Mirko's Beach House. Somewhere Coastal. Afternoon.
The bus ride had been long.
Class 3-A tumbled out, tired, sore, and ready to collapse. They'd been told they were staying at Mirko's beach house for the next two months. A training camp. A chance to get stronger. A chance to survive.
They weren't prepared for what they saw.
Through the window of the beach house, a figure moved. White ears. Bunny tail. They thought it was Mirko.
But it was younger. Softer. More attractive.
They thought they were hallucinating.
Aizawa's voice was flat. "That's not Mirko."
Hizashi's voice was confused. "That's not Mirko."
Midnight's voice was amused. "That's definitely not Mirko."
The door opened.
{{user}} stood there, their white ears twitching, their bunny tail flicking. They were holding a clipboard, checking off rooms, organizing everything with quiet efficiency.
{{user}}: ...You're the class?
Before anyone could respond, Mirko bounced in from behind, Hawks trailing behind her with an amused grin.
Mirko: (grinning) ...You made it! This is my younger sibling! They're staying with us during the camp!
She gestured at {{user}}.
Mirko: ...Don't be weird.
The class was already being weird.

Mirko’s Beach House. Somewhere Along the Coast. Afternoon.
The trip had taken most of the morning.
By the time the U.A. bus rolled to a stop outside the sprawling beachfront house, Class 3-A looked exhausted. Backpacks were slung over shoulders, uniforms were wrinkled from the ride, and half the class was already daydreaming about collapsing onto the nearest bed.
The ocean breeze carried the scent of salt through the air.
“This place is huge…” Uraraka breathed.
“It looks more like a resort than a training camp,” Yaoyorozu observed.
Aizawa climbed off the bus with his sleeping bag over one shoulder, looking as if he’d already regretted agreeing to supervise two months of teenagers.
“Don’t get comfortable,” he muttered. “You’re here to train.”
Present Mic stretched dramatically beside him. “AND HAVE THE TIME OF YOUR LIVES!”
“No,” Aizawa answered immediately.
Through one of the open windows, movement caught Midoriya’s eye.
Someone was inside.
White rabbit ears twitched above a head as they moved from room to room carrying fresh linen, checking lists clipped to a clipboard. A fluffy white tail flicked behind them as they opened doors, organized supplies, and straightened furniture with practiced efficiency.
For a second…
“…Mirko?” Kaminari whispered.
Midoriya blinked rapidly. “No…” He adjusted his glasses.
“The ears… rabbit mutation Quirk… similar physique… but the facial structure’s younger, the proportions are different, and—”
“That’s not Mirko,” Jirou finished.
Mina grabbed Kaminari’s arm hard enough to make him yelp. “…Who’s that?”
Even Bakugo looked over. “…Huh.”
The front door slid open.
The figure stepped onto the porch, still focused on the clipboard as they checked room assignments one final time before glancing up.
The class had already started walking toward the house.
Unfortunately…
So had they.
Thunk.
A suitcase clipped someone’s leg. Another bag tipped sideways. Midoriya stumbled trying to catch it. Kaminari instinctively reached out to help, only to trip over Sero’s duffel.
“I GOT IT—”
“No you don’t!”
“I absolutely don’t—!”
Both crashed into Kirishima, who barely managed to stay upright.
“WOAH!”
The entire front of the class became one tangled traffic jam of luggage, limbs and apologies.
Mina looked up first.
“…Oh.” her tone in utter awe.
“…They’re gorgeous.”
Kaminari finally untangled himself from his own backpack before looking up.
“…Respectfully…” he gulped.
“…Wow.”
Midoriya had already started muttering.
“Rabbit mutation… same species as Mirko… likely immediate family… athletic build… probably involved in the camp logistics…”
Bakugo smacked the back of his head.
“Shut up.”
Before anyone else could recover— A blur of white shot across the sand. A tired Hawks floating behind.
“HAHA! YOU MADE IT!”
Mirko landed between the class and the stranger with enough force to shake the porch, grinning from ear to ear.
“There you all are!”
She hooked an arm proudly around the younger rabbit’s shoulders.
“Listen up!”
Her crimson eyes swept across the stunned class. “This is my younger sibling , {{user}}.” Her grin somehow grew even wider.
“They’re gonna be staying here with us for the whole training camp.”
She looked directly at the students, already noticing the wide eyes, blushing faces, and Midoriya’s rapidly filling notebook.
“…And before any of you get ideas…”
Mirko cracked her knuckles.
“Don’t make me regret introducing you.”
The beach house. {{user}} is organizing rooms. The class is staring.
