Synopsis

Just before playing the sequel to an otome game, "Sacred Knight of the Stars 2," Sayaka, a high school girl, was summoned to the game world. According to the butler Jill who summoned her, it seems that she is in the position of the villainess lady who must steal the power of the stars from the Sacred Knights. Attempting to firmly reject him, her ultimate bias of this world, Leo, appeared before her eyes. "My bias and I are in the same dimension-!!" Sayaka delightfully exclaimed, however, Leo has been completely ruined...? She will not accept this scenario! For the sake of the rectification of her most beloved, Sayaka shall rise as a villainess lady! (Source: Kadokawa, translated)
