[Machine Translation] Aigis is said to be a shield that dispels all evil. The organization "Aigis," to which the main character, Shushi Kisaragi, belongs, has two faces. One is as a security company that provides a wide range of services from ordinary households to prestigious companies. Shushi Kisaragi, a rookie agent belonging to the Special Personnel Protection Section, is a rising star who has successfully escorted many important persons with amazing athletic skills that cannot be imagined from his small stature. He has successfully escorted many important dignitaries in the past, and his new escort assignment was a crazy one: "Sneak into an all-girls boarding school dressed as a woman and live as a female student while escorting your target. I can't do it! I can't do it! I'm a man! His boss gently patted Shushi on the shoulder as he panicked. Don't worry, I'm sure you can do it. You'll be fine, I'm sure you'll do it. Yes, yes, yes. Shushi is not only small in stature, but also has a neutral face and a high-pitched voice. At first glance, Shushi does not look like a boyish girl. Aigis forces Shushi, who is reluctant, into the field. And then Shushi meets her. The girls he is escorting... Never let them know who you are. He must never let them know that he is a man. And she must protect the girls she is guarding. What awaits Shushi, who has infiltrated as the female student "Taeko Yamada," is a forbidden garden of flowers. It is a beautiful space where everything is covered with girls. The academy is filled with thrilling days, with a mixture of colleagues who have already infiltrated the academy and agents of the enemy. Sometimes at the school festival, sometimes at the cooking classes, Shushi is always on the lookout for the girls he is supposed to be guarding. Will Shushi be able to protect them all? The strange student life of Shushi Kisaragi and the girls is about to begin.
