Mappa Douji

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.

Characters

*Asaha Douji aka "Mappa Douji" - Asaha is the first incarnation of Shaman King character Hao Asakura. On his first appearance, he is a hateful child because humans had killed his mother for communicating with demons. After this death, Asaha comes to despise his own humanity. Asaha makes it his mission to wipe out the human race for being so ignorant.
*Ohachiyo - Ohachiyo is a demon that had roamed around for 200 years before meeting Asaha Douji, who he gives the nickname "Mappa Douji" to, due to his confusion about Asaha being named after his mother. Ohachiyo teaches Asaha how to write, count, fish better, hina dolls names, birds names and his most important gift, mind reading (Reishi). He tries to persuade Mappa Douji not to feel hatred for humans because they fear and dislike what they don't understand, but at the end of the story we find that Mappa Douji could not accept this and their friendship falls apart. His spirit energy is unintentionally consumed by Hao at the end of the book, cursing Hao with an eternal form of Reishi.
*Asano ha - Asano was Asaha's mother. She was killed by humans (Specifically Densen and his guards) who burnt her house down for being a yokai.
* Densen-Houshi - Is a monk of the Hien period that specializes in exorsicms to get rid of evil spirits. He proves to be a fraud during his confrontation with Hao and is ultimately killed.
