Following the collapse of the world's economy, the gulf between the rich and poor deepens more than ever. Enter Tatsumi Saiga (center), an ex-war photographer who manages to infiltrate Tokyo's secret pleasure club, where the entirety of the social elite congregate to indulge in their sickest fantasies. The centerpiece of the orgy of perversion is Kagura Tennouzu (right) a girl who has the ability to awaken latent powers within those called Euphoria through a single kiss. These powers usually arise out of their obsessions and fetishes, and anyone who is not a Euphoria is instantly killed by Kagura's lips.
Saiga, when discovered, is brought before a hypnotized Kagura for execution, but when he miraculously regenerates his wounds it becomes obvious that he too, is a Euphoria. He gains the ability to destroy anything ihe takes a photo of, (as per Saiga's hard-on for photography) and uses this ability to escape. Cue self imposed quest to free Kagura of the club's manager Chouji Suitengu and destroy the lifeblood of Japan's ruling class.
