I’m a villainess!” Bertia declares this as soon as she opens her mouth, revealing that she has memories of her past life and is the
“villainess” of something called a “girls’ game.” Her goal is to become a respectable villainous lady who can be proud of herself in public, so that her “conqueror target,” Cecil, will break off their engagement. To achieve this, Bertia plots various evil deeds day and night, but her clumsy behavior and kind personality mean that her plans always go awry. However, it seems that there is a reason why she absolutely must be “punished” as a villainous lady… Is her fiancée wandering around in his quest to become a first-class flower of evil? 【About the Fantasy Novel Label “Regina Books”】 This is a new type of fantasy label featuring female protagonists.
