Blue Archive the Animation - Season 0

The city's academies are divided into their own districts and are considered mostly independent. The General Student Council acts as a governing board to manage the academies as a whole. However, the group's ability to govern has come to a halt since the mysterious disappearance of the General Student Council president. Countless issues have begun to surface throughout Kivotos in the absence of the president's leadership. To avoid disaster, the General Student Council requests assistance from the Federal Investigation Club, otherwise known as Schale. In fact, Schale is the city's newest club and the last to be approved before the president's disappearance. To accomplish its task, Schale relies on the guidance of a Sensei who can help them resolve the incidents around Kivotos.
