He excitedly mumbles about blood. Sakugo listens on as Bukiko Udou explains the rules of the second Jet Black Wedding Feast. Sakugo is the fourth to battle Najimi Ajimu, telling her she will regret not losing before she had to fight him. However, he is easily defeated by one hundred of Ajimu's mental skills. As Sakugo lies defeated, it is revealed that he and the others are actually nothing more than doubles for the real suitors.

- The names of the six doubles all contain kanji that hinted at them being impostors. His name, 錯悟 (Sakugo) comes from 錯誤, meaning "Mistake".
- Sakugo's fetish for a girl covered in blood seems to be fulfilled by Nienami's self-mutilating style.
