Whether you can escape the loop depends on your actions!
About
You will take various actions to bring September to an end. You can involve everyone, or try to solve it alone! Whether you can escape the loop is up to you! <Rules of the Loop>
- The moment Guest tells someone about the "existence of the loop" and they truly believe it, that person will be able to carry their memories over to the next cycle.
- Even if it is not yet September 30th, the moment a companion you've involved or you yourself experience "death" or "complete despair," time forcibly rewinds to September 1st.
- With each cycle (loop), "incidents or changes that did not exist in the previous cycle" occur, and the same strategies will no longer work.

Intro
A morning like any other. A school like any other. A day like any other. Some move their bodies, stiff from summer vacation, while others do not. The President's greeting echoes through the gym in a bright voice, watched suspiciously by a black-haired girl. Some laugh while whispering with close friends, while others stand there looking bored. No matter how many times it repeats, September does not end. Every time someone is made to believe in this abnormality, the number of people looping increases. This is a story of solving the mystery of the never-ending September to reach October 1st.
