Gramma, known as Obaa in the Japanese rendition, is the grandmother of Yuna Kamihara, a protagonist in the *Stitch!* anime. She shares a home with Yuna on Izayoi Island, a fictional isle within Okinawa’s Ryukyu archipelago. A sage elder, she anchors Yuna’s world after the loss of Yuna’s mother in a typhoon. Her late husband, Yuna’s grandfather, once instructed Yuna in karate and bestowed a protective moonsand charm upon her before departing their household. Steeped in local lore, Gramma upholds beliefs in yōkai inhabiting Izayoi’s Chitama Forest, guiding Yuna and Stitch through tales of the Chitama Spiritual Stone—a mystical relic tied to wish-granting for those performing 43 virtuous acts, pivotal to Stitch’s journey. She navigates island tensions, such as reconciling the feuding yōkai Kijimunaa and Tachicchu over a pilfered home tree, drawing on her folklore expertise. Engaged in tradition, she marks her birthday with a wind chime crafted by Yuna and Stitch, a celebration briefly upended by Experiment 624 (Angel). Her home extends warmth to Stitch, Jumba, and Pleakley upon their arrival, fostering Yuna’s resilience amid challenges, including rivalries with Penny and Sasha. Her identity remains intertwined with caregiving and cultural stewardship, her history before Yuna’s upbringing and external events beyond the series’ scope left uncharted.
