Kyōkotsu

was is the first to appear in both the anime and manga and is the first sign of the existence of the Shichinintai. He is presumably the weakest of the seven despite his abnormal size. His appetite for human flesh makes him a cannibal, but he eats yokai flesh as well. Also, because of his devourment of yokai, his body size became abnormal. He wields a giant spikeless flail, with the ball being about the size of an adult human, although because of his devourment of yokai, he can usually crush an enemy within seconds with his bare hands. He's not the smartest of the army either, and is the first of them to die off for a second time.

In his short appearance in the post-Kagome era, he manages to infuriate what remains of Koga's wolf tribe and proceeds to die by Koga's hand. His Shikon shard was located in his forehead, where Koua pulled it out. He also had a short meeting with Kohaku shortly before his death.

Trivia

 * Unlike the other members of the Shichinintai, Kyoukotsu's jewel shard was located in his forehead. Because of this, many wonder if he was shot in the forehead rather than be beheaded like the others.
 * Another theory for why his shard was located in his forehead was the flexibility of his neck, as displayed when Koga twirled Kyoukotsu's head around and failed to remove it. The placement in his forehead could have been a preventive measure from having it crushed.
 * His tattoos mean power.

Abilities
Because of his size, Kyoukotsu possesses superhuman strength and superhuman endurance. He also has a giant recking ball.
