Five years ago Shibuya declared its independence from Japan. Arround the same time an earthquake destroyed most of the buildings. The evil Irusaibu now rules Shibuya, and the people have become obsessed with a game called Pray, in which two or more individuals alone or in groups play music directly into the brain of their opponent. Tasuku saves a young girl, Shōko, from an Itasu monster. She has amnesia and lives with Tasuku. Meanwhile Shōko and her surroundings are monitored, and there is a rumor that when all of Shibuya sings, it will return to Japan through a rainbow. It is soon revealed that Shoko has a great voice for Pray, and many more games follow. (Source: ANN)
