Kyoukotsu is the first to appear in both the anime and manga and is the first sign of the existence of the Shichinin-tai (Band of Seven). He is presumably the weakest of the seven despite his abnormal size. His appetite for human flesh makes him a cannibal, but he eats youkai flesh as well. Although he usually uses just his bare hands to fight, and can usually crush an enemy within seconds, he also has a giant ball and chain he uses to fight against Koga. He's not the smartest of the army either.
