Toshinori blinks. What . . . was he just doing? He clicks his teeth. Something’s . . . wrong . . . here.
A massive object thuds into the ground next to him, and he darts away; tucks himself into the nearby alleyway and peers back into the street.
It’s . . . people. Giant people walk along a giant street, carrying giant handbags and giant children. On the sidewalk lies even a pile of giant clothes. The villain must have made everything big!
“Bunny!” shouts one of these giant children, and they stretch massive arms toward Toshinori and stomp toward him.
Toshinori runs again. He squeezes himself behind a dumpster, and skitters away on the other side.
He thumps his leg and takes a moment to breathe. Something is very wrong here. He tries to pull his phone from his pocket, but struggles to lift his paw off the ground.
Toshinori blinks. Paws?
He twists his head, looks backward at his own body. His tiny, furry body. A fluffy tail sits near his butt, and he can feel his ears twitching.
Well. It appears the great All Might has transformed into a bunny.
This is fine. This is so fine.
Toshinori hops back toward the street and peers around. Yes, he remembers where he is.
Unfortunately the nearest source of help is . . .
Toshinori shudders. Maybe he’ll get lucky, and the hero in question won’t be around.
Feet larger than Toshinori’s whole figure stomp down the street. Toshinori inhales. A quick dash ought to do the trick.
Toshinori zips down the sidewalk, weaving around pedestrians. He just needs to get around this block, then across the intersection, and—
He’s squished. He’s squished. Toshinori is squished. A foot hooks onto his tiny form, and he skids across the sidewalk, and then a massive torso is smooshing him into the pavement.
“Gah!” screams the person on top of him.
Toshinori squirms, wriggles his way out from under his assailant.
“Nii-san?” comes another voice. “Did you just fall on a bunny?”
Toshinori zips once again.
“I think it’s okay,” says another voice.
Toshinori hops along the sidewalk until he reaches the intersection. The light is . . . yellow.
Toshinori blinks. That is not a typical colour for a pedestrian light. Maybe the display is broken . . . Well, the lit up image is of the standing-person on the top half, so that’s the red light, yeah? And when the walking-person on the bottom half lights up, that means go.
Toshinori thumps his leg. The lights tick tick tick as he waits. Massive cars whiz past, rumbling the ground beneath him.
Toshinori will never take his size for granted again.
Finally, the light switches to blue, and the people around him start to cross. Toshinori zips along.
“Wow, that rabbit knows about cross walks,” someone comments.
Yeah, because Toshinori is a person transformed into a rabbit. Of course he knows street safety.
Toshinori reaches the other side safely, and takes another moment to breathe. This is it.
Oh lord, what if they don’t recognize him? What if he hops into the agency, and they toss him out? Or they send him to an animal shelter? Or they EAT HIM?! Some people eat rabbits, right?
Toshinori’s leg thumps again. Then he hops up to the door, and presses his front paws against the glass.
The door, of course, doesn’t budge.
Toshinori bounces against the glass. A secretary sits at the desk inside. Just look up. See him. Help him.
Then, the person he dreads steps into the lobby. Speaks with the secretary a moment, then spies the panicked bunny at the door.
Toshinori gulps.
Mirko’s mouth widens into a grin, and her hands clench into excited fists. She likes her teeth and walks over to the door.
Toshinori stops pattering against the glass and sits patiently.
Mirko opens the door, and Toshinori hops in.
“Why hello there little bunny.”
Toshinori stares at her. Wills her to understand the pained human mind in his eyes.
Mirko bends down and scoops him up. “What are you doing here in the middle of the city?”
Toshinori clicks his teeth. It’s me. All Might. I’ve been hit by a transformation quirk and need help.
“You’re so cute! Don’t worry little bunny, we’ll find your owners.”
Toshinori is his own owner, thank you very much.
Mirko holds him by the middle, and Toshinori yelps. She pokes at his neck and sighs. “No collar. I’ll take it to a vet to see if it’s microchipped.”
Toshinori wiggles. I am not microchipped!
Toshinori clicks his teeth. There must be a way . . .
He pauses. Taps his teeth again. That’s it! He clicks his teeth purposefully. Three times fast, three times slow, three times fast. An international code for SOS.
Mirko’s brow furrows. “Aw, is bunny nervous? Was something chasing you maybe?”
Toshinori growls and pathetically flails a paw. He tries again. Three short clicks, three long clicks, three short clicks.
Then Mirko grins. “Hot damn, this bunny speaks morse code!”
Y.E.S. Toshinori clicks out.
“Yes,” Mirko interprets. She turns to the secretary. “Can you jot this down?”
“Yes, ma’am,” the secretary responds.
Toshinori contemplates his next words. Something short. Concise. To the point.
A.L.L. M.I.G.H.T. he clicks.
Mirko raises an eyebrow. “All Might?”
I. A.M. Toshinori adds.
Mirko’s head slowly turns to the secretary, who nods at her.
Q.U.I.R.K.
“You are All Might, transformed into a bunny by a quirk?”
Y.E.S.
And Mirko bursts into laughter. She brings Toshinori close to her chest, and he yelps in claustrophobia. Her fingers press around the back of his head and over his tail and his belly is pressed into her breast and oh how he hates the boisterous bunny hero.
“Well, All Might, let’s figure out what happened to you.” Mirko plops him down on the desk.
The secretary speaks up: “I’m searching the quirk registry.”
“Thank you, Oye-san!” Mirko bends over to level her eyes with All Might’s. “You got anyone you want us to contact?”
M.I.D.O.R.I.Y.A. he clicks out.
Mirko raises an eyebrow. “Green? . . .”
All Might thumps his leg. D.E.K.U.
“Deck? Oh, Deku, that UA student!”
Y.E.S.
“You have his phone number? Also why are you calling a child of all people?” She leans right up to Toshinori, nose-to-nose. “He your kid, or somethin’?”
Toshinori’s ears flatten to the back of his head. He opens his mouth, but doesn’t know what to click. He growls instead.
Mirko chuckles. “I’m just teasing you.” She bops a finger against his nose, and Toshinori recoils. “Anyway, you got a phone number?”
Yeah, Toshinori has Midoriya-shounen’s number memorized. He clicks his teeth together to convey it.
The secretary types the digits into her phone, and it rings.
Toshinori’s nose twitches. What if he doesn’t pick up? It’ll be an unlisted number. . . . He leans forward on his paws.
“Hello?”
Midoriya-shounen!
“Hi,” Mirko says. “This is pro hero Mirko. Am I speaking to Midoriya?”
“Mirko?!” the boy exclaims. “YES I AM MIDORIYA.”
“Fantastic. It looks like I’ve found your rabbit.”
A pause. “Rabbit? I’m sorry Mirko-san, but I don’t own a rabbit . . .”
Toshinori thumps.
“This rabbit claims he’s All Might and been hit by a quirk.”
“All Might?!”
“He’s been talking to me in morse code. Think you can swing by my agency? We’re checking the quirk registry right now to try and figure out what happened to him.”
“I’ll be right there!”
The phone clicks off.
The secretary speaks up. “I found a match for the quirk.”
Toshinori’s ears perk up.
“There’s an Umemoto Mizuko, a five year old girl living in a nearby apartment building. Her quirk is called ‘Bunnify’, and it can turn the people she touches into rabbits.”
“How long does it last?” Mirko asks.
“Doesn’t say. She’s young, so they might not have updated the registry with any details they’ve discovered. I’ll reach out to the family now.”
“You’re the best, Kiki-chan!” Mirko praises. Then fingers slink again under Toshinori’s soft fluffy belly, and he’s lifted into the air. “While we wait, we can have a little fun, Bunny Might-chan!”
Toshinori wiggles in fruitless resistance.
Mirko carries Toshinori through a hallway and into her nap room.
At first, Toshinori smells threat. His body clenches up in terror, before he remembers that he’s at a pro hero agency, quite literally in safe hands.
Inside the nap room, a large white rabbit maniacally jumps across the floor, twisting in the air. Another, smaller brown rabbit chews a cardboard tube.
The large rabbit nyooms to Mirko’s feet and rams its body against her shins.
“Welcome to the bunny room!” Mirko says. “I can clear this big boy out of here if you want some privacy. Thought you might like to enjoy some of the luxuries of bunny life!”
Toshinori’s ears twitch. In this nap room is a giant cushy bed adorned with cushions. Along the wall runs a series of running and climbing planks.
Mirko steps further into the room, teasing the large rabbit with her foot.
The small rabbit locks beady eyes with Toshinori and ceases chewing.
Toshinori stares back.
Is the rabbit vigilant at the sight of an intruder? Or does it somehow know that Toshinori isn’t really a rabbit? His fur is rather yellow, but perhaps that’s an effect of his altered sight. Maybe he’s actually white? Or a more blonde colour?
Mirko lays him on the bed.
Toshinori kneads his feet into the cushion. Ooh, that’s a nice sensation.
Mirko scritches a finger behind Toshinori’s ear, and he leans into the touch, before pulling away. Oh my . . .
He’s never been a super touchy person, but his newfound . . . instincts sure seem to be tempting him.
Mirko rubs a hand over the top of his head, along his ears, then down his body, and he melts. Ooh, he likes touching.
Toshinori happily clicks his teeth as Mirko strokes him. Around the ears, over the shoulder blades, under his chin.
Toshinori deserves a nice break from being a human.
Unfortunately, he sinks a little too deeply into her touch. Forgets himself just a little too much, and before he knows it, he can feel the pleasure pooling in a specific, very inappropriate body part.
His leg thumps against the mattress, and Mirko’s hand lifts. Toshinori’s head instinctively follows, and he has to tense his hole body to force himself to stop.
He cannot—cannot—have a—a boner in public!
“What’s wrong, Bunny Might?”
His dick throbs, and he lowers his body just slightly to the bed. Putting some pressure on it will help alleviate the tension.
His growing erection sings at the contact, and Toshinori whimpers pathetically as hip hips twitch into a small thrust.
And Mirko giggles.
And that’s right, she’s /there/. She’s Mirko, number 6 pro hero.
Toshinori trembles. He can’t . . . let her see . . .
“I guess you aren’t neutered,” she says. “Obviously.”
Toshinori thrusts again against the mattress, and god, he hasn’t felt this virile in years. If only he had hands, he could . . .
Toshinori shakes his head. No, he can’t—!
“Let me help you, bunny.”
Please.
Toshinori is scooped up with one hand, and he wriggles in horny desperation. Mirko’s finger presses right up against his dick, and he ruts against it.
“It’s so tiny!” Mirko laughs.
Toshinori digs his teeth into her finger.
“Okay, okay!” Mirko brushes gently up the length of his little bunny dick, pressing it to his belly.
His skin burns at the tease. She pinches his dick between two fingers, gives it a little squeeze, and that’s all he needs. His balls tighten. Then he spurts. The endorphins bleed through his muscles, and for the first time in ages, Toshinori finally, truly, relaxes.
“All Might?” comes the voice of Midoriya—his boy—and All Might leaps out of Rumi’s hands, lands on the floor, and scurries under a blanket in absolute mortification.
“Oh fuck,” comes Mirko’s voice. “Kid, how long have you been standing there.”
“Muh-m-muh—”
Toshinori rubs his face roughly into the blanket. He wants to DIE.
“You’re Midoriya, right?” says Mirko. “I’m Mirko.”
“M-m-m-Mirko.”
“Yeah, that’s right. You’re here for All Might, yeah?”
Midoriya’s teeth chitter in lieu of a response.
Toshinori wails.
“W-why,” Midoriya stammers, “w-were you t-t-t-t-touching All Might l-like th-that?”
Noooooooooooooo.
“Well, uh . . . As you know, he’s been turned into a rabbit by a quirk.”
And then . . . Toshinori thinks he might hear the schink of . . . One for All?
“Rabbits are . . . very sexually active.”
“DID YOU TAKE ADVANTAGE OF ALL MIGHT?!”
Oh fuck. Midoriya’s quirk powers up, and Toshinori shoves his head out of the blanket, desperately clicking /no no no/ with his teeth.
“Oh fuck,” Mirko says, “No, kid, he just got a boner—”
Midoriya’s eyes glow. “Did you get consent?!”
Toshinori jumps out of the blanket pile and bounds up to his boy. Oh my, Midoriya-shounen, please calm down.
Midoriya’s hands reach down to scoop Toshinori up protectively.
And then, Toshinori is falling, as if his skin has been replaced by a weighted blanket. He falls falls falls, but he’s standing, arms raised and knees buckling.
“All Might!” Midoriya shouts, and he’s smaller now.
Toshinori blinks. Pulls his arms down. He’s human again!
Oh, he’s human again! He hastily lowers his arm to his groin to cover himself.
Midoriya twitches.
Toshinori opens his mouth—oh, how he loves human anatomy. “Everything’s fine my boy. I’m sorry to have traumatized you so. Please . . .” leave?
“All . . . Might . . .”
Mirko’s hand is suddenly in front of him, holding a blanket. Ah . . . yes. He takes the item and starts to wrap it around his waist like a towel.
“All Might are you sure you’re okay?”
“Yes I am . . .” Now as tense as he was before the orgasm? No, no, he can’t think such thoughts in proximity of his boy. “I am fine, Midoriya-shounen. Thank you for your concern. I’m sorry to have exposed you to . . . I’m so sorry. . . .
Midoriya nods hesitantly, and then swiftly absconds.
Once he’s out of the room, Mirko flashes Toshinori a grin, to which Toshinori bites his lip.
Maybe . . . if this should happen again . . . he will not call Midoriya . . .
