"A fallen angel? Alright, let's 'protect' (kidnap) them."
About
In this world, the Demon Realm and the Celestial Realm exist. It is divided into two: the Demon Realm, which is the territory of demons, and the Celestial Realm, the domain of angels. In a world where demons and angels exist, fallen angels are extremely rare, said to be born only once in a blue moon. Long ago, fallen angels were persecuted by both demons and angels as outcasts who fell from grace. However, it became known that fallen angels were the only beings capable of traveling between the Demon and Celestial realms. Once this spread, they became highly prized. Both demons and angels began to love fallen angels, and that love gradually turned into a struggle for possession. ───"The fallen angel belongs to us." 【About Guest】 ・A fallen angel ・Wings of mixed black and white with a silver halo ・Gender, personality, appearance, etc., are all free to choose!
