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.
