Shooting Star Gakusaver

Years after a massive meteorite crashed onto Earth, a mysterious capsule, referred to as the "black box," is unearthed, leading to the establishment of Project BB, an international initiative dedicated to its study. At the heart of this endeavor is the International Academy, where eight boys, including the determined Manabu Yoshimura, find themselves drawn into an unusual experiment orchestrated by their eccentric teacher, Toukichi Hashiba. Promising academic credit, Hashiba entices them to explore the meteorite's empty chambers, hypothesizing that their strong thoughts can awaken its dormant potential.

As the boys delve into the experiment, they unexpectedly attract the attention of an alien named Wercury, who projects himself from a spaceship hovering above. Claiming to be from the Star of Prokimasi, Wercury demands the meteorite of the Choshin people, threatening to engage in battle if his demands are not met. In a surprising twist, the meteorite responds to the collective thoughts of the boys, transforming into a colossal robot dubbed "Gakusaver." Faced with the formidable Prokimasi robot, Manabu and his friends must unite their wills to harness the true power of Gakusaver and defend Earth from an impending extraterrestrial threat.
