Himehibi: Another Princess Days ~White or Black~

Kisakino Emi is an orphan whose parents died in a car accident when she was in middle school. She’s been living at an orphanage but attending a local high school, living an average life. One day she gets an invitation to a fancy ass all boys school owned by the rich Sumeragi corporation. Their goal is to have a girl, a “Princess” so to speak be in the school for a year to help them test waters to make the school reopen as a mixed gender school. Unfortunately there’s a catch – she cannot tell her friends, or anyone, as it’s a top secret project, so they basically cut off all her communication and force her to live as the Rapunzel of Sumeragi Gakuen.
