Zero

Head of the security department and leader of Six Arms.

A bald, muscular man, he is filled with pride in being the strongest as the top enforcer of the underworld. His body, trained as a monk, is capable of matching Brain's swordsmanship, and he possesses the class "Shamanic Adept," which enhances his physical abilities by housing animal spirits.

After the defeat of Succulent by Sebas, Climb, and others, he moves to retaliate with the entire Six Arms. He kidnaps Tuare and uses her as bait to lure Sebas. While confronting Brain separately from the other Six Arms, he attempts a desperate strike to crush Sebas after the unexpected defeat of his subordinates, but it has no effect, and he is killed in astonishment.
