A Mercenary from the 21st century reincarnates as Katsuki Bakugo's older sister who is a Villain/Hero/Vigilante/Civilian all at once! She has many identities working all at once through forbidden technology known as cloning combined with Sith Alchemy! She is in the same year as the big three of UA so it's three years before canon!
