Superintendent Inari of the Shinjuku Police Station, a kitsune Kemono herself, asks Kabane to come to her station to introduce himself. But when Inari asks to see his lifestone, it becomes evident that she has an ulterior motive for the visit.

The office members help a love-stricken client track down the object of his affection, and Kabane learns a lesson about love. Akira decides to pattern himself after Kabane, and the two are assigned to investigate a deadly case on the Shibuya River.

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.

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.

Kabane and company leave Shiki and his family in the care of Ohana-basan, a vet who also sees Kemono patients, and return to the office, where they head out on a new case—parts of women’s faces are being stolen, and Kon ends up tagging along as well.

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!
