The side story Funbari no Uta, which lasts for five chapters, is set six years after the end of the manga series features Hana Asakura, (it is speculated that Hana is made from the names of his parents, Yoh and Anna. ), and his journey with his uncle Ryu to gather up the 5 elemental warriors: Horo Horo, Tao Ren, Lyserg Diethel, and Chocolove McDaniel. (Yoh being the fifth). While nearly all main characters are present, Manta Oyamada and Faust VIII do not appear. At the very end, two figures can be seen: a woman in a cloak (who is Anna) and a man with long hair who resembles Yoh.
A side story known as Mappa-Douji was also released, which shows Hao's childhood in his original life. It shows his situation after his mother was burned to death by humans and his first friend (not Matamune) and how he gets his mind reading ability and advanced shamanic abilities like oversoul.
Another side titled Relax was released, which showed Hao gathering followers for the tournament years before it started.
The name "Hana" means flower. Hana's name comes from the conjunction of the characters in Yoh (葉, also pronounced as Ha) and Anna's (ナ, Na) names.
