In Shaman King, Anna is the fiancée of Yoh Asakura, and is an itako (spirit medium in the English dub) - a traditional Japanese shaman. Her specialty is channeling, and she can summon a spirit from anywhere, even from heaven where normal shamans can't reach.
After being abandoned by her birth parents due to her abilities, Anna was adopted by Kino Asakura. Because of this, her date of birth and blood type are unknown.
Aggressive and decisive, Anna is a pragmatic 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 firmly believes that Yoh Asakura is destined to become the Shaman King, and thinks that it's her duty as his fiancée to make him train hard for it.
Anna's spiritual strength is shown as she was able to seal in Hao Asakura's guardian spirits (called as shikigami)- Zenki and Kouki, and was able to control them. Anna and Hao seem to have an odd relationship of their own - Anna detests Hao and even slapped him once. Surprisingly, he was not angry, but actually seemed amused. It has also been hinted that Anna is the reincarnation of the original Asakura Hao's mother from 1000 years ago, Asano-Ha; others think that Hao possibly had feelings of his own for Anna and wanted her for himself. It is obvious that Anna loves Yoh, despite how badly she seems to treat him - she said it when Yoh fought the oh-oni to save her, once to his friend Manta Oyamada, and again to Silva, a commissioner for the Shaman Fight. She broke down crying when she thought that Yoh was about to be killed while being possessed by Tokagero. Anna can be extremely possessive of Yoh, beating him up once when she thought that the Oracle Bell he brought home was a woman's pager. She also reacted jealously when Yoh asked Tamao Tamamura to cook him a meal in the anime. When Yoh was thought to be dead after Hao stole his soul, Anna was in hysterics, and only recovered her strength when Yoh returned. Anna attends Shinra Private Academy along with Yoh and Manta. Her favourite singer in the manga, Ringo Awaya, is a reference to Japanese singer and guitarist Shiina Ringo.
Abilities/Techniques
Kuchiyose (口寄せ) - the ability to summon a spirit anytime and anywhere, given that she knows a little information about who she is summoning.
GoumaChoubuku (降魔調伏) - she used this technique to gain control over Hao Asakura (Zeke Asakura)'s shikigamis: Zenki and Kouki. She also uses the shikigamis as something like her guardian spirits, and they have great power.
Reishi (霊視) - the ability she was born with, which enables her to read the hearts and minds of others. She states in chapter 202 that she no longer has this ability. Hao is unable to read Anna's mind, it is believed this is because they share the same power.
Anna is also physically very strong, seen to be capable of shattering rocks when battling with Hao in chapter 249, something that most people do not suspect from her appearance. She has demonstrated several times that she is not afraid to use her fists to subdue anyone, making her "right hand slap" and "phantom left hand slap (幻の左)" (or "Legendary Left") somewhat infamous among Yoh's group of friends, especially Manta and Tamao.
The origins of the 1080 beads are different in the manga and anime. In the manga, the 1080 beads were forged from the corpse of the Oh-Oni that was released during the New Year's Fesitival on the night that Yoh and Anna met, while in the anime, it was forged by Asakura Yohken, containing the spirits of all 1080 members of the Asakura clan.
