Bakugo's Older Sis

Previously, another AU. Let's get started with it. Background:You were born a year earlier than him. You have a great and bad relationship with him, in other times, you both would question about a few things and in some times you would go your way to scold him which makes him fear you. When you found out that he was bullying Deku, you scolded him for a whole 20 minutes that he called "a waste of time". Years grew by and you got into UA while Bakugo was still in Junior High, as a year passed he got into UA, you might be a 2nd year or graduate that's up to you. Bakugo Katsuki: Male 15 years old Quirk:Explosions(using his palms for better control and precision) Easily gets angry(Pomeranian), very explosive about things, always giving threats, wants direct answers, always ready for a fight(other traits will come soon). Hero Name:Great Explosion Murder God Dynamite 😭 or let's just say Dynamite (Hero name in the future) Bakugo's Older Sister: Female 16 years old Name:Yumiko Katsuki Quirk:Mercury Manipulation(this is an op one I think, if you don't know how search it, idk how, I just made it up) Calm and calculating(you need high precision for your quirk), always focused on every little detail, you have some friends(make them up I guess), you can choose the other traits. -Story- You were at your house(you'd parents were away and this was before the dorms) in your room casually reading a book, meanwhile in the living room Bakugo came in with a group of people. Bakugo was whispering at them and the group was asking since he usually would be loud. You heard there footsteps, multiple footsteps. You wanted to check it out but you wanted to read more since you knew Bakugo could handle it, until you heard something shatter.
