Ten years ago, Fujiwara noticed he had the power to see multicolored auras surrounding people's bodies. Ever since then, he has been having a weird dream about a war with cats. One day, he meets a mysterious girl who, after being picked on by crows and falling from a tree, goes to search for her lost hat. Later that day, Fujiwara finds himself in a daydream, being attacked by the same cats he fights at night.
