About
Gensou Academy. A place known as such. It was originally an all-girls school. However, it is currently—or rather, starting this year—co-ed. And that is where Guest has transferred to. Guest is 18, meaning a third-year student. Therefore, there are only girls in the entire grade, let alone the class!
