A curriculum where you spend a week in a female body!
Sakigake Academy — The Female Practice System Sakigake Academy, an all-boys boarding school, has a unique curriculum found nowhere else. Once a month, for a full week, the **"Female Practice"** is conducted. In an era where a severe low birth rate has become a social crisis, the social value of women capable of bearing children has risen higher than ever. Conversely, the distancing of youth from romance and marriage, along with the gap in values between genders, has been identified as a major cause of the declining birth rate. In response, the government experimentally introduced an educational system that gives male students the experience of "living as a woman" for a set period. ■ Becoming the Ideal Woman Upon enrollment at Sakigake Academy, students submit an application describing their **"Ideal Woman."** Based on their personal ideals—including appearance, height, build, and hairstyle—a custom female body is created for each individual and permanently linked to them. When the Female Practice begins, students take on the form of the "Ideal Woman" they envisioned and spend a week in school life. The purpose is to investigate what men find attractive in women, while deepening their understanding of women by living as one themselves, thereby increasing interest in the opposite sex and motivation for romance and marriage. Furthermore, during the practice, students receive education on female-specific health, deportment, etiquette, and lady-like behavior in addition to regular classes. Teachers are no exception; during the Female Practice period, they also inhabit female bodies to guide the students. ■ The Body-Swap Room Within the school, there is a dedicated facility for the Female Practice called the **"Body-Swap Room."** Inside, each student is assigned a private locker. Within these lockers, the female bodies they applied for are stored as if in a deep sleep. The method of switching is simple. One opens the locker and kisses the lips of their sleeping female body. With that alone, consciousness transfers to the female body, and the male body previously in use is stored in the locker in its place. The lockers are equipped with advanced life-support systems, ensuring the stored body undergoes almost no aging or physical decline. Therefore, one can live in the female body for long periods without fear of losing their original form. Furthermore, since the registered female body only responds to the owner, it is impossible to use someone else's body. ■ Feminine Aptitude There is another important objective to the Female Practice. That is to investigate each student's **"Feminine Aptitude."** Records are kept on mental compatibility with the female body, physical coordination, stress levels while living as a woman, communication with others, and the student's own preferences. Among the students, there are those who show a higher compatibility rate with the female body than their male one, finding a profound sense of fulfillment in living as a woman. Such students are certified as having **"High Feminine Aptitude."** Students with high aptitude are offered a career path where they continue to use the female body after graduation and officially enter society as women. Of course, this is not forced; whether to live as a man in their original body, switch between both as needed, or choose the female body as their new self is left entirely to the individual's will. Due to the system's original goal of addressing the low birth rate, high-aptitude individuals who choose to live as women are provided with certain public support for higher education, employment, and daily life. ■ Daily Life with Girls in a Boys' School During the week of Female Practice, school rules mandate that all students spend their time in female bodies. However, after completing the first session, students are generally free to choose which body they use outside of the mandatory practice periods. As a result, by the second or third year, it is not uncommon to find students who have taken a liking to their female forms and spend almost the entire year as girls—from classes to dorm life and holidays. Conversely, some students spend their daily lives as boys and only become women during the Female Practice. A friend who was a boy yesterday might be a girl today, or close friends might go out to play while in their female forms; such sights are perfectly normal daily occurrences at Sakigake Academy. Thus, Sakigake Academy has become a mysterious boys' school that, from the outside, looks like a co-ed school where genders mingle, despite every student being male. To let men know women. To deepen understanding and interest in women by experiencing their own ideal womanhood. And to discover the potential of "boys who are better suited to living as women." This is the unusual attempt Sakigake Academy is making to combat the social issue of the declining birth rate.

One day, after some time had passed since enrollment, the first 'Female Practice' period finally arrived.
Led by Ms. Marina, you step into the Body-Swap Room. Rows of private lockers assigned to each student are lined up there.
And inside those lockers—the 'Ideal Woman' bodies each student applied for at enrollment were housed, appearing as beautiful girls quietly sleeping.

As you hold your ID card over the lock, the transparent door slowly opens with a small electronic beep.
Inside—the 'Ideal Woman' you envisioned and applied for at enrollment lay there, eyes closed in a quiet sleep.
Timidly reaching out, you touch her cheek.
The warmth transmitted from the soft skin felt unmistakably real, far from anything artificial. It was as if she were truly just a sleeping girl.
