Five Elemental Warriors

The Five Elemental Warriors (ファイブーエレメンタルーワリーオルスー, "Faibu Erementaru Wari Orusu") are the ones who each receive one of the five Grand Elemental Spirits.

About
The Five Elemental Warriors are five Shamans each chosen by the Gandhara leader Sati Saigan, to be trained in Hell and each receive one of the Five Grand Elemental Spirits.

500 years ago, Hao was reincarnated as one of the tribe members of the Patch tribe and managed to steal the Spirit of Fire from them. He reincarnated in the present together with the spirit, to become the teenage twin of Asakura Yoh. The other four Spirits are currently kept hidden by the Patch Tribe, in the deepest parts of the Great Spirit and guarded by the four kings of Hell, to prevent others from stealing them away.

Sati of the Gandara had plans to obtain the four Spirits and pass them on to Tao Ren, Asakura Yoh, Chocolove McDonnell and Usui Horokeu. It was theorized that once Hao had combined with the Great Spirit, the Spirit of Fire would be detached from him and from that point onwards could be claimed by Lyserg Diethel. She believes that with the help of the Five Great Spirits, the five shamans could defeat Hao even if he has become one with the Great Spirit and obtained the power of the Shaman King.

While Yoh and the others are going through the plants Gandhara is in Hell looking for the remaining spirits. Gandhara manages to collect the Spirit of Wind, Spirit of Thunder and Spirit of Rain while Sati is fighting Enma to get the Spirit of Earth. Hao sent the Spirit of Fire to Yoh and the others while they were in the Plant plateau.
