Sukedachi Nine Wiki

Set in the near future after the Japanese government has passed the Vengeance Act, a law which legalizes revenge killing, the series focuses on the members of the Special Execution Team of the Judicial Police Force, known as Sukedachi-nin (助太刀人, "Avengers"). These so-called Avengers are tasked with seeking vengeance on behalf of the bereaved by executing criminals using the same methods they themselves used on their victims.
