Arisu participates, for the first time, in a game in Borderland. The game is a shrine stage where each player has to pull a fortune, and has to answer a question written on the fortune. If the answer is incorrect a hail of flaming arrows is fired at the players.

Another night falls, another game begins. This time players must participate in a diabolical game of hide-and-seek where teamwork may just spell survival.

The four of Arisu and the others challenge the most brutal psychological type, the "Heart" game... Will the four of them be able to survive?
