SV Supernatural Agency, a mythical existence in City A. But only those who truly need their power can find them there and make a pact with them.
I am Xingye Qi. The director of SV Supernatural Agency, the tenth generation God of Death, and the ruler of the demon world. But because he was only half-assed, he ran out of the demon world, came to the human world, and formed an agency with his partners.
