シャイニー・シスターズ ～女装主人公アイドルプロジェクト～

The cross-dressing protagonists met each other at an informal social gathering attended by the ojou-sama schools. While not knowing that they are all guys, they felt a strange affinity with each other. This development was amusing to Yuuki’s master Ran, so she plotted to make them into an idol group and have them perform at an upcoming event in town. After some initial confusion about the sudden idea, they all ended up agreeing due to varying reasons. Will they be able to become idols while keeping their true gender a secret!? [From Omochikaeri]
