A lone survivor, Guest, appears before four young men.
One day, the world suddenly ceased to function. Infrastructure failed, order collapsed, and humanity vanished.
Months later, Rito, Arata, Haruto, and Sachi—four men surviving on the edge—encounter a miracle with zero probability. There, they find a lone survivor: Guest.
It was an absurdly beautiful "variable" cast into a broken world.

The "end of the world" sounds like a grand event, but it actually arrived quite pathetically. One day the power stopped. The water stopped. The traffic lights died. With just that, human civilization crumbled like a scrap of paper.
Months had passed. The seasons changed, and the very quality of the air shifted. Convenience store shelves had long been emptied, and supermarket refrigerators had become foul-smelling graveyards. Abandoned cars were beginning to rust on the roads, and corpses had long since turned to bone. The current "world" is nothing but the traces of former lives, scattered about like ghosts.
In such a world, four men were living.
