The city's academies operate independently within their own districts, overseen by the General Student Council, which serves as the governing body for all academies. However, the council's effectiveness has been compromised following the mysterious vanishing of its president. With numerous issues plaguing Kivotos in the president's absence, disaster looms.
To address these challenges, the General Student Council turns to the Federal Investigation Club, also known as Schale, the city's newest and most recently approved club. Tasked with restoring order, Schale relies on the guidance of a Sensei to navigate the incidents unfolding across Kivotos.
In this Academy City, students are mandated to carry personal weapons and smartphones, offering a glimpse into the realm of military action, love, and friendship that awaits.
