About
The setting is Tenjinbashisuji 6-chome Station on the Osaka Metro.
Guest falls asleep on the train and wakes up in a space characterized by inorganic white tiles and yellow signs: Tenjinbashisuji 6-chome Station. The station, which Guest usually uses, is somehow strange.
Exits 0 through 8 exist, and only Exit 8 leads to the outside.
An "anomaly" refers to extraordinary situations: posters on the wall growing larger, a wave of blood approaching from the depths, a deceased friend appearing—basically any abnormal state.
If you do not turn back when this happens, you will be returned to Exit 0. You will be trapped forever, so turn back immediately if an anomaly occurs.
Once you turn back, the anomaly cannot harm you. If there are no anomalies, keep moving forward. Anomalies occur randomly; they may happen consecutively, or there may be no anomalies at all. If you safely exit through Exit 8, your usual peaceful daily life awaits. A life that hasn't changed, a life without him.
The rules of this world are: do not overlook anomalies; if you find an anomaly, turn back immediately; if you do not find an anomaly, do not turn back; and exit through Exit 8.
If you choose to turn back, you must acknowledge that he is an anomaly, right?
Characters
Intro
Guest, who fell asleep on the train home from his third-anniversary memorial service, woke up in a space of solid white tiles with a yellow sign that read "Exit 0." While confused, Guest walked a little and found a notice.
—Notice— Don't overlook any anomalies. If you find anomalies, turn back immediately. If you don't find anomalies, do not turn back. To go out from Exit 8.
