A/N: Why did this get so long? So much dialogue =.=

Again, these scenes are NOT IN ORDER.

Your name is Hiroshi Takeyama, 36-year-old talk-show host and occasional children's author, remarkably fit and with absurdly bright blue hair. The person you live as now is also a wonderfully flamboyant one; when you break into your brother's newest lair, you do so wailing.

"You killed Nana-chan!" You cry dramatically, finger extended right at Aniki's metal mask. Shimura Nana has been dead for almost a full year. Aniki is unamused.

"You were the one who set her on me. I do hope you weren't expecting me to spare her?" His voice is very, very soft. Oh dear. You drop your hand and use it to scratch the back of your head sheepishly.

"That... wasn't really my intention, Aniki. Sorry for the trouble?" You laugh awkwardly.

"Then what was your intention, exactly? Surely there were less troublesome candidates to entrust One for All to." His fingers start up a slow drum on the armrest of his frankly impressive chair. He's probably not actually as angry as he presents himself, but his temper has been getting nastier over the years. Best you not push him. You wipe the trappings of Hiroshi Takeyama off your demeanor, and meet his eyes when you answer him.

"My intention was to put nii-san's legacy in the hands of someone he would've approved of. The sixth holder was pathetic, but didn't Shimura Nana seem like someone nii-san would've wanted to wield One for All? A hero?" When he stays silent, your voice turns a little plaintive. "She was such a sweet girl. I'm sorry she went and interfered with your business, but did you have to kill her in such a pitiful way?"

Aniki gets up abruptly and walks off, waving at you to follow. It's not an apology, but it's pretty close to forgiveness.

You let Takeyama settle back over you, and trail after him into an ominously dark hallway. This would be a pretty good setting for a story, actually—buzzing lights, exposed piping, following a super-villain into the depths of his evil lair-

"Brother. Have you been involved with the eighth wielder?" Aniki interrupts. You blink out of your fantasizing and sheepishly tuck away your notepad.

"Nana's successor? Nah. Shimura Takeshi died before his daughter ever met young Toshinori, remember? And Hiroshi Takeyama was just an occasional babysitter for her son."

"Hmph. I can't be bothered to remember all the lives you've taken." Ignoring your mutters of how mean, Aniki, he demands, "You'll keep your distance from this one."

That pulls you up short. "Whaa? Why?"

"Consider it a concession. I won't kill this wielder until One for All has been passed on, but you've been getting too involved with the succession lately. Live your life, brother, and stay on the sidelines." At the slightly mulish expression that crosses your face, he adds, "I won't tell you twice."

You throw your hands up. "Alright, alright! I won't interfere except to make sure the kid passes One for All on. He's already got himself a decent mentor, anyways, so there's no need for me in his life."

"Good. We're here."

Here is a heavy metal door, one that locks from the outside. So Aniki didn't send you his base's coordinates just to scold you. Well, it makes sense. Aniki's current body is probably getting on in its' years.

Sure enough, there's a lab behind the door, with two operating tables left out. One has a trembling body strapped to it, face already bandaged in preparation. The other, meant for you, is strapless and even has a pillow ready; how thoughtful.

You leave Hiroshi Takeyama at the threshold—that man would be horrified at the situation, and you have no use for him here. Instead, you are entirely All for One's youngest sibling when you step forward to examine the body. A teenager, you think, though it's a little hard to tell under the thick black clothes. Definitely male, because Aniki gets strange about being a woman. "Isn't he a little younger than you usually go for, Aniki?"

You give Aniki a teasingly suggestive smirk. The body flinches, fingers fisting in fear. Huh, awake and lucid. Aniki must not want to wait for any drugs to flush out.

"That doesn't concern you," Aniki sighs, and motions for you to get on with it. You hop onto the table meant for you, but don't lie down just yet.

"Is that one," you jerk your chin at the other table, "going to have an actual name?"

You've asked this every time, and just like always Aniki replies, "All for One," and gives you that particular bemused look of his. You frown as you swing yourself fully onto the table and lie flat.

"'All for One' again. Do you even remember your name?" You've asked Aniki this before too.

"Do you, Eye for an Eye?" He retorts, and doesn't wait for a response before settling his hand on your face. "I'm taking your Quirk now."

You close your eyes, and don't double-check with him to make sure he'll put your Quirk back. There's no need. After so long, you trust him.

(When you wake up, 'All for One' is puttering about the lab, face newly melted into that odd featurelessness that comes from holding so many Quirks. The straps on the neighboring table have been neatly unbuckled, and when you swing your legs onto the floor you almost put your foot into the cooling puddle of blood. Aniki makes an amused noise at your mou of disgust, and passes over some cleaning supplies. Together, the two of you efficiently mop up the evidence, and you get a good look at Aniki's old body before he uses one of his many Quirks to burn it into nothingness.

Its throat was slashed, possibly with a scalpel. The teenager inhabiting the corpse would've bled out quickly.

You wonder what the boy's name was, and you don't ask.)

You're supposed to be Nanatsuki Reiko, 68 year old retiree and grandmother of seven. You're not. Reiko would never be able to stomach coming here, with the intentions you have.

"Hello, All for One," you greet sedately. Aniki glances up from his busywork, and absently waves off the grunts pointing guns at your face.

"Leave us," he dismisses. His men disperse obediently. You give them an unimpressed look as they haphazardly shuffle away, and sit opposite Aniki without waiting for an invitation. Your joints creak in protest.

"Youth these days are so undisciplined," you sigh. "Your men need some shaping up; they're unsightly."

Aniki finally deigns put down his pen and look at you. "You usually time your visits better so you don't have to see them to begin with," He drolls. "It's been a while, sister. You're looking old."

You know how he means that comment, but you feign offense anyways. "Nonsense. I don't look a day over forty, brat. Show some respect for your elders." You grin wickedly at him.

"Not old age? Then what brings you here?"

"Ahh, well. Yes old age, as a matter of fact. I need a little favor, Aniki."

"More than usual, I take it? You haven't brought anyone with you this time."

"Yes. I spent too long living this life, and perhaps enjoyed it a little too much. Nanatsuki Reiko doesn't have a believable reason to die, so I need to arrange her untimely murder. Your help would be appreciated."

"That should be simple enough. Who will you be next, then?"

"My youngest grandson. Daichi Takashi, four years old. His Quirk lets him animate drawings."

"So young? Won't you be put into the foster care system?"

"He's still got his parents, but my Kyoko's been mostly leaving his care to me, and that fool she married won't pay any mind to a little change in their son's behavior."

"Alright then. I expect you'll be leaving your current body here?"

"Yes. I intend for Reiko to go missing today and her body to turn up a while later. You'll be gentle with Takashi-kun, won't you?"

"Of course. I'll see you in a few years, sister."

(The next day, you wake up as Daichi Takashi, four years old, to the news that your beloved grandmother has gone missing. Two days later, your father tells you that Reiko-obaasan was found in the river, her neck broken. You cry at the news, and over the following weeks your mother quietly frets over your drastic personality change.

Five years later, you are Daichi Takashi, nine years old, and you are finally old enough to spend your Saturdays unaccompanied. Your mother's friends coo over how mature you are for your age. Your father's proud of you.

You break into Aniki's latest lair to reclaim your Quirk, and greet him with a beaming smile and a, "Hi, All for One!"

Aniki glances up from his paperwork, sighs, and waves off the grunts pointing guns at your face. This time, when they leave you two alone, they march in orderly lines. Your smile is probably uncharacteristically smug for a 9-year-old.)

Your name is Taneka Toshiro. You are 52, a highly successful businessman, and under investigation for being an accomplice in a human trafficking ring for children with powerful Quirks.

You are absolutely guilty of what the police suspect you of, though not nearly as much as they like to imply you are. Your business was just a front for a while, and though you were fully aware of what some of your recent hired hands were up to, you never touched those kids.

Your lawyers deny all accusations, of course. Your business partners kick up a fuss. The media goes wild with speculation. Everything's going according to plan.

…Except the part where you've been imprisoned. You were meant to incriminatingly escape from your house arrest in the middle of the night, lead the heroes and cops on a merry goose chase, and choose to die rather than be brought to trial where your heinous crimes would undoubtedly be brought to light. Unfortunately, one of the officers assigned to your case has some manner of foresight Quirk, and knew that if you were allowed to return home you'd run. How annoying.

There's only one person you can trade with who won't kick up a fuss over being in jail. Well, two, technically, but you're not sure if Aniki's right hand is still the same man as from last time; it's been a while. So you wait until nighttime, when you're left alone to sleep, and hope Aniki's not doing anything important when you trade with him.

You blink into awareness in the body of All for One, and fortunately it seems like you are alone. Not so fortunate is the fact that you are standing in a lab, pouring a mysterious substance from a canister into another mysterious substance in a beaker. You carefully cap both and put them down. Hopefully you didn't just ruin whatever this is.

You blink back into the body of Taneka Toshiro. Aniki has arranged your body so that you're lying face down on the cell bench, face pressed onto your folded arms-a position of utmost exasperation. How dramatic.

Still, cavalry's on the way. The situation's still salvageable.

(The next day, the police investigation turns up documents suggesting that Taneka was the mastermind of the ring. Taneka himself isn't available for questioning, seeing as the man killed himself in his cell. Some of the children are returned to their families. Others are found dead and -though the official reports don't show this- Quirkless. The men involved with the ring are summarily arrested or simply disappear; the case is closed, and the police move on to other matters.

In a different prefecture, you read about the mess on the newspaper, and tell Aniki that next time he should probably arrange his own scapegoats. Aniki agrees with you, and quietly lets 16-year-old Umukuri Shinsui live his life.)

"Sister," All for One starts, before you can even greet him. "I have a favor to ask of you."

Your name is Shiragaki Kagome, 19 and newly orphaned as of last week, and you take no shit from anybody.

"Hi Aniki. I'm doing well, thank you for asking. Not sure I can say the same about you, though," You fire off, closing the lid of your laptop and swiveling around on your computer chair. "You know, I was beginning to think All Might actually killed you, you didn't get in touch for so long."

You stand, hand on your hip, and waggle a finger at him disapprovingly. You're in your humble abode, a little apartment above the pet store your mother ran. Tomorrow, you're going to have to go down there and familiarize yourself with all the animals and goodies before you can confidently open up the shop again.

Aniki looks almost hilariously out of place in your cozy bedroom, but then Aniki has an aesthetic that isn't really suitable for anything but torture chambers, shady business meetings, and unethical labs. "You were hanging around heroes again. I wasn't sure it was wise."

Excuses, excuses. "You've been getting paranoid in your old age, Aniki. Old Chuuzei-sensei was merely checking up on nii-san's legacy before her health nosedived. You did quite a number on the man, you know."

"Yes. It was...a favor he repaid in kind." Aniki touches a hand to his side, where one of a number of worrying tubes is inserted. You hadn't realized that they were anything more than some oddity of a new Quirk.

Kagome is discarded like so much chaff. "Aniki? Are you alright?"

"I'm fine," he says, and doesn't elaborate. This fails to reassure you at all.

"You know, I'm pretty sure I can trade with All Might. Find someone to pass One for All to, train them up a little, and then succumb to a fatal relapse of old injuries..." Your voice is uncharacteristically cold, but someone has hurt Aniki. Aniki has actually sought you out instead of sending you his location and letting you come in your own time. "Shiragaki Kagome's mother died just last week, too. It's not inconceivable that she would commit suicide."

You don't target One for All wielders, but you're willing to make an exception for Aniki.

Aniki, who is a stubborn ass, tuts at you like you're being ridiculous. "That would be far too seemly a death for him. No, you don't need to concern yourself. Just mind your own business," he refuses, brusquely but not unkindly meant. You sigh.

"Fine then. Are you here to borrow Eye for an Eye?" You flop down onto your bed. Kagome is coming back to you, in spurts and trickles, and she prompts you to fold your arms behind your head cross your legs casually. "You're probably hurting, right? Did you hide a body in my closet or something?"

Aniki shakes his head at you, and solemnly sits in your desk chair. You squint an eye at him—uneasy, but not quite willing to show it. "What are you here for, then? You haven't paid me a social call in... god, at least a century."

Aniki—fidgets. There's no other way to describe it. You haul yourself upright, slowly, incredulously; you're pretty sure you're staring. "Sister. I have a favor to ask of you," Aniki repeats, and it suddenly hits you that he's reciting something, like—like some green teacher reading a speech off of prepared notecards. "Will you hear me out?"

"...What is it?" You prod, when he seems unwilling to continue. "You know I don't mind you asking."

"I'm... You know the work that I do. The empire that I've built up, over the ages." Aniki seems inexplicably uncomfortable. You haven't the faintest idea why—he knows you don't have a problem with how he chooses to live his life. You nod encouragingly anyways. "I'm getting tired of it, sister. I want to stop. And the best way to do that would be to refrain from using your Quirk for a while."

"What?" Your voice is a weak, paltry little thing. "You... want to die?"

That's a stupid question. You're bizarrely ashamed it even came from your mouth. You can feel Aniki shooting you a judgmental Look through his mask. "No. I want to retire peacefully. I want the whole world to remember the name All for One, and feel sure that he is dead. I want to leave my empire in the hands of a trusted successor."

"Okay. That seems reasonable. What is it you want from me, though?"

Ah. The uncomfortable countenance is back. You still have no idea what it means. "You watch over One for All's successors, and guide them when they need it. Can you do that for mine, too?"

"I can try my best, Aniki, though I've gotten more into the habit of training heroes. But I'm only going to do it if you're too dead to do it yourself."

"I'm quite likely not going to be available."

"Right then." You sit up and plant your feet on the ground. "Explain that to me. What's your big plan, Aniki? What going on, and what do you need from me?"

Aniki steeples his fingers, like the stereotypical super-villain he is. "I'm going to pass All for One on, and I'm not sure I'll be able to guide my successor properly. You remember Tomura, don't you?"

Hmm. You nod. "Yeah. Smart kid, bit of a brat. You're sure he's ready to fill your shoes, though? If you give up All for One, we won't both be able to use Eye for an Eye anymore."

"No, Tomura isn't ready. And I'm not sure he will be by the time things come to a head either. I don't want him to fill my shoes, sister, I want him to step into his own." Aniki folds his hands in his lap, and turns his head towards the window. You're pretty sure he can't actually see anything through that mask, but maybe he's picked up an appropriate Quirk somewhere.

"I'm not too worried about after. I won't be able to retire peacefully knowing that there's still more I could've done for Tomura, anyways. But I've got a good handle on how All Might is. We were fighting to death that day, sister, and he didn't want to kill me. He stood over where he thought I'd died, and said it was an accident."

There's a certain kind of disgust in Aniki's voice that you've never really understood, though you recognize it. He used to speak similarly of when nii-san would meddle in his business, or of particularly troublesome heroes. It would make you nostalgic if it weren't for the bitter undertones of genuine hatred.

"I'm going to fight him again, after both of us have lit the torches of our successors. And I'm probably going to lose. But he won't kill me, just arrest me. If I'm executed, that'll be fine—the whole world will believe I'm dead. But if the courts sentence high-security incarceration instead of execution, I'm going to have to be there to convincingly die of either neglect or old age, and no one will be there to guide Tomura and help him grow while I'm in prison. So I'd like you to do it."

That's... fairly comprehensive. You wonder how long Aniki has been cooking up this scheme for. "I don't think that'll work. Tomura-kun has never really listened to me, and you want him to be independent and headstrong. Maybe... no, there's no point in trying to break you out or do anything suspicious on your end, is there? That would just be counterproductive."

Aniki sits patiently as you mull the situation over. He seems a little expectant. He probably already knows the conclusion you're going to come to and is waiting for you to reach it, the manipulative jerkwad. "So. Can't do your job for you, can't break you out openly. Then what you're actually asking is if I'll live as 'All for One' in prison for a few years, right?"

"Maybe." He's smiling behind his mask, you can just hear it. "Can you play me convincingly enough?"

You draw yourself up, and Kagome tightens around you ready to huff and puff and blow his challenge right down. "Of course I can, Aniki. Do you doubt my abilities?"

"No. Of course you can," he echoes softly. "Would you really be willing, then?"

"I suppose I would. A few decades in prison aren't much in the long run, and what's a little favor between siblings?" You smile at him companionably. "I'd like to know why you suddenly feel the need to have everything settled this generation, though."

Aniki gets distinctly more awkward. It's kind of fascinating to watch. "I... lost that battle. Utterly," he finally admits, and suddenly things make way more sense. Aniki and his ego. "All Might destroyed more of my work in one fight than anyone's managed in a lifetime, and the next One for All wielder is only going to be stronger. I can grow with All for One to keep up, but I don't want to be locked in that kind of endless cycle of fighting."

"Does it...bother you? That nii-san's legacy is always fighting you? I could try to change that," you offer, but even to yourself your words sound dubious. It wouldn't be right for One for All to be in the hands of anyone but a hero, and Aniki is far too set in his ways to flourish as anything but a villain.

"No. It's... fitting, that this is way things are." Aniki sounds like the admission pains him a little. You get that. "But I've been doing this for a long time, and Tomura is the most promising successor I've ever found. I want to see what he can become, with this power, in this fight. I'm sure he'll grow into something devastating."

Wow. Aniki sounds nearly smitten. It's sweet of him. And here you'd thought he only liked little Tenko-kun because of old Nana-chan.

"Alright." You cough, a little awkwardly. "Well, it's better if you're the one with Eye for an Eye when that final battle goes down, right? So you can use it trade with me, and I can use it trade out at the end. Do you want to take it now?"

"Not yet. Closer to the time when I'll fight that despicable All Might. I just came to check if you'd be willing to take my place in death."

"Always, Aniki. I'll cheat death for you as many times as you need me to."

"Are you who I'm supposed to meet?"

Your name is Shiragaki Ayame, the sole 37-year-old owner of a small line of chain stores. Your recently departed husband left them to you in his will, so you are currently well-off (if somber at his passing).

Today, however, is not a day dedicated to the upkeep of Shiragaki Ayame. Today is the first of November, and you are having a picnic among the cherry trees. Like every year, you spread a perfectly white cloth over the dry leaves; like every year, you watch as the bare branches rattle in the wind and spend the day as Eye for an Eye, just reminiscing.

There are very few people who know of this little tradition of yours; fewer still who would have cause to seek you out here, on this day, instead of through more convenient means. So you're not polite, slightly-distant Ayame when you answer the subdued-looking boy, but relaxed, sprawled-out Eye for an Eye.

"I just might be. What brings you here, kid?"

"...Sensei sent me." The kid steps forward to loom over you, and sneers ever so slightly. "Said I'd find you here, and that he has a favor to ask of you."

A favor? That...really only sounds like it might come from one person. Though that doesn't explain why Aniki's sent a kid to you, today of all days. He usually avoids contact with you on the anniversary of your middle-sibling's death.

You're careful to keep any confusion out of your manner when you ask, "Well then. What's he want?"

The kid shuffles his feet a little, but steadfastly holds your gaze. "He said I need a safer place to stay full-time than the base, until I'm high-enough level that the mobs and underlings won't give me trouble."

...What the hell? You're not going to say no, of course, because Aniki's asking this as a favor, but really now. What's he thinking, slapping you with a kid out of the blue? Aniki's head's only getting to be a more and more complicated place as time goes on, and you can't keep up so easily anymore. "Sensei, huh? Do you know his name? Or mine?"

The kid gives you a look that sizes you up, considers you suspicious, and conveys just how unimpressed he is with you all at once. Maybe it's the implied association with Aniki, or maybe it's just because of the day you've spent thinking about the past, but for some reason your brain jumps right to how much this kid acts like a tiny, brattier Aniki. It's almost cute.

"Yes, and no."

"Well, if you don't know already, then my name is Shiragaki Ayame. What's yours, kid?"

"...Shimura Tenko."

You freeze. "Would your father be Shimura Tomura, by any chance?"

Tenko-kun goes tellingly stiff. Aniki you asshole, you think, as you lever yourself into an upright position. "Right, never mind that. Have a seat, Tenko-kun, and tell me a bit about yourself." You pat the cloth invitingly.

The grandson of Nana-chan gives you a dirty look for being so familiar with him, but carefully sits down anyways. "I'm ten. Father is dead. I like video games, and I hate heroes and NPCs, and I'm gonna kill All Might." He crosses his arms and gives you a belligerent, challenging look, clearly expecting you to return the introduction.

Mini-Aniki. Definitely a mini-Aniki. You take a moment to fight off a mocking coo, and then blatantly ignore the brat's attempts to socially pressure you into reciprocating. "Nice to meet you. Am I supposed to train you in anything, or are you just with me for a civilian cover?"

"Sensei's going to be teaching me everything I need to know. He says I'll go see him when the other kids have school. I'm just staying with you for sleeping and eating, because Sensei has better things to do with his time."

"Hmm." Sounds like most of Tenko-kun's time for the next few years will be spent living in your house. "We'll need to change your name, then. Did Aniki provide you with any papers?"

Tenko-kun blinks very slowly at you, apparently trying to decide what to address first. Finally, he asks, very cautiously, "...'Aniki'?"

"Ahhh. That ass you call Sensei. Who sent you to live with his darling little sister, apparently without giving you a cover story or me a proper heads-up."

Tenko-kun's reaction is hilarious. Horror hits him one way, mortification another, and fury runs them both over until his poor face doesn't know what do with itself. You can see exactly how upside-down his whole view of the situation has just turned; he probably thought you were some kind of semi-civilian lackey. He pulls himself together admirably quickly, though.

"...Don't call Sensei an ass," he grumbles. He can't seem to decide between being respectful or being annoyed. You very manfully bite back laughter.

"We're family, I'll call him whatever I want to."

Mini-Aniki gives you a calculating brand of stink-eye. "You don't look old enough to be Sensei's sister," he suggests, all sly-like. You huff.

"So you know how old Aniki actually is, do you? I'll take that as a compliment. Now, a name. Shiragaki Ayame's got two brothers and a sister somewhere. We'll tell anyone who asks that you're my nephew, since you'll be staying at my house, so 'Shiragaki something'. You pick."

Tenko-kun thinks about it for a long moment. "...Tomura. Shiragaki Tomura," he offers.

"That's a good name," you tell him, and your smile is a tinge bittersweet. Tomura-kun eyes you curiously.

You lay back down. The sun's starting to set, but you're not quite ready to go back to being Ayame yet. With Tomura shifting impatiently next to you, it feels a little less lonely here, this day, watching these same old trees grow. Aniki probably sent this kid to interrupt you purposely, right?

"Hey, Tomura-kun," you tell the sky. The boy twitches a little, unused to the name—you'll have to train him out of that. "You wanted to know why I look so much younger than my brother, right? Tell me honestly: do you know what Aniki's Quirk is?"

"Yeah. He...said it's called All for One." He watches you out of the corner of his eye, still so cautious. It's not a bad trait to have, if he's really running after Aniki. You hum encouragingly. "It lets him take other people's Quirks."

"Mmm, that's right. We had a brother, too. Everyone thought nii-san was Quirkless, which wasn't such a terrible thing when we were young. He was the one who mostly raised me. But nii-san wanted to be hero; it was hard for him, to be weak while Aniki was so powerful and doing so many things nii-san didn't agree with.

Aniki knew this, of course. He could tell; he was our brother. So even though he knew nii-san would probably cause him some trouble, Aniki gave nii-san a simple Quirk to fight with when I asked him to, as long as I agreed to let Aniki use my Quirk to live as long as he wished and to let nii-san die in his own time. So nii-san became a hero, and him and Aniki fought for half a lifetime, and when nii-san died Aniki thought that'd be the end of it. Only- well. Did Aniki tell you about One for All?"

Tomura-kun wipes the hungry look off his face, and shakes his head. You briefly wonder if you should really be telling this to the kid, but shake the doubts away. If Aniki didn't want you talking, he shouldn't have sent someone to interrupt your day so unexpectedly.

"Alright then. Nii-san did have a Quirk, and that Quirk was to give other people his Quirk. The two Quirks mixed into one, leading to a strengthening Quirk that could be passed on to others. So at some point before he died, nii-san passed on his Aniki-given Quirk to someone else, who passed it on again to someone else, and so forth. That leads us to today, and to the current wielder of the One for All Quirk. Who is All Might."

Tomura-kun jerks. You roll over onto your stomach and prop your chin up on your hands, staring silently. He fidgets under your heavy-lidded gaze. Ill at ease, he demands, "Why are you telling me this?"

You smile. Tomura-kun's a smart kid; it's probably what Aniki sees in him. "I'm telling you this because Aniki has sent you to me today, specifically, on the very anniversary of the day he killed nii-san. I'm telling you this because I have spent a good part of the last two hundred years making sure that One for All -that my nii-san's legacy- is carried on by someone he'd approve of. Aniki has agreed to hold off killing its' wielders until they've had a chance to pass it on... but you're not Aniki." You lower your voice, and Tomura-kun leans in ever so slightly. Your words are incredibly gentle when you say, "I'm telling you this because you said you want to kill All Might, and if Aniki's taken you on then he believes you can do it. So consider this a warning, Shimura Tenko: if you destroy the only thing I have left of my beloved nii-san, I will erase you."

Oddly, the threat to his life appears to put Tomura-kun more at ease. It's honestly a little sad to see. He sneers at you, scoffing, and challenges, "Oh yeah? And how is a side character like you going to do anything?"

You shake your head. "Ah, I haven't told you about my Quirk yet, have I?" Of course not; you'd been hoping you wouldn't have to. Ah, well. "You see, my Quirk isn't a flashy one like my brothers'. It's called Eye for an Eye. It lets me switch bodies."

Tomura-kun harrumphs. "So what," he mutters, though his gaze takes a turn for the wary. "That's how you and Sensei have lived so long, right? You just switch to a younger body when your current one gets too old."

"Correct. Well done. However, that's simplifying things a bit. Quirks are a part of the body too; so if I were to switch with, say, you, I'd end up in your body with your Quirk, and you'd end up in my body with Eye for an Eye."

"So it only works if Sensei's there to take it from the old body and put it back in you." Tomura-kun sounds torn between fascination and disgust. You beam; he really is a bright boy. "What good is it in a fight, then? I'd just use it to switch back."

"I suppose you could; there's no cooldown time for Eye for an Eye, after all. But you're still missing two very important pieces of information, Tomura-kun." Your voice has taken on a slightly lecturing tone. Hoshitake Yuuto, the person you lived as before Ayame, had a fairly enjoyable career as a teacher—you hadn't realized you missed it. "First: I don't need to be near you to use Eye for an Eye. I don't have to touch you, or see you, or know where you're hiding—I just need to know who you are." Tomura-kun makes a face. You smile at him softly.

"The second is that Eye for an Eye is a Quirk that doesn't die. Maybe it didn't used to be this way, but it's a Quirk designed to enable body-jumping and it's been shuffled from person to person for centuries. So if its host were to meet an untimely end, it would come to the last person to use it—namely, me. Or sometimes Aniki, when he borrows it." You roll over onto your back, to give Tomura-kun a moment to compose himself. "Obviously we didn't know that at first, so yes, I used to take people to Aniki when I wanted to become someone else, and Aniki would put Eye for an Eye back in me and help me clean up the old body. But even back then, our Quirks made it so that there'd be no point to us fighting—he can't stop me from using my Quirk on him from a distance, I wouldn't be able to stop him from using it back, and we'd both just end up playing a game of hot potato with my body as the thing you don't want to be left holding when the game ends and the one in Aniki's body kills the one in mine. And even then, whoever it is could just switch with someone else at the last moment -say, you, or All Might- and then that unrelated person would die in my body, and the one in Aniki's would know that the other wasn't dead since Eye for an Eye would go to the person in yours or All Might's body. It'd be stupid. So we just don't cross each other."

You glance up, and hold Tomura-kun's gaze. "That's why you shouldn't do something that I'd have to kill you for, Tomura-kun. If you snuff out nii-san's Quirk, I am going to, oh, jump off a building and trade places with you before I hit the ground. Then I'll be Shiragaki Tomura, and I am going to dedicate that life to destroying everything the Tomura of before built. There's going to be nothing of you left. And then I'll be someone else after that, someone who'll probably have to do Aniki a huge favor. But Aniki won't try to kill me for it, because neither of us wants to fight and there's too much of a chance he won't win."

Again, Tomura-kun looks strangely comfortable with his life being threatened. If anything, you doubting Aniki's ability to kill you seems to be what has him the most riled up. "But why doesn't Sensei just take your Quirk and keep it? It doesn't sound like he needs you at all," Tomura-kun complains. He sounds horribly put out.

The Shiragaki Ayame in you wants to scold her nephew for being rude. The real you just chuckles at him. "What's the point of him holding a Quirk that he can't use? He lets me keep Eye for an Eye because he can't use it without preparing a body first, or else he'll lose All for One. As for why he leaves it to me, specifically... Well, I told you, brat: we're family. It's been almost two hundred years—we're all we've got left."

You reach out and steal a quick hair-ruffle. Tomura-kun flinches away from your touch—something else you'll have to train him out of, if he's going to be posing as your nephew.

"Plus, it doesn't hurt that I'm willing to do favors for him from time to time, like look after his rude little children."

Your name is Shiragaki Kagome, 23 year old owner of a gardening shop. It used to be a pet store, but you decided a few years ago that gardening was the thing for you.

There's a man who you keep an eye on. Toshinori Yagi-san is cheerful, charming, and occasionally coughs up blood. He's been visiting your shop semi-frequently, ever since you accosted him on the road while handing out flyers for your remodeled shop's grand opening. Sometimes you seek him out to check up on him, because you are a concerned friend.

Today, you find him at Dagobah Beach, which. Well. Your aunt Ayame remembers it as being rather pretty, when she was young and still alive. He's there with a boy, and you are surprised to recognize Midoriya Izuku—fourteen, single mother, decently fit and with no social life to speak of. You keep track of a list of such concerning children in the back of your head, though Midoriya has always been pretty low thanks to his bullied and Quirkless status.

Yagi-san is undoubtedly training the boy, though. You don't get too close -wouldn't want to intrude, after all- but it warms your heart to see your self-appointed charge taking an interest in the next generation.

That night, you are Eye for an Eye, and you send your Aniki a message. "It's almost time. Is my dearest nephew ready?"

A/N: Eye for an Eye's assumed names are not really important unless they explicitly are. If two last names are the same, you're looking at family; otherwise, all those people are unrelated to each other or canon characters.

Half this chapter was built on headcanons, fan theories, and wiki information. Pretty sure a lot of this will be invalidated when canon gets around to it; don't care :3

...Probably not going to continue this without a lot more inspiration and actually reading the manga, but I 'like having the option open.
