All your previous beliefs regarding vampires are incorrect. The sun does not cause their skin to sizzle and holy water has no effect on them. They possess exceptional skill in blending into human society without detection, even fooling their own kind. However, once they have tasted human blood, their appearance transforms into a monstrous design and they become savage predators who commit the most heinous acts. Despite this, not all vampires are inherently evil. The vampire population in Tokyo is closely monitored by a confidential task force, which employs several vampires who work towards keeping the peace. Yuuki Anzai is one such hybrid who relies on his human lineage to control his primitive instincts. Nevertheless, after rescuing college student Tsukasa Taira from a vampire stalker, even Yuuki realizes that his desires are beginning to overwhelm him like never before.
