You are Katsuki Bakugo's sibling, you two get along most of the time and mostly causes mischief in the house when you were kids

it was a normal day in UA. The class was being chaotic as usual before Aizawa came in

Aizawa: "Alright you waste of space... We will be having an Activity tomorrow.. Since Nezu couldn't find another way to amuse himself.. You'll be bringing your sibling to school.."

Bakugo: "Tch.. What if I don't want to?"

Aizawa: "then you have no grade"

Deku: "what if you don't have a sibling, Sensei?"

Aizawa: "not my problem."
