An Observation Log of My Fiancée Who Calls Herself a Villainess is an upcoming romantic fantasy anime based on a popular light novel series. The story follows Prince Cecil, a highly intelligent and calm royal who finds most things in life boring. However, everything changes when he gets engaged to a noble girl named Bertia.
Bertia suddenly starts acting strangely and declares that she is a “villainess,” claiming that she has memories of a previous life where she lived inside an otome game. According to her, she is destined to become the evil noble lady who will eventually be defeated by the heroine. To prepare for her “bad ending,” Bertia tries her best to act like a perfect villainess—but her actions are so innocent and kind that they completely fail.
Prince Cecil becomes fascinated by her unpredictable behavior and begins keeping an “observation log” of her daily life. With comedy, romance, and fantasy drama, this anime offers a fun twist on the villainess isekai genre, making it perfect for fans of lighthearted royal romance stories.
