Four Seminoan Warriors

They were four warriors (five in the anime) who travelled to the Patch Village five hundred years ago in order to participate in the Shaman Fight.

Past
Five hundred years ago a member of the Patch Tribe visited the village in which the Seminoan Warriors inhabited, inviting them to take part in the Shaman Fight that was occuring during this period. The warriors decided to undertake the journey, with the best of intentions, but on their travels to the Patch Village they encountered Hao. At theis point Hao was a member of the Patch Tribe and attempted to recruit the warriors into his faction. When they refused, Hao proceeded to kill all of them using the Spirit of Fire.

The warriors were first seen in the series when the Kanachi Dolls they now inhabit were displayed by Lilirara as she prepared to stop Yoh and his group from continuing any further in the Shaman Fight. Ren is able to block their initial attack, kicking one and then commenting how weak they are. At this moment, the form of one of the Seminoan Warriors emerges out of the doll and appears to cut off Tao Ren's leg. Lilirara then commands her oversouls to cut Ryu in half, pierce Asakura Yoh's heart and cut Horohoro's arm off. However, it is then revealed that Yoh and company are uninjured and Lilirara explains that the attacks were just memories that flooded into them upon contact with the dolls, which is why they felt pain. Lilirara then offers them the chance to experience the past of the Seminoan Warriors, which Yoh and company accept even after knowing the pain they will have to endure to do so. She commands her oversouls to take hold of of Yoh and company, then proceeds to narrate what happened to the warriors during the last Shaman Fight.

Over Soul Kanachi Dolls
O.S. Kanachi Dolls

Description: These are Over Souls made from Kanachi dolls. With Seminoa magic, Lilirara can integrate the ghosts present within the dolls, with their victims and share the ghosts' experiences and pain through threw form of visions, by directly invading their mind. To do so direct contact with the dolls must first occur; the longer they remain in contact with the victim, the more and more precise the visions become. Lilirara refers to this process as High Speed Image Memory Soul ('High Mega Vision Memorial' in the anime).
 * Shaman: Lilirara
 * O.S. Type: Spirit Type
 * Spirit Ally: The Four Seminoan Warriors
 * Media used: Kanachi dolls

Anime/Manga Difference
As Chocolove was present with Yoh's group at this point in the anime, the number of Seminoan Warriors was increased to five, instead of the four present within the manga. This meant all members of the group could be possessed at once and so see the visions together, rather than one being left out.

Trivia

 * The Warriors names are Nitsuba,Yofia,Ian, and Drysa. The one in the anime is named Chelga
