Returning main cast and core characters

An anime with a unique perspective on the villainess genre
Based on the light novel series written by Shiki and illustrated by Wan Hachipisu, the story follows Crown Prince Cecil, whose dull and predictable life changes when he becomes engaged to Bertia.
She immediately declares herself the villainess of an otome game and claims she must commit evil acts to fulfill her destiny.
However, Bertia’s attempts at villainy often fail spectacularly, leading to unexpected and sometimes beneficial results.
Rather than being alarmed about his crazy new fiancée, Cecil becomes fascinated by her strange behavior and begins documenting her actions. Thus, turning their engagement into both an observational study and an unusual romance.
Unlike many villainess stories told from the reincarnated heroine’s perspective, this series unfolds primarily through Cecil’s point of view, which also offers a fresh take on the genre’s familiar tropes.
