Heiwa na Gakkou

A group of students and staff at a school experience a series of strange and unsettling events. The initial chapters describe a lack of immediate incidents, followed by a focus on a parent perceived as a hero. The final chapter, published in Comic Zero-Sum in July 2016, is titled "Peaceful School," suggesting a thematic shift or resolution. The story spans several issues of Zero-Sum Ward from 2014 to 2015, with a total of eight chapters plus an untitled extra.
