Photon Earth is a powerful pre-teen boy who lives with his adopted sister, the young (and also powerful) teenaged Aun. After Aun runs off to attempt to be with her rock-idol, Photon goes off to bring her home. In the process, he stumbles across the wreckage of a spacecraft. Inside in stasis is the 20-something Keyne, who's come to this 'Sandy Planet' (aka: Earth) to find the legacy of her grandfather and the secrets of Aho, a technology that endows the user with incredible power.
