Ten years ago, the mad psychic Levi Rah opened a gateway to hell in the center of Tokyo, slaying the great hero Genichiro and transforming the ward of Shinjuku into a city of demons. When Rah's minions kidnap the World President, the tyrant fails to anticipate two things: the president's headstrong daughter, Sayaka, and Sayaka's reluctant protector, Kyoya, Genichiro's son, who is destined to inherit his father's legendary abilities... if he can survive long enough to use them!
