A kid inherits a space company and immediately gets conscripted into defending Earth because his dad's greatest invention happens to be a combat robot. The show treats this collision between corporate responsibility and giant robot warfare like a joke, because it is one. Takeo stumbling through alien invasions while trying to run a business that was never designed for this is the entire premise, and it never pretends to be anything more serious than that.
Young entrepreneur Takeo Watta suddenly finds himself running his late father's aerospace company, complete with an unconventional asset: Trider G7, a transformable robot designed for space exploration. When the sinister Lord Zakuron and his cosmic forces begin threatening Earth, Takeo realizes his company's greatest invention needs to become humanity's greatest weapon. What follows is a chaotic blend of corporate responsibility, comedy, and giant robot battles. Takeo juggles the absurdity of transforming a space-faring machine into a combat unit while dealing with Zakuron's relentless attacks. The humor emerges from the collision between peaceful engineering and desperate warfare, with Takeo constantly improvising solutions to threats he never expected to face. The show thrives on its goofy charm and earnest action sequences. Characters react with genuine panic and ridiculous confidence in equal measure. Beneath the comedic chaos lies real stakes: Takeo must evolve from an unprepared heir into a capable leader while his robot adapts to a role it was never built for. It's mecha anime that doesn't take itself too seriously but commits fully to its ridiculous premise.
