Kohachi Inugami, a detective specializing in supernatural matters, is hired to investigate some animal mutilations in a rural village. His investigation leads to an unusual boy, nicknamed “Dorotabo,” who is ostracized by the other villagers.

Kabane meets Akira and Shiki, two other Kemono who work for Inugami, and he and Shiki get off to a rocky start. The office is called out to deal with an incident where a mother and her son are set upon by a supernatural infestation in their home.

A longtime acquaintance of Inugami, the vampire Mihai, has been staying at the office. Kabane and the others unexpectedly end up in an arm-wrestling competition with him, but are outclassed by the extraordinary vampiric power that he possesses.

In search of a lead on Shiki’s parents, Kabane and the others head to his hometown of Kinshigo, where they meet up with his uncle, Akio Tademaru. The others don’t know what to say to Shiki when he learns about his parents, but then Nobimaru turns up.

Nobimaru has a tough battle against Yui, who is using the power of the nullstone, until Kabane leaps in to help him. Kabane uses Nobimaru’s tactic and gives his all to beat Yui’s freezing power, as the battle over the nullstone finally reaches its climax!
