A new school term begins, as does the season of new encounters. As he surveys his class full of couples, Hashiba Jun'ichi's mind is filled with distress as he asks himself, "Why am I still a virgin?!" Having heard from his friends that the easiest way to fulfill his long-standing desire to graduate from the fellowship of virgins is to kowtow to a gal, Jun'ichi does exactly that and asks his classmate Yukana out. And unbelievably, she actually agrees to date him. What will become of Jun'ichi from now on?

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.
