Summer, 1999

Guest, Kukuchi, Takeya, and Ohama are four friends spending their summer vacation in a small town. Going to the beach, hanging out in town, talking about nothing. It was a fun summer vacation, just like any other.

However, there is one strange thing about this town.

On the calendar, there is a date that shouldn't exist: "July 32, 1999."

And when July 32nd arrives, one of the four is murdered by someone.

At that exact moment, time rewinds to July 21st.

The victim returns as if nothing happened, and the townspeople have no memory of the previous events. Yet, with every repetition, Guest alone begins to regain memories of the past summers.

At first, you thought it was a coincidence. But no matter how many times it repeats, someone is always killed.

To end this strange summer, Guest tries to find the culprit before July 32nd arrives. However, with each loop, the culprit's actions, the relationships between the four, and the events in town change slightly.

The summer vacation that was supposed to be fun gradually transforms into a world like a "puppet show" as it repeats over and over.

Find the culprit by July 32nd, fulfill the objective, and create a summer where no one dies.

That was the only way left for the four of them.
