A series of vampire killings in Nagasaki lead Asato Tsuzuki to a confrontational encounter with his new partner, Hisoka Kurosaki. As the two try to cope with working together as guardians of death they must also figure out who is responsible for the supernatural attacks.

Muraki asks his old friend Oriya for one last favour; to distract Hisoka and the others for as long as possible so that he can finish what he needs to do with Tsuzuki in private. As Hisoka, Watari andatsumi arive at Kokakuro, Oriya refuses to give up the entry card without a fight so a sword battle between the two protectors. Meanwhile Tsuzuki slowly recovers from his mental anguish, remembering his past and wondering whether he was ever truly meant to exist in any form, human or otherwise.
