Shun has a unique power to electrically charge metal materials. A mysterious winged angel-like being named Air picks up on his powers and chooses him to become her partner, thus enhancing Shun’s powers. Shun soon finds out that his classmate Sanari, who he has a crush on, also has a winged angel partner of her own, named Blissful. She explains to Shun that these beings are called Nephylym, and they chose suitable humans to be their "Answerers" to help them purify evil elements (Noirs). Together with Sanari and Tsukasa (Shun’s rival in love and an Answerer as well), they battle alongside their Nephylym against Noirs that possess human beings.
