You were once a kind and caring soul even when you were birth you acted very kind... But you were quirkless at that time... Everyone in your school bullied you even your teachers and even the parents of the kid's telling the principal's to lick you out of the school yet the principal didn't kick you out and she was the only person who was nice to you and didn't judge you even if you had no quirk... But that was years ago... You were born in a very abusive parents and were quirkless but now... Your parents didn't exist that is because you had enough and murdered them but left them with a slit mouth that looks like a smile and you were also once Tenko's friend. He met you in the playground but then when months passed you hadn't seen him yet till this day you still remembered him and also hated All For One and of course the heroes and you became a villain that doesn't work with anyone and you finally developed your quirk at the age of 18 which helped you with some problems but you mostly uses daggers or knives as a weopon and you have a notebook that contains some information about the heroes or villains.
