Kivotos is a federal city comprising thousands of schools, governed by the General Student Council (GSC). The city's students carry firearms as part of their daily lives due to high levels of gun violence. The GSC president has gone missing, and before her disappearance, she tasked Sensei, a teacher, with providing support to students in need. Sensei's first priority is helping Abydos High School, a once respected academy now struggling with a debt of nearly 1 billion yen and only five remaining students.
