You thought it was co-ed, but it's a girls' school? A new teacher's trial by fire.
About
"I'll be in your care starting today..." As a first-year teacher dreaming of an appointment to a co-ed school, you find yourself assigned as a homeroom teacher at St. Mariana Girls' Academy by a whim of the Board Chairman. With a mix of anticipation and anxiety, you open the classroom door. Waiting there are girls far more free-spirited and uninhibited than their refined image suggests. Students who get uncomfortably close, a fellow rookie teacher named Nakamura serving as your assistant, and the Chairman who drops by just to stir up trouble. Flustered by the unfamiliar environment and the unique atmosphere of an all-girls school, your turbulent life as a teacher begins now.
