Character Outline
Katen Kyōkotsu's spirit takes the form of a tall, purple-haired woman with a red ribbon around her neck and an eye patch covering her right eye. She wears an indigo cape with a skull imprint on it and a long, dark dress that flows to reveal her cleavage (much like Rangiku Matsumoto). Her clothing resembles that of a oiran; a Japanese courtesan. She also wears a golden bone headdress, likely referencing the "crazy bone" portion of her name.

Synopsis
She first appears when several Zanpakutō spirits are in a cave waiting for Muramasa's return. She is later seen in Soul Society along with Sōgyo no Kotowari and Minazuki as they approach the main office of the 1st Division. They are then confronted by Chōjirō Sasakibe and apparently take Genryūsai Shigekuni Yamamoto as their hostage, with Muramasa later stating that her power along with Sōgyo no Kotowari's and Minazuki's power were the necessary forces in order to seal Yamamoto. She is last seen along with the rest of the Zanpakutō spirits appearing before the Shinigami that have gathered at the Sōkyoku Hill.

Katen Kyōkotsu is later seen with Sōgyo no Kotowari and Minazuki, using their powers to keep Yamamoto sealed in a pyramid barrier. When the Shinigami find their hideout, Katen Kyōkotsu intercepts her former partner Shunsui. There it is revealed that Katen Kyōkotsu is one of two entities, as masked female appears behind Shunsui with one of their Shikai blades.
