Long ago, a powerful sentient robot known as GoLion, abused his great powers by attacking and killing creatures known as Deathblack Beastmen, boasting that no one could defeat him. For his arrogance, The Goddess of the Universe punished GoLion by separating him into 5 different lion robots. In the year 1999, a group of 5 young men returned to Earth after a space voyage, only to find it ravaged by nuclear war. After encountering the alien race known as the Galra, the 5 youths end up on the planet Altea and learn that the 5 lion robots that GoLion was split into are in hibernation in various parts of Altea. Somehow, they must reunite the lions and form GoLion, the only hope for the human race.

Cuando la madre de Satsuki (Claire en inglés y español) muere, ella, su padre y su pequeño hermano, se mudan a la ciudad en la cual se crio su madre. Allí Satsuki comienza a estudiar en la misma escuela a la que acudió su madre en el pasado (la escuela nueva, porque su madre fue a la vieja escuela). Lo que Satsuki no sabe es que su familia materna posee una habilidad especial para detener a los fantasmas malignos, habilidad que ella heredó.
