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.

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.

When Akira runs away from the office over a trivial dispute, he unexpectedly bumps into his long-lost brother, Yui. Akira is delighted, but Yui behaves strangely, as little by little, the events of the past in their snowy home village are unraveled.

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!
