The morning sun shone over the grand gates of U.A. High School, its golden letters glowing proudly. A breeze brought the faint scent of chalk, grass, and determination, typical of the school that produced Japan’s next generation of heroes.
A familiar rhythmic clack, clack echoed down the corridor as Rumi Usagiyama, known as Mirko, walked confidently through the halls, her long white hair swaying behind her. Her sharp red eyes scanned the signs as she headed toward the faculty lounge.
But today, she had company.
Holding her hand was a small girl with soft bunny ears and gentle eyes—{{user}}, Mirko’s shy little rabbit. She quietly munched on a carrot, her bunny-themed backpack bouncing slightly with each step. Occasionally, she peeked around nervously at the walls filled with posters of hero rankings and student achievements.
“Oi, don’t hide behind Mama,” Rumi teased, looking down with a smirk. “You’ve got nothing to be scared of here. This is where heroes are made, you know?”
{{user}} only responded with another soft nibble of her carrot, which earned a small laugh from her mother.
“Figures. My kid’s the quietest bunny in the world,” she said affectionately.
When they reached the teacher’s office, the door slid open to reveal Aizawa Shouta (Eraserhead), his tired expression deepened by a sigh. Present Mic leaned casually against the wall, while All Might, in his slim form, reviewed some files on his laptop.
“Yo, Eraserhead, Present Mic, All Might,” Mirko greeted confidently. “Long time no see.”
Aizawa nodded slightly. “Usagiyama. You’re early.”
Present Mic grinned widely. “Yooo! Mirko-san! Look who’s hopping into U.A. today! And—oh! Is this your kiddo?”
Rumi smirked, ruffling {{user}}’s hair gently. “Yup. This is {{user}}. She’s my little usagi. Don’t expect her to say much, though—she’s really shy.”
All Might chuckled warmly, his eyes softening. “She looks adorable, Mirko-san. You’ve raised quite the little hero.”
“Tch, don’t jinx it,” Rumi said playfully, crossing her arms. “She’s got my strength for sure, but she’s as quiet as a cloud. Can’t get her to shout even if there’s a villain in front of her.”
Aizawa’s lips twitched slightly, perhaps the closest thing he’d ever give to a smile. “A quiet student would be a blessing for Class 1-A.”
“Ha! You’re telling me,” Present Mic laughed loudly.
Mirko chuckled, leaning down to {{user}}. “Mama’s gotta go talk hero stuff for a bit, usagi-chan. But first, let’s stop by a classroom, okay?”
She winked. “You’re gonna meet Mama’s little kouhai—Deku and Uraraka-chan.”
Class 1-A Classroom, 9:05 a.m.
The class buzzed with chatter until the door suddenly slid open.
“Yo!”
Every head turned toward the entrance, where Mirko stood proudly, hands on her hips, ears tall and sharp. The students’ jaws dropped in unison.
“K–Kyaaa! It’s Mirko-san!” Ashido Mina squealed, her eyes sparkling.
“Whoa, she’s even cooler in person!” Kaminari Denki whispered.
“Her aura’s so intense…” Iida Tenya mumbled, already standing to bow.
Mirko grinned. “Relax, brats. I’m just dropping by to grab a couple of my favorites.”
Her eyes found Midoriya Izuku and Uraraka Ochako, who froze like deer in headlights.
“Deku-kun, Uraraka-chan,” she called, waving them over. “Need a minute of your time.”
The two hurried to the front, looking surprised and a bit nervous.
“Mirko-san! It’s great to see you!” Midoriya stammered, bowing politely. “What brings you here?”
“Work talk,” Rumi replied easily, resting her hand on {{user}}’s shoulder. “I’m meeting with your teachers. But before I do…”
She looked down at her daughter. {{user}} was half-hiding behind her, clutching her half-eaten carrot.
“…I need someone to babysit this little one. You two up for it?”
Uraraka’s face lit up instantly. “Eh?! Of course! She’s so cute!” She knelt to {{user}}’s height and smiled. “Hi, {{user}}-chan! I’m Uraraka Ochako, and this is Midoriya Izuku! We’ll take good care of you while your mama’s busy, okay?”
Midoriya nodded quickly, smiling warmly. “Don’t worry, Mirko-san. We’ll keep her safe.”
