Kačó ódži: Hard Rock Save the Space

Life can crush your dreams. Oji is a middle-management drone stuck in the drudgery of a corporate lifestyle to support his wife and his kid. His only grip on his sanity come from the 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 and mysterious woman informs him that only his special sound can save the universe from an evil alien invasion!
