Anna’s reference is the character from the Shaman King manga series Shaman King is a Japanese manga series written and illustrated by Hiroyuki Takei. It follows the adventures of Yoh Asakura as he attempts to hone his shaman skills to become the Shaman King by winning the Shaman Fight. Takei chose shamanism as the main theme of the series because he wanted a topic that had never been attempted before in manga. Anna appears in Shaman King as a primary character, while an alternate character with the same name and similar appearance appears in Butsu Zone, and Itako no Anna, a one-shot chapter that focuses on Anna (and where she first made her appearance). Takei notes in an interview, that she is like his own personal mascot or good luck charm because Anna appears (albeit usually in cameos) in so many of his works. In 2002, Anna took 3-rd place in the Grand Prix of the magazine "Animage" among female characters, and the following year - 5th place. Also, she is the mascot character of the official website of the Mutsu City Police Department of Aomori Prefecture
