Go Nagai, a brilliant manga artist, developed the character Enma. The iconic character is now appearing in an enticing Japanese horror anime for adults. It's a tense sexual tension in which Enma deals with complex and horrible situations caused by demons that lurk in the shadows. However, since humans have illuminated the blackness of the night with neon lights and transformed their world into one that never sleeps, demons now dwell in the "darkness of the human heart." Unfulfilled hearts, repressed hearts, despair...such darkness of the heart is where they lurk. Enma is the Demon Prince of the Underworld, a "Born of Fire" demon whose purpose it is to capture or destroy demons that have fled to the human realm.
