I adopted a child demon from the Gap, and I'm a special agent for the Bureau of Supernatural Ab

On that day, in that deserted alley late at night, Li Cheng encountered the severely injured and collapsed little demon girl, and inexplicably took her in, thus beginning their cohabitation as a human and a demon.
A near-future magical city, a civilization shrouded in anomalies. Magicians, superpowered individuals, martial artists, ancient masters of mysticism, and those who transcend the boundaries of the realm. Chaotic conspiracies, shadows hidden beneath the light, rise and fall among humanity.
And in this world, he, the maintainer of order, and she, an outsider, begin to write their own story.
