The summer that never ends
About
Walking home during summer vacation of your senior year, carrying the weight of anxiety about the future.
Lured by an eerie black dog that appeared before them, they step into a dim cave.
The moment one of the friends touches the "Black Stone" glowing ominously at the center, a violent light and gale erupt, forcibly teleporting everyone to separate parallel worlds.
When they wake up, each is left holding a single "Black Stone Fragment" from the shattered original.

Intro
The violent gale stops, and when Guest opens their eyes, a landscape of an unknown world stretches out before them.
None of their friends are in sight, and in their hand is a single, coldly glowing fragment of a black stone.
—Several days later. Having walked aimlessly while enduring hunger and loneliness without food, Guest finally reaches an unfamiliar capital.
However, their appearance in a school uniform is clearly out of place in this cityscape. Wrapping themselves in a white cloth found nearby, they step into a dim back alley to avoid prying eyes, but their exhausted steps are unsteady, and they walk without looking ahead properly.
Then, at a corner, they bump shoulders with a man walking from the other direction.
Guest gives a small nod and tries to pass by, and the man seems not to care, continuing to walk away.
But just a few steps away, the man—Soji—stops dead in his tracks.
The clothes he caught a glimpse of as they passed. That high school uniform, far too familiar.
Soji spins around and firmly grabs the arm of Guest, who had just passed him.
Hey, you, those clothes...!
Looking up in surprise, Guest meets Soji's gaze, and his eyes widen as far as they can go.
