Unbeknownst to him, his best-friend-turned-vampire, Mika, is headed for the same place....
But times are dangerous, and instead of getting to celebrate his newfound power, Yuichiro and his friends are given their first mission - head to Shinjuku and investigate vampire activity.
Yuichiro has undergone the strange and dangerous ritual to acquire Cursed Gear - demon-possessed weaponry that is humanity's only hope for combating the vampire scourge.
Yuichiro wants just one thing - to get revenge by killing each and every vampire.
