Yuna (ゆな) is a powerful female thief who helps Jin Sakai with fighting against the Mongol forces on Tsushima. After the Battle of Komoda Beach, Yuna found Jin Sakai and gradually nursed him back to health whilst hiding him for the Mongol army. Once Jin regained his strength she aided him in reclaiming his katana, which she traded for food and medicine, and escaping Komoda Town. During their escape, she asks Jin to aid her in saving her brother Taka who was taken by the Mongols which Jin agrees to do after he saves his uncle, Shimura, from Khotun Khan at Castle Kaneda. Joining Jin in his first attempt to rescue Shimura, she fights alongside him to clear the lower castle but then falls back to prepare the horses and keep the way clear. On the bridge after Jin is defeated by Khotun Khan defeats, Jin finds her in the forest nearby and they part ways so she can search for where Taka is being held.
