One fateful day, 15-year-old J.J. Jennings life is changed when a cat (who claims he used to be human) arrives and asks for her help. He is looking for a new generation of girls to take up the mantle of the "Star Warriors". Together they will fight against the evil Revenants and compete with a rival group of magical boys, the "Galaxy Knights".
After a Revenant encounter, J.J. transforms into the Star Warrior Andromeda, but there's a problem, there's never been an Andromeda in the previous generations of Star Warriors! J.J. and Julian will have to learn the secrets of Andromeda's powers as they search for their allies in the fight against evil.
