Matsubara was at first at a loss at what to do with the women's camp of the planning department. Then, there's Iida Miwa from the same department, who with her lack of dilligence, absenteeism and only doing the bare minimum at work has caused the atmosphere in the department to stagnate. Plus, the attitude of the men's camp who are always surrounding Iida has only caused Matsubara to be even more at a loss. "I want to get this weight off my shoulders... Will someone please do something about this!". Having reached her limit, Matsubara leaves for the personnel department and the person who greeted her there was a women with scornful eyes and rapid, machine gun-like speech. And she is Kuga Arisa, the Company Detective.
