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.
Sadamitsu is a troublemaking high schooler who gets dragged into an impossible situation when twenty million alien criminals escape their intergalactic prison and set their sights on Earth. Armed with nothing but attitude and a strange mechanical helmet that transforms him into a cyborg warrior, he becomes the planet's unlikely last defense against an invasion of cosmic criminals intent on conquest and chaos. The catch: he's not fighting alone, though his allies are just as unconventional as he is. Mysterious mechanical creatures assist him in battle, each with their own powers and quirks. Between explosive combat sequences and destructive alien encounters, Sadamitsu struggles to balance his new role as humanity's protector with his tangled relationship with Madoka, a capable woman who challenges him at every turn. Part superhero origin story, part buddy comedy, this series blends frenetic action with genuine character friction. It's irreverent and fast-paced, refusing to take itself too seriously while the stakes keep climbing higher. The chemistry between Sadamitsu and those around him grounds the absurdity, making his transformation from troublemaker to hero feel earned rather than convenient.
