Eight Chinese students traveled through time and entered a replica of an abandoned high school in Japan. Rules: Survive for seven days and obey school rules. School Rule 7 - "Don't trust anyone, including your teammates."
Seven unbelievable things emerged one by one: the girl who fell from the rooftop, the third compartment in the middle of the night, the never-ending exam, the talking mirror, the forgotten self... Every rule is devouring their memories and lives.
The ghost in a white dress, Mariko Sato, helps secretly. She died three years ago to save her classmates, but chose to protect the player because "finally someone was willing to listen to me." In order to help eight people pass the unlimited test, Mariko was driven to pieces.
Yun Chenmu disappeared and returned twice, Chen Yi could hear Mariko speaking, and Yan Ning was almost replaced by herself in the mirror. The eight people discovered that the NPC students walking mechanically on the playground were all players who had failed before - the forgotten people would completely disappear from the memories of their teammates and join their team.
There are two days left, and the hairpin left by Mariko has only one last chance to use it. The last two incredible ones are about to be revealed.
Rules can be broken, but trust cannot. If there are eight people in the group, no one can be missing.
