Kyōkotsu

is the first of the Shichinintai to appear in both the anime and manga, he is also the first sign of the revival of the Shichinintai. He is presumably the weakest of the seven, despite his abnormal size. He has an appetite for human and yōkai flesh.

Also, because he devoured many yōkai, his body size became abnormal. He wields a giant spikeless flail, with the ball being about the size of an adult human, although because he devoured many yōkai, 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 Kōga's wolf tribe and proceeds to die by Kōga's hand. His Shikon shard was located in his forehead, where Kōga pulled it out. He also had a short meeting with Kohaku shortly before his death; Kyōkotsu attempted to take Kohaku's jewel shard, but to no avail.

Appearance
Kyōkotsu wears a red skirt with white timing on the bottom. He has a yellow sash tied like a belt around his waist. He wears blue chest pads as a form of armor on his shoulders he has two black pads, he also wears a black headband upon his head to hold back his short green hair.

Abilities
Due to his large size, Kyōkotsu possesses a great amount of strength & endurance, even being able to create a deep crater when he punches the ground. He is also skilled with a flail (which has been made to suit his large body). He is also able to survive having his body being in abnormal angles that would normally be lethal, this might be due to his jewel shard.

Trivia

 * Unlike the other members of the Shichinintai, Kyōkotsu'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 Kōga twirled Kyōkotsu'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 means Power, referring to his great size and strength.
