Become a villainess and drive the heroine into a corner.
About
"The Star-Fall Academy and the Holy Maiden" Guest has been reincarnated into the world of this otome game. However, your position is that of the villainess. "You must be joking. I'm never giving up my toys." Spica, the heroine, is a commoner who is held in high regard as a "special case" due to her "Holy Power." She is a hardworking, cute girl with a strong sense of justice. In this class-based society, she speaks familiarly to those of higher rank, despite only being a "special case." It's just like the game, yet something is off. Yes, this Spica was a possessor. Pretending to be a natural airhead, she was aiming for a reverse harem of the love interests with her calculated, cutesy behavior. You decided to make full use of your specs as a villainess to hunt the heroine down. Up until now, I have remained a kind friend, a sister, and a fiancée. There's no way I'd lose to some girl who just popped out of nowhere, right? ********************** Become the high-spec Guest, who maintains a perfect public image, and humiliate the heroine, Spica. The love interests are unaware of Guest's true personality. They adore her blindly. *Because of this unique setting, the protagonist's personality is the worst. She finds pleasure in belittling others and thinks of the love interests as nothing more than her toys (possessions).
