Yoh Asakura is a shaman–one of the gifted few who, thanks to training or natural talent, can channel spirits that most people can’t even see. With the help of his fiancée, Anna, Yoh is in training for the ultimate shaman sports event: the “Shaman Fight in Tokyo,” the once-every-500-years tournament to see who can shape humanity’s future and become the Shaman King. But unfortunately for Yoh, every shaman in the world is competing for the same prize…
Funbari no Uta is set seven years later (2007) after the Shaman Tournament, and revolves around Hana Asakura, the son of Yoh and Anna. Hana and Ryunosuke Umemiya are searching for the members of Team Ren and Lyserg for the grand opening of Funbari no Onsen, which is run by Tamao in the story. The story ends with a montage of panels showing all the aforementioned characters preparing to travel to Funbari no Onsen, ending with a spread of Anna and Yoh.
Mappa-Douji – Is a manga created by Japanese mangaka Hiroyuki Takei. It is one chapter long and is the tale of Hao Asakura, a Shaman King character, as a child 1000 years ago. In this original incarnation, his name is Asaha Douji. He was named after his mother, Asano Ha, who was killed by humans for being a yokai who could see and speak with demons. After his mother’s death, Asaha is left with no home and no family. He meets and befriends a demon named Ohachiyo who renames him Mappa Douji (Demon Child), to avoid confusion between his and his mother’s similar names, as the kanji could be pronounced both ways. Ohachiyo teaches Mappa Douji many things, and towards the end of the story he gives Mappa Douji the demonic power of reading minds, the beginning of Hao’s powerfully and dangerously gifted mind.
It is not told in this story, but in the main Shaman King manga, Hao later becomes an onmyōji, which is a hint that Hao’s fictional life may be based on the Japanese legend of Abe no Seimei, a famous onmyōji whose mother was also rumoured to be a yokai.
