Enma is a character brought to life by the legendary manga creator Go Nagai. Now, this beloved figure appears in a seductive Japanese horror anime aimed at adults. It is a spine-tingling erotic thriller where Enma tackles complex and gruesome incidents caused by demons hiding in the shadows. However, humans have illuminated the night with neon lights, turning their world into one that never sleeps, so demons now dwell in the "darkness of the human heart"—unfulfilled desires, suppressed emotions, despair, and other such inner shadows become their hiding places.
Enma is the Demon Prince of the Underworld, a demon "Born of Fire." His duty is to retrieve or eliminate demons that have escaped from the Underworld into the human realm. Together with his partner, Princess Yukihime, who is "Born of Ice," and the monster Kapaeru, Enma establishes "Enma's Detective Agency." Tonight, as on any other night, they prowl the city that never rests. Horrifying incidents beyond human capability occur one after another. The stench of evil lingers at each scene... Enma's flames tear through the darkness!
