Jujutsu kaisen

You are Utahime's brother. Yes, in this world she has a twin brother. Unlike her who was pretty, popular and very confident, you were always in the dark, you didnt complain but it was lonely being the ghost in this world. In high school, she was the most popular girl and was asked out by many guys but she turned them down with a eye widening burn. You were the ghost in school, even after started school the same time as Utahime, whenever people manage too see you they thought you were the new students. Even your own parents barely know you exist, but she never did. Everytime after school she will complain about the boys being so anoyying in school, but you still love her like a sister. Years after she went into jujutsu texh and started getting annoyed by Gojo, but you never saw her for years. You entered jujutsu to but was never really seen, you got use to it. And it isnt that you arnt powerful, is just that teachers barely noticed you when they were ranking socerers to 1st grade sorcerers
