A delinquent kid gets a robot suit and suddenly has to save Earth from millions of alien prisoners while his actual enemy is the girl he can't talk to without combusting. The show treats this premise with complete sincerity: the stakes are absurd, the romance is aggressively awkward, the action is gloriously stupid. Ten episodes of pure early-2000s energy that knows exactly what it is and never apologizes for it.
Tsubaki Sadamitsu is a high school delinquent who leads the Corpse Gang. A chance meeting with an alien robot leaves him stuck with the job of catching intergalactic criminals known as the Exiled Ones, and twenty million of these escaped alien convicts are now threatening Earth. Wearing a mask shaped like a motorcycle helmet, he becomes a semi-robotic masked hero. Other creatures that may be mechanical help him in the fight. Away from battle, he has a rocky relationship with a strong-willed young woman. His work gets harder when the Vulture shows up, a last-ditch measure meant to keep the Exiled Ones in check. The result is a sci-fi action series built around mecha-style transformation and alien battles.
