In ancient times, Karura was a princess of Na-Tunku who was later captured and replaced with a Shakukoporu puppet. She managed to escape by killing many soldiers using only her bare hands. Despite being royalty, she chose to live as "Karura" and serve Hakuoro. Alongside her brother Derihourai, they are the last remaining Giriyaginas on Earth. Karura possesses superhuman strength that allows her to wield an incredibly heavy sword effectively in battle, acting much like Hakuoros tank. She is often seen carrying a jug of sake even on the battlefield. It seems that she knew Urutori from long ago, though their shared history remains unknown. During the slaves revolt in Na-Tunku, Karura pledged everlasting devotion and fealty to Hakuoro, the most sacred vow one of her kind could make. After the rebellion succeeded, she renamed Na-Tunku as Karurauatsuurei.
