Tsujidou

Tsujidou is Suitengu's right hand man and accompanies him wherever he goes, often as a personal attendant. His Euphoria power is super enhanced olfaction, allowing to smell his enemies miles away (unlike most Euphorias, Tsujidou does not require a physical transformation to be able to use this). He doesn't reveal himself as a Euphoria until the last episode while fighting Ginza, in which he transforms into a large wolf. Along with Makabe, he was abused by local Yakuza years before and saved by Suitengu.
