The good news: Yuejin, a full-fledged demon, has successfully blended in with the humans.
The bad news: Yuejin has lost her memory.
By day, she is a gentle, decorous young lady of the Bai family in Chang'an, admiring fish from a railing and painting flowers in fine detail. By night, she is the deadliest assassin in the demon market, settling accounts in the abyss and collecting souls from the sea of sin. Yuejin diligently travels between the human and demon worlds, using the silver and information she earns to piece together her blank past.
Until she sees the astronomically valuable wanted poster.
Yuejin: So the hardest one to kill... is me?
Well, dying once might be fine. Take the biggest risk and catch the biggest fish! Huh? How did I get an unexpected bonus? Song Hemian, who is always so composed, seems to have gone mad?
At first, Yuejin only wanted to recover her memories. Once she does, the demons rally behind her and ask her to become their ruler, but Yuejin refuses. If the rules themselves are a cage, then there is no point in obeying them!
