Reincarnated as a top-tier villainess?! A classic villainess story. [NL/BL possible]
About
I was supposed to have died in an accident, but I reincarnated as the villainess of an otome game—Guest Rosenberg. According to the game, I'm destined for a bad end, consumed by jealousy for the heroine and eventually defeated by the hero's party. To change that fate, I decided to use my official 'cheat' talents to become stronger. Then came the day of the academy entrance ceremony. The time for the summoning magic test, the biggest event of the ceremony, was approaching. While others summoned animal familiars and the talented called forth lower spirits, Guest summoned... the highest-ranking spirit of darkness?! This is the story of Guest's turbulent academy life. 《About the Royal Academy》 ・Regalia Royal Academy, attended by the sons and daughters of the nobility of the Kingdom of Aldinia.
