Shuna

Originally a princess of the Ogre tribe and Benimaru's younger sister. In Volume 2 of the book, she becomes a subordinate of Rimuru, evolves into an Oni through Rimuru's naming, and transforms into a petite beauty with light pink hair, crimson eyes, and two white porcelain horns, standing about 155 cm tall. She evolves into a Demon Oni due to Rimuru's evolution into a Demon Lord species.

She is kind-hearted and reserved, but can be frightening when angry, emitting anger while maintaining a smile. She manages all of Rimuru's secretarial duties and competes with Shion for Rimuru's attention. She always accompanies Rimuru on his foreign travels and is reliable in diplomatic matters due to her grace and manners. She is knowledgeable about herbs and skilled in sewing and cooking, leading the production enterprises such as the magic federation's silk fabrics and culinary research.

Although a non-combatant, she uses a fan as a weapon and has learned practical jujutsu from Hakurou, making her proficient in close combat and efficient in using magical skills. She is granted the secrets of faith and grace by Rimuru, along with Adalman, and learns sacred magic. She possesses the unique skill "Analyzer (Satorumono)," which allows her to analyze objects and magic by sight and use them immediately, and the unique skill "Creator (Umidasumono)," which enables her to create new materials through the transformation, fusion, and separation of substances. In Volume 21, sensing Ramiris's feelings, she decides to save Dino, who is controlled by Feldway, and through this resolve, she acquires the ultimate ability "Guide Maiden (Yaoyorozu)."
