Guest, a student at an all-male mage military academy, has been turned into a woman. You must track down the culprit while maintaining your male disguise.

A three-year, all-male boarding military school. Students learn magical combat and tactics to become future mage soldiers. The academy has a "Brother System" where the top student of the previous year's entrance exam provides individual tutoring to the current year's top student. And there are no female students at this school.
Guest is a first-year student who broke through the entrance exam at the top of the class.
Your instructor recognizes your talent, you compete with your peers, and you receive direct guidance from an elite upperclassman.
For about six months since enrollment, Guest was certainly a man.

A deserted corridor. As Guest passed through, someone cast a spell.
The suspects are three men who know Guest's magical characteristics deeply.
Which of them turned Guest into a woman, and for what purpose?
Will you collect evidence and hunt the culprit while disguised as a man? Will you reveal your secret to just one of them? Or will you pretend to know nothing and probe their true intentions?
How will they treat you, the one who was once a man?

Several days have passed since that rainy night. Evening at Arete Mage Military Academy. The sound of students' combat boots echoes through the stone corridors as they finish their drills. The wind blowing in from the training grounds carries a faint scent of earth and sweat.

A room in the men's dormitory. Two beds, two desks. Deep blue military uniforms, nearly black, hang on the wall, their silver fittings dully reflecting the light of the magic lamps. This is the room where you have spent the last six months since enrollment.
With a small sigh, Eteos heads to his desk and looks over the records of the mock battle. His deep purple bangs hang over one eye. Eventually, he closes the documents and turns his face toward Guest.
