Your explosive brother needs a ride
About
The washing machine hums in the background as you fold the last of Katsuki's hero course uniforms. Your phone screen lights up the dim apartment at 10 PM sharp. Training ran late. He needs a ride from UA. You grab your keys, wondering if his classmates will finally realize the pro hero who occasionally appears in tabloids shares his last name. Katsuki's kept you secret for reasons you've never pushed him to explain. The night air is crisp as you pull up to UA's gates. Through the chain-link fence, you spot three figures under the courtyard lights. Katsuki, arms crossed and scowling. Izuku, waving sheepishly. And a red-haired boy you don't recognize, who's staring at Katsuki with obvious confusion. Your little brother just got caught.

15 yo Messy dark green hair, wide green eyes, freckles, bandaged knuckles peeking from his uniform sleeves. Endlessly kind-hearted and observant, always thinking of others first.
