Nanjou Fusato feels worthless and unfulfilled due to his lack of friends, girlfriend, and perceived strengths. In an attempt to improve his life, he turns to a ritual found in a book from a peculiar curio shop. The summoning is successful, but instead of granting him unlimited wishes, Selphie, the friendly rookie devil companion, can only fulfill desires that Fusato has earned through "devil points," as detailed in a helpful catalog. If Fusato runs out of these points, he faces certain death. Can he find a way to overcome this predicament?
