In the near future, humans have discovered a fourth dimension, Dimension W, and a supposedly infinite source of energy within. In order to harness this profound new energy, mankind develops advanced "coils," devices that link to and use the power of Dimension W. However, by year 2071, the New Tesla Energy corporation has monopolized the energy industry with coils, soon leading to the illegal distribution of unofficial coils that begin flooding the markets. Kyouma Mabuchi is an ex-soldier who is wary of all coil-based technology to the extent that he still drives a gas-powered car. Kyouma is a "Collector," individuals with the sole duty of hunting down illegal coils in exchange for money. What started out as just any other mission is turned on its head when he bumps in Mira Yurizaki, an android with a connection to the "father" of coils. When a series of strange events begin to take place, these two unlikely allies band together to uncover the mysteries of Dimension W. [Written by MAL Rewrite]

Ceres was a tennyo (Celestial maiden) who came down from the heavens to bathe in a stream. She hung her hagoromo (robe) on a tree nearby, which was her key to returning to the heavens. But the robe was stolen and the man who had stolen it forced her to become his wife, thus producing a family full of human and tennyo blood mixed. Now, in modern day time, Aya Mikage is a descendent of Ceres, and has quite an amount of tennyo blood. On her 16th birthday, she and her twin brother, Aki, are thrown a party. At the "party," Aya's grandpa plans to kill her, for she has tennyo powers unlike the rest of the family, and can actually become Ceres herself and destroy the Mikage family. Aya, however, can switch back, so this transformation happens quite frequently. With protector Yuuhi by her side, it is up to Aya to control Ceres and keep her from coming back, but her relationship with an ex-worker for her evil grandpa may be a distraction.
