Anna's first appearance in the manga occurs after Yoh narrowly defeats Tao Ren. From there after, she starts her "special training" program to help Yoh become Shaman King; she is unrelentingly brutal with his training to the extent that Yoh refers to the regimen as torture instead. Aggressive and decisive, Anna is a person who, to most, appears cold and harsh. However, she has shown that she genuinely cares for those important to her, especially Yoh, and merely is dedicated to be "the ultimate Shaman Queen" and wife to Yoh, the first real friend that she ever had in her life. She holds a deep gratitude for Yoh for saving her life, thus she believes it is her responsibility as Yoh's wife to train him hard so he can achieve his dream of becoming Shaman King in spite of her claim it is so he can realize her dream of living a comfortable life.
