As a shaman, Anna possesses tremendous spiritual ability and mastery of shamanic techniques; her impressive strength allowed her to seal in Hao Asakura's shikigami guardians - Zenki and Kouki - and take control of them as her spirit allies. She shows little fear of Hao, whom she detests, and does not hesitate to successfully slap him. In response, Hao expresses interest in her, possibly because she resembles Asano-Ha, the mother of his original incarnation 1000 years ago, and because of the extent of her power.
