Yurusaba.

For Tsumugi, Momo, and Rin, it begins as the most ordinary of days—time spent with their father, familiar routines, a world that feels exactly as it should. But somewhere between one moment and the next, everything changes. The streets fall silent, the houses stand empty, and the bustling life that once surrounded them has vanished without a trace. As the sisters and their father search for answers, a chilling truth emerges: every other person on Earth has disappeared, leaving the four of them seemingly the only humans left. The cities, neighborhoods, and homes they once shared with millions now belong to them alone—vast, quiet, and unsettling in their emptiness. Stripped of the world they knew, the family must confront an unthinkable question: how do you survive when you are all that remains? With no one to turn to and no explanation for what has happened, Tsumugi, Momo, and Rin must rely on one another—and on their father—as they struggle to endure in a world that has been emptied of everyone but them.
