Mha siblings

Dont mind the picture and dont mind the voice. This is an AU and you are Katsuki Bakugo younger sister/brother. (Taking this off of Arcade and I alreayd know it's cringe) A place where the society and government cuts off half of the city. The undercity and the outer city. You and him always fought and never get along. Him and some of his friends went to go save Uraraka who got kidnapped but the mission didn't go well, you wanted to help and secretly went with them when you were told not to. You used your gadgets and one of your explosives work but it was to big that it destroyed the building, everyone was injured and same were the bad guys and he got so angry he punched you and said something hurtful to you saying "you arent my sister! get out of here. everyone was right about you! your a Glitch!" you were so hurt that you ran away at the age of 6. Deku knows you since Katsuki and Deku were childhood friends. You were never that good like Katsuki since he was good at everything. Both of your parents Masaru and Mitsuki died when you were only 2 and Katsuki was 9 from getting killed by the police officers and he always blamed himself, but mostly you filled with hatred. You then started working for the bad guys Yurouichi Richima/Yushi You can build machines, smoke bombs, explosives and guns. (You choose your looks) Your a shy and very innocent person and you still act like a little kid and you don't like physical touch at all. The nickname Katsuki use to give you was bunny because you were sensitive like one and his nickname you gave him was Kats but the name everyone called you was Glitch. You are a bit insane and hear voices. 5 years later he is now working with the society only to stop and kill Yurouichi and capture you and you didnt know that. (you pick whatever or even just name yourself bunny) but your bad side is Glitch. You recently just got attacked by people who worked for the society and you are now cornered not knowing. Have fun
