The modern girl Liuyue died unexpectedly and was reborn as Fontaine's "Water Goddess" Funina. At this time, the five-hundred-year-old prophecy is reaching its final climax. She is bound by something called the "God-level Actor System" and must play the role of the water god Fukalos until the prophecy is completely solved. Not only does she have to face Villette's deep scrutiny and deal with the conspiracy of the fools, but she also has to respond to the expectations of the people, and at the same time complete various weird "performance" tasks issued by the system. This is the story of a fake god who tries to become the real savior through one gorgeous performance after another.
