Shitari of the Bones

Shitari of the Bones (骨のシタリ Hone no Shitari?, [δ]) is the Gedoushu's strategist, a squid-headed demon armed with a shakujō who awaited for Doukoku's revival. Shitari sees humans as mere specimens for his research, uncovering means to overflow the Sanzu River. He also possessed texts from the Shiba House which he used to learn about the seal placed on Doukoku. Though he warns Doukoku not to trouble himself with the Shiba House's sealing character so not to attract attention from certain Ayakashi, Shitari recruits Isagitsune in an attempt to slake his curiosity on what the sealing character is. He later recruits Oinogare in an attempt to re-open a well the Gedoushu used in the past as their base of operations by sacrificing nine maidens, formally introducing himself to the Shinkengers as a result.

While Doukoku is in a vulnerable state struggling with his surging power, the rogue Ayakashi Gozunagumo bullies Shitari into extorting the sealing character from Shinken Red. Despite poisoning Takeru, Shitari fails to get him to reveal the sealing character due to the combined interference of Shinken Gold and Juzo. When Doukoku revives and punishes Gozunagumo, Shitari freely confesses that the one thing he values above Doukoku is his own life. Doukoku, amused by Shitari's honesty, forgives his underling's treachery. During the events of Kamen Rider Decade episodes 24 and 25, Shitari witnesses Daiki Kaitoh stealing the Ika Origami and sends the Ayakashi Chinomanako to investigate the otherworldly Kamen Rider Diend, causing the chain of events that would doom their world. When Akumaro arrives, Shitari expresses a great deal of distrust over the mysterious Gedoushu and not as much shocked when his impression of him was accurate yet was powerless to do anything against him as he realized Akumaro's intentions. After Dayu returns, Shitari decides to kill off Takeru, only to learn the truth behind him and the Shiba House's true leader and giving up half of his life in an attempt to speed up Doukoku's reawakening. He remains on the Rokumon Junk during Doukoku's final battle with the Shinkengers, going down with the ship as it sinks in response to its master's death.[4] Shitari is modeled after Fukurokuju (福禄寿?) and Jurōjin (寿老人?).
