Legend of Black Heaven

Oji Tanaka's life as a salary man in Tokyo is far from ordinary. Fifteen years ago, he was the lead singer of a short-lived heavy metal band called Black Heaven, known as "Gabriel". When Layla, a mysterious woman, invites him to play his Gibson Flying V, he unwittingly reconnects with his musical past and becomes entangled in an intergalactic conflict where his music holds the key to a powerful weapon.
