Hoshi no Otome to Rikka no Shimai

This is a story of the maidens who aim for the "stars". The protagonist, Yamabuki Yuki, is an online streamer who is popular because of his cute looks. Although he is known as an up-and-coming female streamer, he is actually a guy. He gained popularity by streaming as a girl with his good-for-nothing sister, Yamabuki Alice. One day, their mother forced Alice to transfer to a new school, since she had stopped attending her old school. The new school that Alice will be attending is St. Rikka Girls' Academy, a boarding school which has produced many top idols. Men are not allowed to enter even if they are members of the family. In order to be able to take care of Alice, Yuki was asked by his mother to dress up as a girl and take the transfer exam. Yuki thought that this was absurd, but since he was originally a child actor, his mother forcefully entrusted him with it, thinking that he could figure something out on his own. He reluctantly agreed to do it when Alice told him that she will attend the new school if Yuki will attend there as well. Then came the transfer exam. Yuki changed his name to "Usami", took the exam, and successfully passed. Usami dressed up as a girl and attends an all-girls school. What kind of life awaits him(her?) there?
