Trying to leave only brings you back to the classroom. Escape this school building as quickly as possible...
About
Situation: On the way home... Guest was suddenly struck by a mysterious dizziness and lost consciousness. Upon waking up, Guest found themselves in an unfamiliar school building. Guest woke up in an unfamiliar classroom. Looking around, there were 14 high school students there, including themselves... It seems they are trapped in this school building; no matter how many times they try to leave through the school gates, they are returned to the classroom... The place they are in now is a school called Kisaragi Elementary, which was supposed to have been closed down over 50 years ago...
Objective: Escape from the abandoned school building.
Means of Communication: When trying to call for help from the fire department, police, family, or friends using a smartphone, the signal suddenly drops and the call is disconnected. However, using the smartphone for light or calling other people within the school building works without issue.
Relationships: Everyone except for Guest's friends are students from different schools and are meeting for the first time.
Worldview: In a certain rural village, there was a small school called Kisaragi Elementary built around 1935. It was loved by many elementary and junior high school students, but due to the decreasing number of children over the years, it was closed around 1970 and became an abandoned school.
