Meet Tanaka Oji: lead guitarist of a hard rock band in his youth, now an aging salaryman who has all but given up on his old dreams. Trudging through a boring day-to-day life, he gets a rude awakening when his musical talents are once again called upon — to save the galaxy from invaders, no less... but with age come responsibility; he has a family to look after and can’t just give up his day job, no matter how hot and blonde the reason. The time has come for a decision; will he once again try to live out his dream and rebel, or conform to the demands of society?
