Shin was instructed to record a TV program as usual by his sister Hatora, who was a famous artist. When he turned on the screen, he saw a photo of himself dressed as a girl being auctioned for lots of money. Hatora quipped that next time she’ll take a nude photo of him. Sensing danger, he ran away from home... only to realize later that he was still dressed as a girl. He ended up in front of the art gallery and a seemingly rich girl Rena asked why he was there so late at night. Mistaken for a student at the nearby girls-only art school Oukou Gakuen, he was taken inside to observe a bunch of paintings being brought into the gallery. Suddenly, he noticed some thieves and ended up getting taken hostage. After being saved by Rena’s bodyguard Chiharu, he thought he was free to go... but then Rena ushered him into the waiting limousine and took him to her mansion! Rena questioned him how he had known that the paintings were fake and demanded to know his name, upon which he replied Mizuki, which was his surname. With the help of the head maid Akie, he managed to not have his identity fully blown. Then Rena presented him with a school uniform and told him that she had signed him up at Oukou Gakuen after hearing that he didn’t attend school. He will also serve as her maid. Unable to return home, how will Shin..., no, Mizuki fare in this new setting!? [From [url=http://omochikaeri.wordpress.com/2012/03/01/march-2012-eroge-releases/]Hau~ Omochikaeri![/url]]

Tsukasa is a sopranista-in-training, a male who can sing in the same vocal range as a female soprano. He had been studying overseas for the past year and came back to Japan a month early for vacation to surprise his parents. However, they were gone for a trip and were having the house fully renovated while away, so he ended up without a place to stay. After deciding to live alone for the month, he met a girl named Ayaka by chance when she heard him sing at the park. She told him that she had been looking for someone who could sing like him and wanted him to come to her school to sing at the upcoming festival. Even though he was troubled at the sudden request, he wasn’t able to turn her down and ended up at Shinou Academy, a European-style girls’ school. “W-Wait! D-Didn’t I tell you I’m a boy?” “But with your looks and voice…” His complaints fell on deaf ears and after being dressed up in girls’ clothes, he was surprised when he looked in the mirror. Tsukasa agreed to attend Miou Academy for the month as a girl, Izumi, and star as a ‘diva’ at the Shinou Festival one month later.

Naoto worked as the sous-chef at the mansion of the Amagi family, who owns the leading zaibatsu in Japan. One day, he was asked by the madame to assume the chef position at her daughter Sakuya’s school because she thought that she was acting strangely and she wanted him to report back on her. Even though he felt overwhelmed being at the famous Maishiro girls’ school, he was still full of expectation for his new job. Then, his boss Yakumo gave him some shocking news: he will have to dress as a girl and attend school with Sakuya, since it was easier to keep an eye on her that way. Despite his resistance, he was introduced as the new student and cook, Chihiro. If his true gender is found out, then he might lose his job and be reported as a pervert. Will he be able to fulfill his duties as a cook and a student at the school? [From [url=https://omochikaeri.wordpress.com/2016/03/10/march-2016-eroge-releases/]Hau~ Omochikaeri![/url]]

Misaki is an aspiring pianist studying abroad in Germany, with the dream of someday playing the piano that his late father had built. One day, he received a call from his older sister Shiori who was the music teacher at Lilie Girls’ School. She told him that the lone piano that was entrusted to the school would be donated to the museum at the end of the year and asked him if he would take over as the music teacher while she goes on maternity leave. Presented with the opportunity to fulfill his dream, he decided to accept the position and returned to Japan. When he arrived at the school, he discovered that only students at the school have the chance of playing the piano, and only if they are selected to perform on it during the school festival. Thus, he must attend as a student while serving as a teacher. Of course, that means that he must dress as a girl. While he was afraid of the consequences if his secret got out, his desire to take advantage of this final chance made for an easy decision. And so begins his new life as a cross-dressing teacher and student. [From [url=https://omochikaeri.wordpress.com/2017/03/01/march-2017-eroge-releases/]Hau~ Omochikaeri![/url]]

Touya works at the residence of the Shijou family, one of the most prominent zaibatsu in the country, keeping an eye on and being of assistance to the lone daughter Ran. One day, it was decided that the free-spirited Ran will temporarily transfer to the Meigetsu Girls’ School. Since everyone at the school, from its students to the staff, are female, it would be impossible for a boy like Touya to enter on a moment’s notice. “Well, I will be taking care of other duties while you are there then.” “… What are you saying? You’re coming along too” “Eh? But, it’s a girls’ school where boys are forbidden…” “So you’ll be coming with me, as a girl” Not only would he have to cross-dress, but she wanted him to take her place in some situations. Despite his protests, he was ultimately defeated by her tears and unwillingly consented to entering the school as Yuuki. Will he be able to continue helping her there without having his cover blown?
