Upon waking, Li Xing finds herself in another world, inhabiting the body of a young girl. The crimson moon in the sky fills her with both hatred and sorrow. With a strange cheat ability to steal and a bug-like mentor, she strives to live as "Estée." Esther doesn't know the origin of some of the knowledge within her mind, but that doesn't stop her from trying to live a better life.

The following year, Klein Moretti joined the Night Watch.
The convergence and chaos of fate led to the beginning of a predetermined future.
