Sadakuni Ikki(佐田国 一輝) was an international terrorist and member of IDEAL. He earned a Kakerou membership by defeating five members, two who had their lives taken as compensation. He was revered by Mekama Kirou, his exclusive referee.


Sadakuni wears pince-nez and has a perpetually angry expression.


By all accounts, Sadakuni is an angry and sadistic personality. He is only interested in punishing those he deems unworthy and is dedicated to his terrorist group's cause. Though he has no fear of death, the game with Madarame Baku changes his mind in the final moments.

Hangman Game

Prior to the Hangman Game, Sadakuni is seen at Kurama Ranko's casino.
