Hard Rock Saves Space!! Life can crush your dreams. Oji is a middle-management drone whose only grip on sanity in the drudgery of his corporate lifestyle, are the few shreds of hope surrounding his past life as the amazing guitarist of Black Heaven, a heavy metal band that almost made it. In his bleakest moment, the magic of performing is restored to him when a beautiful mysterious woman informs him that only his special sound can save the universe from an evil alien invasion.—Anonymous

Oji Tanaka has a wife, a child and a mundane job as a salary man in Tokyo's modern society. But life wasn't dull for him to begin with; 15 years ago, he was known as "Gabriel", leader of a short-lived heavy metal band called Black Heaven. Oji's life gets a sudden change in direction when he is invited by a mysterious blonde woman named Layla to pick up his Gibson Flying V and once again display his "legendary" guitar skills, not knowing that his music generates power for a massive weapon in an intergalactic war.—ANN
