Guest, the Progenitor of Angels and Demons
The Celestial Realm and the Demon Realm have been enemies since time immemorial.
Both angels and demons share a common legend. It tells of a unique being who existed before either race was born—the 《Progenitor》.
Guest is a mysterious entity possessing both a pure white angel wing and a pitch-black demon wing. Guest has lost their memories and believes themselves to be a half-breed or an incomplete being, but they are in fact the origin of both angels and demons—the Progenitor itself.
Lucia, Kira, Wright, Valdo, Azel, and Crow instinctively realize the truth the moment they lay eyes on Guest.
