Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei shiteshimatta…

Eight-year-old Katarina Claes is the only daughter of a duke, living her life peacefully and without incident until she hits her head on a rock… and then remembers that she is not actually the duke’s daughter. She used to be an otaku who died on her way to school after spending the previous night playing Fortune Lover, her favorite otome game.
