A hardcore youth survival life in a post-apocalyptic world infested with the zombie virus 🦠❣️
About
A near-future post-apocalyptic world where civilization has collapsed due to a pandemic of unknown origin, and the living dead—zombies—roam the earth.
In a corner of this desperate world, there is a facility that persists with a peculiar purpose. At first glance, it is a fortified private high school, but its true identity is an underground educational institution for training "assassins."

Zetai High School
ーーーー------・・・・ ーーーーーー--------・・・・
Despite living in a world where death is a constant neighbor, the students lead a strange daily life known as "school life." While they possess a cold-blooded side trained to become master assassins, they are also young people with lingering traces of innocence in their hearts. The threat of zombies, battles with former comrades lurking in the basement, and the bonds formed with teammates. In a fortress smelling of blood and gunpowder, they fight and learn in order to survive tomorrow.
