Anime: Demon City Shinjuku Remastered.
The film begins with a battle between former friends, the evil Rebi Ra (also pronounced Levi Ra) versus the short-lived hero Genichirou. Rebi Ra has allowed himself to be possessed in order to gain the incredible powers of evil and plans to summon demons to conquer the world. Defeating Genichirou and destroying Shinjuku, a part of Tokyo, with a devastating earthquake, the area becomes a demon-haunted wilderness. The novel doesn’t have a fight scene between Genichirou and Rebi Ra. It opens with a quiet time in Shinjuku and then in a sudden change the Demon Quake hits only Shinjuku.
Ten years later, the World President, put in place to uphold world peace, is attacked by Rebi Ra with cursed plants indirectly to keep his old master, Aguni Rai, as the protector of the president, occupied. However, Rebi Ra did not know that Genichirou had a son who inherited his powers and more. After an emotional plea from the president’s daughter, Sayaka Rama, the unlikely hero Kyoya Izayoi follows her deep into the heart of the evil city, finding new allies and terrifying enemies along the way. In the novel Aguni Rai asks the Information Bureau Japan Section Chief to look for Kyoya as the only one who could stop Rebi Ra. The Section Chief tests Kyoya with a commando cyborg and then relates to Kyoya that the president is in a life-threatening curse and only has three days to defeat Rebi Ra before the president is killed as the ritual sacrifice to bring the Demon Realm to Earth, which he failed to do years prior, causing the Demon Quake. During the course of explanation Aguni Rai uses a doppelganger to communicate to Kyoya from New York in hopes of convincing him to save the world. Sayaka soon enters and pleads with him to do so as well. Kyoya finally decides to help because of Sayaka’s pleas.
