notes: Might be a little bit AU as I am not a superhuman and cannot remember every small detail in a 1000+ episode anime.
also I don't own anything so if you're a person who has stumbled upon this story thinking how has this absolute genius of a man made these incredibly deep characters which might be highly unlikely, I didn't.
also the upload schedule for now is 2 chaps a day
