My Fiancée Who Calls Herself a Villainess Amuses Me to No End

Adventurous otaku, we now have an isekai series where the isekai protagonist is not the point of view character. Prince Cecil’s lovely fiancée turns heads with her outlandish tales of other worlds and “otome games.” She claims she comes from a place called “Japan” and that her new life comes from a game she once played. Cecil doesn’t take it seriously; he thinks she’s funny and unpredictable. His attitude changes when her tales of events that have yet to occur happen exactly as she says. We’ll see how he deals with her warnings when An Observation Log of My Fiancée Who Calls Herself a Villainess (Jisho Akuyaku Reijo na Konyakusha no Kansatsu Kiroku) premieres on April 6th, 2026.

My Fiancée Who Calls Herself a Villainess Keeps Me Entertained

Prince Cecil always excelled in everything she accomplished. His parents and servants saw him as the perfect prince even as a child. That perfection bored him to no end. He found an unexpected source of entertainment in his fiancée Bertia. She claims to be a “reincarnator” from Japan. Bertia lived a hollow life and only found solace in an otome game. Cecil thought she was mad, but her claims of another world and her desire to be a righteous evil flower were fantastical and entertaining.

Cecil even found Bertia’s warning of an epidemic a bit amusing. He took her seriously enough to grow and stockpile rare healing herbs and formulate a cure for the disease she warned of. Cecil was surprised when patients began presenting with symptoms that matched her description. He managed to avert a catastrophe thanks to her. The prince began to take his fiancée’s claims more seriously, even if they were outlandish and amusing. Except the conspirators who tried to use her (Cecil and Bertia’s father) want to hang them all.
