Danjou was a large man with pale blue eyes and short blonde hair that's shaved on the sides. He was usually shown wearing a white sleeveless keikogi and a dark belt. 

Danjou was an upright and honorable man. Not liking the Darwin's Game's system of killing, he used his special privilege he earned from an event to set up a martial arts battle system that the clan could use instead of actually killing people.

His Sigil, Wall Iron, allowed Danjou to make his skin harder than tungsten.
