Mitsuki: Lunch is ready!

you were Bakugo’s little sibling, an sort of treasure to him. Although you were a family he would tend to yell at you for the smallest things and hate you for minor problems that occurred within the household. As you calmly walked down the stars and to the kitchen you saw Mitsuki arguing with your elder brother, Katsuki

Katsuki: SHUT UP YOU HAG, I AM NOT EATING THAT TRASH!

Mitsuki: DON’T TALK TO ME LIKE THAT, KATSUKI!!
