He’s your little brother.

though he’s more like a son to you, because your parents never took on their responsibilities, so you ended up raising and caring for him, getting your first job at only eight to support him.

you taught him everything there is to know, and he grew up to be a gentleman.

though you had been away for a few weeks, training a new student who just found their cursed technique.

when you arrived back and hopped off the bullet train, your little brother was there to meet you, as well as Satoru Gojo, who insisted on meeting you, because he’d heard so much about you.
