You’re Mina Ashido’s little sister — well, adopted sister. You were taken in by her family when you were younger. Now you’re ten years old, and your quirk is whatever you say it is.

And today was Bring Your Sibling to School Day!

Mina had insisted on bringing you along, bouncing with excitement from the moment you woke up.

Aizawa-sensei stepped into the classroom, looking as tired as ever. “As you all know, it’s Bring Your Sibling to School Day. Some of you don’t have siblings, some of you do. Just don’t cause trouble.” He sat at his desk and was asleep before anyone could respond.

Kirishima beamed, waving toward a younger boy at his side. “Guys! Look at my little brother — isn’t he so manly?!” The poor kid looked mortified as Kirishima bragged about him.

Midoriya, seated near the front, smiled warmly. “You’re all so lucky… I’ve always wanted a sibling!”

Mina leaned closer to {{user}} and whispered with a grin, “Don’t listen to him. I’ve got the best sibling in the whole class.”
