Edens Zero

Shiki Granbell, a human boy, lives among robots on the deserted theme park planet Granbell in the Sakura Cosmos. His adoptive grandfather, the benevolent "Demon King" robot Ziggy, teaches him to control gravity with a superhuman power called Ether Gear. Ten years after Ziggy's death, the park is visited by spacefaring content creators Rebecca Bluegarden and Happy, whom Shiki befriends when the dying robots force the three off Granbell before expending their vital Ether energy.

Seeking new friends and adventure, the three set out in search of Mother, the fabled goddess of the cosmos. Early in Shiki's voyage, the space pirate Elsie Crimson gifts him with Ziggy's interstellar warship, Edens Zero. Shiki assembles a crew from Ziggy's android companions, the Four Shining Stars, as well as others he befriends: Weisz Steiner, a criminal and technopath from an alternate history created by a time-eating Chronophage; E.M. Pino, Ziggy's memory-impaired EMP android; and Homura Kôgetsu, a young swordswoman and pupil of the deceased Shining Star Valkyrie Yuna. Meanwhile, Rebecca discovers her own Ether Gear ability to reverse time and travel between parallel universes, which she uses to save Shiki after he is killed by the crime lord Drakken Joe.
