About

The setting is a fictional nation with culture and technology similar to the modern era. On a quiet hill in the city stands St. Michael's Academy, a prestigious girls' school boasting over a hundred years of history. Gathering daughters from distinguished families and wealthy households, this traditional academy values not only academics but also etiquette, character, and refinement. The vast grounds are home to majestic school buildings, a library, a chapel, gardens, athletic facilities, and student dormitories, forming a unique world isolated from the hustle and bustle of the outside. As a general rule, the academy is fully residential, and dormitory rooms are private. Students spend a great deal of time together, not just in classes but also during meals, committee activities, and seasonal events. While school rules and hierarchies are strict, interaction between students is relatively free, and after school, the air is thick with talk of romance and rumors. It is not uncommon for close friends to visit each other's rooms. Into this girls' academy, a young man burdened by desperate circumstances has come to transfer—disguised as a girl. The purpose of his infiltration is by no means light, and he cannot abandon it halfway. He has practiced cross-dressing, feminine gestures, and vocalization in advance, and through the recommendation and guarantee of a collaborator, his identity and background as a transfer student have been meticulously prepared. The academy has accepted him based on reliable recommenders and formal documents; those who know his true gender are extremely limited. With his refined features, slender build, and clever use of makeup and clothing, he passes perfectly as a girl on the surface. However, his body has not physically changed. His voice, gestures, physique, and habits acquired as a man remain as elements that could lead to his exposure if he lets his guard down. Particularly troublesome is the close proximity inherent to a boarding school. Changing into uniforms, bathing, physical examinations, and PE classes. Even if there are times he can be alone in his room, he cannot avoid every aspect of communal life. He might be asked about his past in casual conversation or receive sudden visits to his room. Trivial daily events can turn into a crisis of exposure. If discovered, it would lead not only to expulsion and loss of credibility but also the potential failure of the infiltration's objective. Furthermore, the protagonist himself understands the ethical issues of entering the lives of girls under a false identity. On the first day of the transfer, heading to the dormitory with tension in his heart, the protagonist meets Rinka Kisaragi, who lives in the room next door. Rinka is a young lady of excellent grades, proper conduct, and a calm demeanor. Though she has sharp powers of observation, she does not suspect the protagonist from the start. As they interact and she notices small inconsistencies, her interest will gradually grow. Himari Sasaki, in the same grade, is a bright and friendly girl. She talks to the transfer student without hesitation, showing her around the academy and pulling her into her circle of friends. She maintains a close physical distance and sometimes flusters the protagonist with her innocent behavior, but she is surprisingly sensitive to the feelings of those close to her. Meanwhile, Seira Kujo, the head of the disciplinary committee, is a strict girl who values the academy's rules. She has a strong sense of responsibility and cannot overlook injustice or rule violations, but she is fair and helpful. She initially treats the protagonist like any other student, but as unnatural behaviors accumulate, she will heighten her vigilance. Academy life awaits with various events such as periodic exams, cultural festivals, balls, dormitory events, and field trips. As a girl, the protagonist will nurture friendships, support others in their troubles, and sometimes face feelings of love, jealousy, and misunderstandings. What was supposed to be a false relationship for the sake of infiltration begins to change into something irreplaceable as they spend time together. However, the closer they become, the heavier the secret grows. No one knows how the other person will react or how the relationship will change once the secret is known. This is a story where friendship and love, trust and deception intersect within a school life that began with a false identity.
