Giant Ojō-sama anime names Rina Kawaguchi as Stella for January 2027

Giant Ojō-sama (ジャイアントお嬢様; Giant Young Lady) is adding another giant heroine to its upcoming television anime, with Rina Kawaguchi announced as the voice of Stella. The official anime account introduced the character on 13 November and linked readers to the production’s official website. ¹

The announcement identifies Stella as another giant girl, but it does not add a precise broadcast date, broadcaster or streaming service. The series is still scheduled for January 2027, so viewers have a launch month rather than a confirmed day to put in their calendars. The official key visual shows the heroine towering over a city, alongside the series logo and the January 2027 premiere window. ¹²

Kawaguchi joins a cast that already includes Yū Serizawa as Oriko Fujidō, Junya Enoki as Dr. Sebastian, and Risa Imayanagi as Madoka Ito. The production is directed by Hiroshi Ikehata at Tatsunoko Production, with Katsuya Oshima as assistant director, Hajime Mitsuda as character designer and chief animation director, and Yū Satō handling series composition and script. ²

The anime adapts Nikumura Q’s manga, which is serialised on Shogakukan’s Sunday Webry platform. The official site identifies the project as a television anime and provides its cast, character, story and broadcast-information sections, but the January 2027 listing remains intentionally broad for now. That means international availability and streaming platforms are also still unannounced. ²

Our opinion

Adding Stella expands the anime’s central giant-girl premise without pretending that the production has more launch information than it does. The useful detail here is Kawaguchi’s casting and the character introduction; the January 2027 window is worth noting, but fans should wait for the broadcaster and exact date before planning around it.
