The Office Detective

Matsubara is just one of many ladies in the Planning Division who are feeling rather annoyed. Her fellow coworker, Miwa Iida, is managing to drag the entire office down with every move she makes. And the men surrounding her in the office are only managing to make that worse. "This has to stop... Someone do something!" After finally reaching her limit, Matsubara heads to HR where she meets Asari Kuga, a woman a stern gaze who spits facts like a machine gun... the "Office Detective"!
