Yakuza Apocalypse

In the ruthless underground world of the yakuza, Kamiura is the legendary boss of the underlings. He is rumored to be invincible, but in truth is a vampire with superhuman powers. Kamiura's most loyal underling, Kageyama, is seen as weak by the rest of the gang due to his sensitive skin that can't be tattooed.  When assassins aware of boss Kamiura's secret arrive from abroad, he is given an ultimatum: return to the international syndicate he left years ago or die. Refusing, an assassination attempt is made against Kamiura and he bites Kageyama, passing on his vampire powers to the unsuspecting yakuza.
