Kivotos is a federal megalopolis made up of thousands of schools, governed by the General Student Council (GSC). Ironically, even though it is an academy city, Kivotos is full of gun violence, and every student carries firearms as a normal part of daily life. As if the troubles in Kivotos were not enough, the GSC president has vanished without a trace. Luckily, before she disappeared, the GSC president asked Sensei, a teacher who is probably the only one in Kivotos, to help students when they need it. Sensei's first task is to assist Abydos High School, a school that was once prestigious but now has only five students left. These remaining students are doing all they can to pay off their school's crushing debt of nearly one billion yen.
