Noshitani Mitsutaka is directing the anime at Magic Bus and Picante Circus studios, and the anime will star Takahashi Rie as Carolina, Furukawa Makoto as Edward, and Shiraishi Haruka as Flora.
The anime is based on the Mujikaku Seijo wa Kyou mo Muishiki ni Chikara o Tare Nagasu: Imadai no Seijo wa Anede wa Naku, Imouto no Watashi Datta Mitai Desu (The Oblivious Saint Can’t Contain Her Power: Forget My Sister! Turns Out I Was the Real Saint All Along!/ 無自覚聖女は今日も無意識に力を垂れ流す 今代の聖女は姉ではなく、妹の私だったみたいです) light novel series by Almond and Ambe Yoshiro.
Author Almond started the story on the Shousetsuka ni Narou website, and Earth Star Entertainment published the first novel, with illustrations by Ambe, in June 2021 and the fourth and final novel in June 2023.
The novel series was adapted into an ongoing manga by Etou Yona in April 2022 on the Comic Earth Star website, titled Mujikaku Seijo wa Kyou mo Muishiki ni Chikara o Tarenagasu: Koushaku-ke no Ochikobore Reijou, Tougisaki de Shiawase o Tsukamitoru! . Earth Star Entertainment published the manga’s first tankoubon volume in October 2022 and the seventh volume in October 2025.
J-Novel Club publishes both the novel series and the manga adaptation in English. All four novels in the series have been released digitally under the name The Oblivious Saint Can’t Contain Her Power: Forget My Sister! Turns Out I Was the Real Saint All Along!. Whereas the manga adaptation can be found under the name The Oblivious Saint Can’t Contain Her Power: Disgraced No Longer, I’m Finding Happiness with the Prince!, and J-Novel Club released the manga’s sixth volume digitally in December 2025.
J-Novel Club describes the novel’s story below:
“Lady Carolina, the overlooked daughter of a powerful duke, has always believed herself to be the black sheep amid her illustrious kin. Her father is the distinguished prime minister; her elder sister, a prodigious mage destined to become their nation’s next Saint. In comparison, Carolina resigns herself to a quiet existence in their shadows until a sudden and unexpected royal decree alters her destiny, thrusting her into a political marriage with the formidable “Bloodthirsty Prince” of the neighbouring Empire of Malcosias. Determined to prove her worth, Carolina takes a bold step into a world fraught with both political and mortal peril. As royal obligations intertwine with hints of true love and the stirrings of her own latent power, Carolina moves ever closer to understanding what it truly means to be exceptional.”
