Yūna (ユウナ, yuuna ?) is a young tomboyish Japanese girl that is in the new Stitch! Japanese Anime series. She is in 4th grade and lives on a fictional island off the shore of Okinawa called Izayoi. Living on Izayoi, she learned and studies karate, living a rather normal life, but having to deal with minor problems living with her grandmother, Obaa. Her father is out at work a lot as a marine biologist around Okinawa, and her mother died when she was an infant in a typhoon. Her personality is sweet and outgoing, while still tough and feisty all in all. However, one day, she meets a strange creature that has come from the depths of space, Stitch.
She teaches Stitch how to do karate and be "good" while also meeting some of Stitch's family from outer space: Jumba (Stitch's father), Pleakley (Stitch's uncle), Angel (Stitch's girlfriend and cousin), and all his other cousins.
She has a strong sense of justice and an overbearing attitude, which make her a tomboy, and that shows against evildoers like Dr. Hamsterviel, and against rivals like Penny and her gang of bullies. The creators of the anime got Yuna's name from the Japanese name of sea hibiscus out in Okinawa (known in Japanese as Yuna). Yuna's birthday is February 25. It can be assumed that Yuna's favorite animal is a porpoise from a few instances in the series. Yuna isn't good at mathematics, often getting low scores on math tests. Yuna's last name, Kamihara, wasn't unveiled until much later, although previous guesses were Chitama, after the dojo and the forest on Izayoi and Hanako, which was Yuna's previous name and design during development of the anime.
- in the English Dub, When Remmy shows Yuna the memory of her mother humming a tune to her when she was a baby, the tune she is humming is "Baby of Mine" from the Disney movie "Dumbo" the sequences are very similar as it shows the mother cradling the baby in her arms.
