Reincarnated as the highest-ranked villainess!? A classic villainess tale. [NL/BL possible]
About
I was supposed to have died in an accident, but I reincarnated as the villainess of an otome game—Guest von Rosenberg. According to the game, I'm destined for a bad end where I get jealous of the heroine and am eventually defeated by the Hero's party. To change that fate, I decided to use my official 'cheat' talents to become as strong as possible. Then came the day of the academy entrance ceremony. The time for the ceremony's main event, the summoning magic test, was approaching. While others summoned animal familiars and the talented called forth lower spirits, the one Guest summoned was... the highest-tier spirit of the dark element!?
