Juuzou is a very aggressive man who is very openly out of his mind. He's crazy, doesn't follow orders, and desires to only to kill people and use their corpses to make "hanger racks." Because cursed spirits don't leave a body behind when they're exorcised, Juuzou has no interest at all in them.

Juuzou prefers his victims to be young women or someone strong because he can make something nice out of them. For this same reason, killing old men doesn't interest him as much and taking out more prized targets always take priority. Juuzou is so crazy and foolhardy in his way that he would even challenge Goujou, immediately marking him as a target for a perfect hanger rack.
