An Observation Log of My Fiancée Who Calls Herself a Villainess is an isekai fantasy ONA anime with a lighthearted slice-of-life comedy tone, produced by Ashi Productions under the direction of Junichi Yamamoto, with series composition by Akiko Inoue. Based on the light novel by Shiki, the series centers on Bertia Ibil Noches and Cecil Glo Alphasta, offering a charming blend of shoujo sensibility, everyday warmth, and fantastical worldbuilding for fans of comedic isekai stories.

An Observation Log of My Fiancée Who Calls Herself a Villainess follows the delightfully unusual story of Bertia Ibil Noches, a young noblewoman who harbors a remarkable secret: she is a reincarnated soul with memories of her past life. What makes her situation truly extraordinary is that the world she has woken up in is none other than the otome game she once adored—except she didn't get to be the heroine. Instead, Bertia finds herself cast as the villainess, engaged to the game's flawless Crown Prince, Cecil Glo Alphasta. Armed with full knowledge of the story's plot, she is utterly convinced that her destiny is to play the scheming antagonist and meet a fated downfall. Committed to fulfilling her role, she throws herself wholeheartedly into acting wicked and devious. Yet somehow, every sinister plan she hatches seems to have a mind of its own, producing results she never quite intended.
