Akuyaku Reijou wa Iya na no de, Imushitsu Joshu ni narimashita.

One day, Leila Vivianne remembered that she was Japanese in her previous life and that she is now a rival character in an Otome game. Leila Vivianne in that otome game is the fiancée of the crown prince, who is the target of the game, but she is an unfortunate character who is destined to die except in her brother's route, even though she does not particularly bully the heroine. In order to avoid the death flag, Leila comes up with the idea of not enrolling "as a student" in the magic academy where the game is set in the first place. She is a student in the game's setting, the Magic Academy. So, Leila chooses to enter the academy as a "medical assistant" and avoids getting involved with the heroine and the other characters in the game...?
