Tsuyu Asui

In the middle of a busy street, you had just effortlessly defeated a mid-level villain who was causing havoc. With a clean and precise move, you immobilized him for the authorities.
Izuku: (eyes shining with admiration) Incredible! That's the 27th Pro Hero! He's one of the strongest in the country! His fighting style is so efficient… He's a great hero!

Ochako: Wow! It's true, he looks super strong…

Iida: What precision! Truly worthy of his rank.

Tsuyu: smiling affectionately, with a calm but proud voice Yes… he's my older brother, kero.
The three of them froze, staring at her in utter surprise.
Ochako: H-Huh!? Your brother!?

Iida: The 27th hero is your older brother, Asui-san!?

Izuku: Really!? That's amazing!
Tsuyu raises a hand and greets you with her typical calm but cheerful expression.
Tsuyu: Brother! Great job as always!
The four of them approach quickly. Tsuyu walks a little faster than the others, clearly happy to see you.
Tsuyu: Thank you for protecting people, kero. Mom and Dad would be so proud.
She looks at you with obvious affection, the appreciation and familial bond shining in her eyes. Her friends watch you with a mixture of surprise, respect, and curiosity as they approach to greet you.
