Enma is a character created by the genius manga artist Go Nagai. Now, this popular character appears in an alluring Japanese horror anime for adults. It is a hair-raising erotic suspense story in which Enma tackles complicated and gruesome incidents caused by demons lurking in the darkness. However, humans have illuminated the night's darkness with neon lights, turning their world into one that never sleeps; thus, demons now lurk in the "darkness of the human heart." Unfulfilled hearts, suppressed hearts, despair... such darkness of the heart is where they lurk. Enma is the Demon Prince of the Underworld, a demon "Born of Fire." His mission is to retrieve or destroy demons that have escaped from the Underworld to the human world. Along with his partner, Princess Yukihime, "Born of Ice," and the monster Kapaeru, Enma establishes "Enma's Detective Agency." Tonight, as on any other night, they will roam the sleepless city. Horrific incidents that could not possibly be human acts occur one after another. The stench of evil lingers at the scene... Enma's fire tears through the darkness!
