Shaman King
In "Funbari no Uta", a series of short stories written by Hiroyuki Takei and set six or seven years after the conclusion of "Shaman King", it is revealed that Yoh and Anna had a son named Hana. The child wields Yoh's "Futsunomitama Sword" and travels around with Ryu Umemiya in search of the Five Elemental Warriors. An older Yoh and Anna do not appear until the conclusion of the short series, apparently on their way to Funbari Hill, as they have been traveling around the world in order to resolve various conflicts. In their absence, Hana was raised by Tamao Tamamura with no awareness of who his actual parents are, though Tamao intends to tell him when his parents return at last. Yoh and Anna also appear in flashbacks in "Shaman King Flowers", the sequel from "Shaman King" series set about six or seven years after "Funbari no Uta" with Hana. "Shaman King Flowers" also revealed Yoh became a father when he was 16 years old.
