Kabane, Shiki and Akira embark on a dangerous mission set up by Mihai, breaking into a company controlled by a trio of kanonba (mosquito Kemono) sisters to investigate it. When discovered, they must fight it out, but something comes over Shiki.

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.

Shiki corners the man who tormented his mother. However, at the last moment, he is attacked by a pack of Kemono and finds himself in a pinch. Separated from Inugami, Kabane and Shiki are surrounded, and must confront the pack of Kemono themselves.

Kabane and the others try to bring Akira home from the ice castle, but are stopped by the power of Yui’s nullstone, and Akira is overcome with shock at the turn of events. Meanwhile, Inari and Nobimaru secretly go into action to claim the nullstone.

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!
