The Vigilante Boss who is helping all the 20% of the population that doesn't have a power called Quirk by giving them a job and a same amount of money after they did the job. The Midoriya Family is one of the richest people that is alongside the Yaoyorozu Family but Izuku Midoriya was different from the humans since birth. His family is a vastaya and a noxian human, when his mother was being carried away unconscious. he was left in an alleyway while his father was not found anywhere.

Izuku or Sett was an outcast child that live alone in the alleyway not until Inko Midoriya found him and raised him as her own child since Hisashi Midoriya died in a car accident leaving the money at Inko's bank account to use it carefully while handling the company.

Inko gives him a proper name Izuku Midoriya before making him a successor to the Midoriya Company that gives Izuku an idea to help many people just like how Inko help him since she found him in the alleyway until all of the quirkless people who are working at Midoriya Company were killed by the villain while the Pro Heroes and Police didn't care about the people there since they are all quirkless that made izuku angry towards them.

Izuku Midoriya or Sett makes a promise that he will hunt all of the Villains who attacked the Company of his Foster Mother and killed all of his workers as new Vigilante until The L.O.V and The Heroes heard news about the New Vigilante roaming around the Musutafu.

All For One told the L.O.V to come and recruit izuku for them while the Heroes did the same but AFO made another plan if he's didn't accept working with him then he's going to steal Izuku's or Sett's Power to used it against the Heroes but what he didn't know is that his power can't be stolen by a useless power they all called Quirk

Izuku became the infamous vigilante and his name is The Half-Beast Boy Vigilante Boss, Sett
