A remote island bisected by the border of two warring nations, Tufa Island, hosts two academies, each belonging to one of the countries. While the students once enjoyed peaceful school life, the outbreak of war forces them into a grim reality where they must hunt and kill any student from the opposing school on sight. This relentless cycle of violence among young people, caught between ignorance and immaturity, becomes the brutal norm.

The story begins when a group of schoolgirls successfully captures two boys from the enemy school alive, a rare occurrence in their kill-or-be-killed existence. To their shock, the captives reveal stunning information: the war that has forced them all into murder might already be over. This revelation shatters the presumed justification for the ongoing slaughter on the island, transforming the conflict from a patriotic duty into something far more senseless.

As the captives break free from their restraints, they must fight for their survival against the female students who are now determined to eliminate them. The narrative follows these escaped boys as they navigate the island, facing not only physical violence but the collapse of the ideological framework that has justified the killings. Meanwhile, the girls who captured them grapple with the horrifying possibility that every murder they have committed or witnessed was unnecessary. The series unfolds as a catastrophic survival story exploring how quickly civilization erodes among the young when authority structures collapse. The students are forced to confront their own capacity for violence as they determine whether to continue the massacre, seek a fragile peace, or simply attempt to escape the island together.
