Past life, past life, I am your present life. If you want to continue our connection, please draw a circle on the paper. In the stone room of a deserted island, seven men and three women are playing a game. It is said that all pens before were people who died unjustly, so you can't ask their names. When the pen tip moves on the white paper, the first scream echoes through the island under the moonlight... Not all games can be played! Seven rules, seven iron laws, no one can escape. Every night there will be a vote to decide who will enter the basement's unpredictable iron door. There can only be one survivor among all the people! Yes, this is the indication of the pen spirit, but it is just the beginning...
