Blue Archive the Animation - S01

Kivotos is a sprawling city made up of thousands of schools, governed by the General Student Council (GSC). Despite its academic focus, the city is oddly plagued by gun violence, and students carry firearms as casually as textbooks. To make matters worse, the GSC president has vanished without a trace. Before disappearing, she appointed Sensei-possibly the only actual teacher in Kivotos-to guide and protect the students. Sensei's first task is to help Abydos High School, a formerly prestigious institution now reduced to just five students. Struggling under a crushing debt of nearly a billion yen, these few remaining students are fighting to save their school from ruin.
