Happiness will be granted to those who obtain the wings of a nymph.

Due to this legend, many nymph hunters prey upon them for their wings. The Nymph Hogodantai is an organization that protects nymphs from hunters. These nymphs are mysterious people that live in hidden villages, can hide their wings at all, and have the power of illusion.

Along the way, Ren meets Ciel, a member of the Nymph Hogodantai. In spite of their conflicts of interest, Ciel tags along with Ren as he follows traces of Iia. Can Ren keep his identity secret? What are Ciel's motives?
