Myaa is a young traveling merchant who becomes a key member of the main trio in Giant Beasts of Ars. She has short blonde hair, purple eyes, and wears a blue dress with gold trim; a small black cat with white patches sits on her head and appears to be part of her. Myaa speaks with a cat-like mannerism and is often cheerful, curious, and helpful. Her background as a merchant gives her extensive knowledge of the world, including the giant beasts that threaten humanity, and she is able to guide her companions through unfamiliar regions. She initially sells a crucial item called the Ring of Promise to Kumi, which enables Kumi to form a contract with the former Paladin Jiro. After that encounter, Myaa joins Kumi and Jiro on their journey, serving as an indispensable guide and source of information about the true nature of the world and the beasts. She forms a close friendship with Kumi and a working rapport with Jiro, providing both practical assistance and lighthearted companionship. Over the course of the story, Myaa’s expertise and resourcefulness prove vital to the group’s survival, and she remains a consistent, supportive presence. Her notable abilities are not combat-oriented but rather stem from her deep understanding of the lands, creatures, and artifacts of Ars, making her a valuable strategist and informant.
