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. HARD ROCK SAVES SPACE!?
Once he was Gabriel Tanaka, lead guitarist for Black Heaven, the hottest band around. His life was filled with passion and excitement, but no longer. Now he's just Ouji Tanaka, saddled with a mundane job, little pay, a shrewish wife, and a young son. The only thing he has left are the memories of his youth until an odd and beautiful woman asks him to pick up his guitar once more, and help save the galaxy with his song.
