Summary: A meteorite struck Earth and in the debris a mysterious alien capsule was discovered. Called the "black box," an international organization called "Project BB" was created to research it.
Eight boys, including Manabu Yoshimura, attend International Academy, a school located near Project BB headquarters. They end up getting involved in an experiment to enter the eight empty chambers in the capsule. Then, a big spaceship appears in the sky and an alien calling himself Wercury tells them he is from the Star of Prokimasi and has come to collect the meteorite. If they do not hand it over, he will challenge the earth beings to a battle. Manabu and his friends are confused by the unexpected turn of events but the meteorite responds to the thoughts of the group and suddenly starts to transform itself into a gigantic robot.
