Misha is a unique character in the world of Ar Tonelico. She belongs to the pure-blooded Reyvateil race, which gives her access to more powerful spells than other members of her kind. Her primary purpose in life is to sing the Chronicle Key song, which helps suppress Mir, an evil force that threatens the balance of the world. Misha has been friends with Lyner since childhood and is known for being a good cook. Despite appearing composed and dispassionate at times, she can also be childish and bold in her actions. She suffers from acrophobia and is somewhat clumsy, but these traits do not detract from her overall character. In the game, Misha specializes in thunder and ice magic, making her a formidable opponent for those who cross her path.
