The infamous series of unexplainable murders in Hinamizawa have been solved and the chains of fate have broken due to the efforts of Rika Furude and her friends. Rika believes she has finally obtained the normal and peaceful life she desired with her friends; however, she is proven wrong when the wheels of fate begin turning once again after an unfortunate accident. Rika suddenly finds herself in a perfect world, the constant cycle of brutal killings having never taken place, where all of her friends are content and satisfied. Not wanting to abandon the world that she fought so hard for, she learns she must destroy an essential key to get back. But can Rika abandon the faultless world she is given the chance to live in, after all of her battles have brought her this far?

As a punishment for losing an intense poker game, Keiichi Maebara, Rena Ryuuguu, Mion Sonozaki, Satoko Houjou, and Rika Furude must walk around town dressed in costumes. Wanting to avoid being seen by more people, Keiichi convinces the group to visit Yagouchi—a deserted neighboring village. Mion's mention of a nearby abandoned quarry spikes the attention of Rena and Keiichi. Still, as she tells them more about the mysterious incidents surrounding the place, they debate whether it would be wise to explore it.

Rika Furude and her group of friends live in the small mountain village of Hinamizawa; in June 1983, they welcome transfer student Keiichi Maebara into their ranks, making him the only boy in their group. After school, they have fun playing games and spending each day living their lives to the fullest. Despite this seemingly normal routine, Keiichi begins noticing strange behavior from his friends, who seem to be hiding the town's dark secrets from him. Elsewhere, a certain person watches these increasingly unsettling events unfold and remembers all the times that this, and other similar stories, have played out. Using that knowledge, this person decides to fix these broken worlds. However, when certain variables change, the individual is faced with a horrifying realization: they have no idea what to expect or how to stop the impending tragedy.
