"Please come in, PLAYER 30!"

Zuko and Lucien are two 17-year-old teenagers with very different backgrounds and ways of life. Zuko is an orphan living in an orphanage. At the same time, Lucien is the son of a CEO of a technology company. However, one day when they meet, chaos occurs in the outside world without them knowing. Various terrible monsters appear to spread fear as well as death. At a critical moment, Zuko saw Lucien's body disappear like a sand castle being hit by the waves.

Screams shouted at each other. No hope, no help. And suddenly, both of them woke up in the game they'd been playing, VIATRIX UPHEAVAL. They are also required to enter into contracts if they want to survive.

What kind of contract is that? What will they do next? When humanity begins to be questioned, what has been considered firmness becomes just a fantasy.
