A sentient motorcycle crash-lands on Earth looking for a hero. What it finds instead is a regular kid, zero qualifications, immediate panic. The comedy doesn't come from trying to make the premise serious, it comes from everyone involved knowing exactly how absurd this is and leaning into it anyway. The motorbike is funnier than the kid. The aliens are jokes with deadlines. This is what happens when a show trusts that watching someone fail upward at saving the world is enough.
A legendary superhero has hung up his cape and settled into lunar retirement, leaving Earth defenseless against the extraterrestrial threats that never stopped coming. His faithful motorcycle, unwilling to let the planet fall into chaos, descends from the moon on a mission: find a worthy successor capable of stepping into those oversized shoes. The search leads the bike to Shougo, an ordinary teenager with zero qualifications for heroic work. He's got no special powers, no combat training, and absolutely no interest in saving the world. Yet the motorcycle is relentless, convinced that buried somewhere beneath his complaints and reluctance lies the hero Earth desperately needs. What follows is a chaotic comedy of mismatched partnerships and increasingly ridiculous alien invasion attempts. Shougo finds himself thrust into the role of Gekkou Kamen, fumbling through superhero work while the motorcycle coaches from the sidelines. Between dodging real danger and navigating the absurdity of his new life, he starts discovering whether heroism is something you're born with or something you become when you stop running from it.
