "Someone else might've taken it."
"I'll keep that in mind."
You smiled politely. "Well, see you around." and left his residence.
"Light." Ryuk's voice broke the silence.
Ryuk scratched the back of his neck. "I've watched humans for a long time and I've never seen… whatever that is."
Light didn't answer. Instead, he walked straight upstairs, shut his bedroom door, and locked it. The Death Note landed heavily on his desk. He opened it immediately. Your name was still there. Exactly as he'd written it. "…Why?"
He tried again, different cause of death, different time. and different place.
The following afternoon, he found you sitting alone outside a convenience store, eating cheap bread while absentmindedly watching people cross the street.
You looked up. "It's you again."
Light forced a pleasant smile. "Well, Tokyo isn't exactly a small city, and I live nearby."
"That is true." You took another bite. "I know what you're thinking.” Your smile dropped while you looked at him in the eye. “Even if you wanted to, I won't die at all."
"That's a very strange thing to say," Light said, his voice smooth, with a tone that was both confusion and mild amusement. "You won't die at all? Why would you say something to someone you just met?"
He was testing you. He needed to know exactly how much you understood, and if you could or had bypassed the absolute law of the Death Note, and—most importantly—if you were an enemy who planned to expose him to L and the task force.
You simply looked up at him, dusting a few crumbs of the cheap bread off your clothes, with your expression entirely unbothered by the so called “god of the new world”standing right in front of you.
I know exactly what you did in that alleyway yesterday. And I know what you did to try and fix it when you got back to your bedroom."
Beside Light, Ryuk let out a low, wheeze of a laugh, his massive yellow eyes darting between the two of you. "Oh man, Light... they're completely calling you out. They know, they complete know !"
Light didn't blink. His mind was racing at a million miles per hour, analyzing every answer and detail . If you knew about the Death Note, if you knew he was Kira, why hadn't you gone to the police?
Then, the answer clicked in his head. In the police database. When he had hacked his father's computer, and saw your file. To the entire world , you were officially deceased.
Your legal existence had been wiped out years ago. If you walked into a police station to report Kira, they would treat you as a fraud, just like they did when you first crawled out of that forest. You had no leverage to expose him to L because you literally did not exist to the system.
“I don't know what you're talking about," Light replied, keeping his voice low so the passing pedestrians wouldn't overhear. Its best not to out himself, he leaned slightly closer, his tone dropping into something far colder, the mask slipping. "But you're making a lot of bold assumptions for someone sitting alone outside a convenience store."
"They aren't assumptions," you said, standing up and brushing the remaining crumbs off your clothes . Your unchanging, sixteen-year-old face looked entirely serene, "what your using has a lot of rules. But whoever—or whatever—wrote those rules didn't account for what happened to me"
Ryuk then tensed, the Shinigami king, missed something? Then , you took a step toward him, "You can write my name again. You can try a car accident, a disease, or another heart attack. My body will just melt away, the police will find an unidentifiable corpse, and I'll wake up a few hours later in a different alleyway, looking exactly like this," you whispered, gesturing to your face. "Does that make you annoyed, Kira?”
Light stood entirely frozen, his fists clenching inside his jacket pockets. and then you left.
Light did try it again. He could not stop himself, he wrote your name, specifying a fatal car crash at a precise intersection.
And he watched from a distance as a speeding delivery truck jumped the curb and crushed your physical shell into the concrete.
Yet, less than four hours later, you walked right up to him on his way home from cram school, entirely uninjured, holding a plastic bag filled with bright red apples.
Ryuk had nearly choked on his own spit, seeing the bag and cackling wildly at Light’s pale, sweating face. Light’s absolute power was a total joke to you.
But the real problem started when L found out about you.
L had been reviewing the bizarre deaths of the teenagers who murdered your family. He noted that their sudden heart attacks and suicide matched Kira’s pattern, they would’ve assumed it was normal but due to their conviction it tied them to Kira.
However, their pre-death panic about a "sixteen-year-old ghost" caught his attention.
L used the Task Force database to cross-reference recent security footage around those men, your face popped up. A kid who had officially been declared dead years ago, completely unchanged, caught on camera right before each man died. That connected you to Kira, maybe.
Within forty-eight hours, L had his covert operatives track you down and bring you into the Task Force headquarters.
Now, you sit in a spinning chair inside the brightly lit, monitored room. L is crouched on his own chair, with a lollipop resting between his lips, staring at you through his dark, sleep-deprived eyes.
Light stood just a few feet away next to his father, Soichiro Yagami, while matsuda, mogi, and watari were on the opposite side. keeping his face perfectly stoic, though he was anxious, terrified of what you might say.
"It is highly unusual," L says, his voice flat, tapping a spoon against a teacup. "According to forensic record, you died years ago. Yet here you are. light, what do you think of this?"
Light desperate to steer L away from the truth. "It’s bizarre, Ryuzaki. But it's likely a case of plastic surgery and identity fraud. They are a victim’s tragic past to torment those criminals, and Kira just simply executed them separately."
You spin slowly in your chair, looking back and forth between the brilliant detective and the secret mass murderer. You look at Light, giving him a small, knowing smile that says “I could ruin your entire life right now.”
“But it does not explain why her fingerprints match the missing victim's childhood medical records exactly. DNA is unchangeable …Furthermore..."
L leaned forward, restacking his feet onto the cushion of his chair so he was practically balled up into a tight knot. He stared right into your eyes.
"Those teenagers died of sudden, unexplained heart attacks and suicide, That is Kira's exact moves. Yet, the police reports state they were screaming about a ghost before Kira supposedly judged them. So tell me..." L paused, biting down on his lower lip. "Are you an accomplice of Kira?“
The room went entirely silent. Everyone was looking at you.
Light didn't move a single muscle, but his eyes were burning into the side of your face. Underneath his, calm expression, his mind was screaming. If you told L about the Death Note, or if you even hinted that Light was the one who tried to kill you in that alleyway and killed you again and an incident with that delivery truck, Light’s plan for a new world would shatter instantly.
Beside Light, the invisible form of Ryuk was floating upside down, his massive grin stretching across his terrifying face. He was practically vibrating with excitement. "Oh man, Light! Look at your dad's face, look at L! They're putting them on the spot!"
You calmly spun an inch to the left in your chair, totally unfazed.
"I am neither," you said smoothly, crossing your legs. "I want to make it clear that Kira killed those teenagers but it wasn’t executed properly” yeah shift the blame to Kira, Light thought, “and as for me...as you suspect, I can’t die..Kira tried it three times, I just simply exist.”
The entire room froze at your response. L tilted his head, his thumb resting against his bottom lip. "What do you mean?”
Light quickly cut in, "Perhaps they mean that Kira wanted the credit for punishing those murderers, Ryuzaki. Kira hates when other people take the law into their own hands. And if this person was stalking them and driving them to insanity, Kira might have stepped in to end the entire thing and claim the judgment for himself."
L didn't look away from you. "Is that true? Did Kira kill them to steal your revenge?"
You let out a soft, mocking laugh, looking directly at Light. "Kira doesn't care about revenge. He cares about his own ego. Isn't that right, Light?"
"If what you are implying is true... that Kira tried to eliminate you and failed... then your survival defies every known law of biology, medicine, and human nature. You claim you cannot die. And that claim can be easily tested."
L reached into his pocket and pulled out a small, sterile, stainless pocket knife. He slid it across the smooth surface of the desk toward you. "If you are truly outside the system of life and death, prove it. A simple cut across the palm will suffice."
Light’s chest tightened. No. Not here. Not in front of the cameras. If you cut yourself and healed instantly, L would completely abandon all other leads and focus entirely on the supernatural element.
L would realize that Kira’s power was different , bringing him dangerously close to figuring out the mechanics of the Death Note.
"Ryuzaki, wait," Light interrupted, stepping forward with a perfectly crafted look of moral outrage. "This is crossing a line. We are investigators, not torturers. We cannot force a teenager—regardless of their legal status—to harm herself in the middle of an investigation—It's unethical."
The task force all nodded alongside Lights statement except watari.
L didn't look at Light. He kept his eyes on you. "I am not forcing them, Light. I am inviting them to validate their own statement. If they are human with a lifespan, they will refuse because of pain. If what they claim to be... pain is irrelevant."
You looked down at the gleaming silver knife, then up at Light's pale, rigid face. You smiled, with a mocking expression. "I don't mind proving it. But I'm not doing it right here like a lab rat in front of an audience— Excuse me. I need to use the restroom."
You picked up the knife, stood up from the spinning chair, and walked out of the bath room before anyone could stop you.
"Light, Soichiro-san, Mogi-san watari come here and Matsuda keep watch on the door," L commanded immediately, spinning his chair around to face the massive wall of security monitors while biting his lollipop.
"Ryuzaki!" Soichiro barked, his face red with anger. "The bathrooms are private! We cannot spy on a people in the restroom!"
"Ordinarily, yes," L said, his fingers flying across a keyboard. "But The executive bathroom contains a thermal and standard camera override for high-risk suspects. If they are a fraud, we will see them fake the injury. If they’re is telling the truth..."
Light didn't say another word. He practically pushed past his father to get a clear view of the monitors. He hated that he was forced to watch, but he was also curious
He needed to see it. He needed to know if his Death Note was truly powerless against you. Behind him, Ryuk hovered, his massive eyes practically glued to the screen.
On the main monitor, the feed flickered to life. The bathroom was large, featuring a deep, tiled bathtub alongside the standard fixtures.
You walked in, entirely uncaring—that they were watching. You didn't hesitate to look up and smile, while you walked straight over to the bathtub, stepped inside, and sat down against the porcelain wall.
With a completely blank, serene expression, you raised the knife. You didn't just nick your finger.
To put an absolute end to Light’s denial and L’s skepticism, you drew the blade sharply across your own throat.
On the monitor, Light’s breath caught in his throat. Soichiro gasped, and mogi was just staring still covering his mouth in pure horror.
Dark, heavy blood immediately began to spill out, splashing against the white porcelain of the tub. Matsuda immediately opened the door seeing your body slumped sideways, and your eyes going completely glassy and vacant.
But a second later, just as you had warned Light in that alleyway, the rules of your curse took over to protect your identity.
The moment your heart stopped beating, your physical shell began to rapidly, violently change.
The skin on your face bubbled and withered, your features melting away into an unrecognizable, decayed state within a matter of seconds.
You had vanished, leaving behind a horrific, unidentifiable corpse in a pool of blood.
The monitor room went dead silent, save for the hum of the computers. Everyone looked like they were about to vomit. And matsuda in the camera was frantic not knowing what to do.
L froze, his hand stopping halfway to his mouth, his mind completely short-circuiting at the sight of absolute biological impossibility.
And Light? Light’s hands began to shake inside his pockets. Because he knew, with absolute certainty, that somewhere out there in Tokyo... you were already opening your eyes, completely unharmed, and the same.
The monitor room remained entirely frozen. The heavy silence was broken only by the low, steady hum of the computers.
Soichiro Yagami stumbled backward, his face completely pale as he gripped the edge of a desk to steady himself. "What... what did we just watch? That's impossible... human flesh doesn't disintegrate like that! Ryuzaki, what is this?!"
L didn't answer right away. He sat hunched in his chair, his thumb pressed so hard against his bottom lip that it turned white.
His dark eyes were wide, staring at the screen where the unidentifiable, melted mass lay in the bathtub.
For the first time since the Kira no in any case even the BB murder case couldn’t compete to what he had seen, L was visibly shaken.
Light stood perfectly rigid next to him. To his father and L, Light looked like a horrified student processing a traumatic event
Light was also in absolute agony. His teeth grinding together so hard his jaw ached. “It’s real.”
Beside him, Ryuk let out a low, breathless screech of a laugh, his long fingers scratching his bald head. "Hehehe... This is the best thing I've seen in a thousand years!"
The next morning, the task force was still in shock with what had happened yesterday while they were thinking, L was silent patiently waiting. Then the heavy electronic lock on the monitor room door clicked.
The heavy metal door slowly swung open.
Every man in the room spun around, their bodies tense, hands instinctively flying to their holstered firearms.
You stood in the doorway and just smiled and waved.
You were wearing the exact same clothes, completely unsoiled. Your sixteen-year-old face was entirely flawless, without a single scratch, speck of blood, or scar on your neck.
You held a plastic bag carrying cake, and made your way to a table and placed it down while everyone was keeping a distance and some had their fire arms out.
You gave them an incredibly serene smile. "Did I over did it ? What do you think?"
Aizawa screamed, drawing his pistol and pointing it at you with shaking hands. "Stay back! Don't move! What are you?!"
“Put it down Mr. Aizawa,” L slowly stood up from his chair, his posture still slouched, but his gaze locked eyes with you "A gun will clearly do nothing but waste our ammunition and ruin the carpets."
L walked forward, stopping just three feet away from you. He leaned in close, inspecting your neck, your face, and your clothes without actually touching you.
"Incredible," L whispered, his dark eyes gleaming. "You died. And your body underwent rapid, deterioration to protect your identity, and yet you walk through our front door completely fine.“ L continued muttering to himself checking the neck, “say do you like being thsi way unable to die?”
You didn’t respond, then L turned his head slightly, looking back at Light, then back to you.
"You said earlier that Kira killed those teenagers to clean up a mess," L said, his voice dropping into a desperate, intense pitch. "You have survived him Kira as you said and If you cannot die, then you are the ultimate weapon against Kira."he then looked at your wrist “Kira knows about your existence since you claimed that he killed you three times.”
L bowed slightly, his eyes never leaving yours. "I am officially requesting your assistance in the Task Force. Help me catch Kira. With your absolute immunity, we can force him into a corner he can never escape."
Light’s heart stopped. His vision went completely black for a fraction of a second. If you joined L, if you stayed by L's side, it was only a matter of time before you casually dropped his identity just to watch him squirm.
Light looked at you, his eyes wide with a silent, desperate, unspoken plea—Don't do it.
You looked past L, locking eyes and your smile grew just a little bit wider.
Light felt a cold sweat break out across the back of his neck. His mind scrambled, his pristine composure threatening to crack right in front of L. “Dammit L”
He had to stop this. He had to get you out of this room before you completely dismantled his life.
"Ryuzaki, wait," Light said, stepping forward, forcing his voice to sound reasonably concerned rather than completely panicked. "Think about this logically. We don't know what they are, after a gruesome suicide on our screens. Even if they are immune to Kira, how do we know they aren’t a threat to us?“
L slowly straightened his posture, his thumb returning to his lip as he looked at Light. "Light makes a fair point. However, i believe that they won’t do anything to harm, I supposed…. And their immunity to death makes them the perfect shield and…Kira’s absolute power relies on the fear of mortality... while they have none." L turned back to you. "Where would you like to start?"
“Anything is fine, Ryuzaki, I don’t think I’m much help but I’ll gladly be here, after all…I don’t really have much to do since I don’t really exist.” You walked right past L, your shoulder brushing his as you stepped directly into Light’s personal space.
"Hehehehe!" Ryuk howled from the ceiling, flipping upside down to stare directly into Light's wide, trembling pupils. "They got you, Light.”
Light’s jaw tightened so hard a muscle twitched in his cheek. He forced his lips into a stiff smile, though his eyes were opposite to that polite smile he wore. "I'd be happy to help you get acclimated to our investigation," he said, his voice dripping with forced warmth.
L had made you stay next to Light’s side
For the rest of the afternoon, you didn't look at the computer screens. You didn't read the files on the victims. You didn’t help at all.
Instead, you spent hours casually playing with a shiny silver pen, clicking it rhythmically. Click. Click. Click.
Every single click happened every forty-second. When Light took a notice you just grinned at him making another clicking sound.
Whenever Light tried to focus on his laptop, typing up notes to appear busy, you would lean over, your shoulder touching his, looking at his screen.
"That's a very detailed analysis of Kira's timeline, Light”you whispered, your breath warm against his ear. "You seem to know exactly how he thinks.“ then you made a clicking sound with your tongue.
Light’s fingers froze on the keyboard. He didn't look at you, keeping his eyes glued to the monitor,"I'm just trying to be thorough…If we want to catch a monster, we have to understand how he operates."
"A monster?" you murmured back, letting out a tiny, amused chuckle. "Is that what he is? I thought he was the god of the new world, what do you think about that Light?"
Out of the corner of his eye, Light saw L watching the two of you from his crouched position, his dark eyes observing the intense, quiet murmuring between the two teenagers. L couldn't hear what you were saying, but he could see the rigid, unnatural posture of Light’s spine.
Light couldn't tell L the truth without exposing himself. He couldn't kill you because you were entirely immortal. And now, he was forced to sit next to you, completely aware that at any given second, you could leaned over to L and end the game forever.
L didn't miss a single thing. He sat in his chair, eating the cake you had brought and his dark eyes shifting between you and Light.
L already knew that you knew Light was Kira. He could see it in the way you deliberately talked to Light, and he could see it in the way Light’s perfect composure was completely rotting from the inside out.
But L also knew that your word alone wasn't enough to convict the son of the Chief of Police. Even if he had you as proof, it was hard to prove it.
He needed hard, undeniable proof—kira already made a in a fatal mistake with killing you thrice.
When the rest of the Task Force left for a dinner break, leaving only you, L, and Light in the main room, L casually threw his trap onto the table.
"Light," L said, his voice completely flat as he stacked four sugar cubes on top of each other. "I have been thinking”.
“Our new friend claims that Kira tried to eliminate her three times. Once in an alleyway, and one with self inflicted and the last one was with a delivery truck. If Kira is truly as meticulous as we believe, he must be completely losing his mind over her continued existence."
"Yes," L murmured, looking up playing with his messy hair. "In fact, I believe Kira is so desperate to fix this situation that he would do anything to get them alone.
“Therefore, I am assigning you to be their personal escort outside the headquarters. Wherever they go, you will accompany her. Alone. Without wiretaps or surveillance."
Light’s fingers stopped completely. He slowly turned his head to look at L, his face a perfect mask of bewildered frustration. "Ryuzaki, that's incredibly reckless. If Kira attacks us—"
"Kira cannot kill them," L interrupted smoothly, a tiny, chilling smile touching his lips. "And if Kira attacks you, Light, then we will finally have our proof of your innocence plus you too act incredibly close, so It is simply a perfect arrangement."
You let out a soft giggle, leaning back in your chair and kicking your legs back and forth. "I think it's a wonderful idea. Light can be like a friend for me. Isint that right, Light?"
Light looked from L’s deadpan stare to your wide, mocking smile. He knew exactly what L was doing. L was using you as live bait to trigger him.
And Light hated your guts he wanted to rip you apart, to erase your unchanging sixteen-year-old face from the earth, to scream at the top of his lungs—but he couldn't do a single thing.
If he refused, he looked guilty. If he agreed, he’ll have to deal with it.
"Fine," Light said, his voice dropping into a dangerously calm, low tone. "If you think it's best for the investigation, Ryuzaki. I'll be with them."
Ten minutes later, the two of you were standing alone in the concrete parking garage beneath the headquarters, waiting for the elevator, you wanted to buy bread so Light had to tag alongside with you.
The silence between you was suffocating, light finally snapped.
He slammed his hand against the wall right next to your head, leaning down until his eyes were inches from yours.
"What do you want?" Light hissed, “You don't care about justice. You don't care about L. You don’t care about Kira.”
“You're just a parasite clinging to my world because you have nothing else to do. Tell me what it takes to make you disappear, or I swear to God, I will find a way to make you suffer for eternity, even if you can't die."
You didn't even blink. You just tilted your head,“your squishing the bread light.” With your smile perfectly intact.
Yeah Ryuk is having a field day with this one, he is seeing a-lot
