Nagumo Tsubaki♀

A newly-appointed high school teacher. Because she’s new and a woman, she takes on a firm attitude at work to make sure her students and coworkers don’t take her lightly. However, in pursuit of her identity as the ideal teacher, she ends up driving herself into a corner. Putting on a front and hiding her true self have left her mentally and physically exhausted and in need of help at Relaxation Yubihara.
