Rina Kawaguchi will play Stella, another giant girl, in the TV anime of Nikumura Q's Giant Ojō-sama (Giant Young Lady), the production announced on Friday (Nov. 13). The casting was revealed on the official X/Twitter account with a character trailer, ahead of the series' January 2027 premiere.

The staff presented two new cast members alongside two short trailers. Kawaguchi's casting follows that of Risa Imayanagi, announced the week before, who plays Madoka Ito. Madoka is a member of the "Secret Service" and also becomes a giant girl.

Returning and previously announced cast

Yū Serizawa stars as the title character, Oriko Fujido, and Junya Enoki plays Dr. Sebastian. With Kawaguchi and Imayanagi, the announced cast now covers the lead, two giant-girl characters and the doctor.

The comedy manga centers on Oriko, the daughter of the Fujidou conglomerate, a world leader in vending machine development and distribution. Her father gave her an entire city when she was four years old. Over the past ten years she has devoted herself to the city's growth and prosperity.

Staff

Hiroshi Ikehata, whose earlier work includes WITCH WATCH, directs the anime at Tatsunoko Production. Katsuya Oshima is assistant director.

Hajime Mitsuda is both character designer and chief animation director. Yū Satō handles series composition and writes the scripts. The music is by Yūsuke Shirato, Kijibato and Aira, as Anime News Network listed in its report on the casting.

The series premieres in January 2027.
