BoZ Brothers

The BoZ Brothers (ボズ ブラザ ズ, Bozu Burazazu) are two of Hao's followers and a group of rock monks. Their real names are Sugimoto Ryo (杉本 良,Sugimoto Ryo) and Yoneda Zen (米田 善,Yoneda Zen). They are part of Team "Tsuchi-gumi" (Earth team).

Appearance
When they first appear the BoZ brothers have Komusō over their heads while performing on the streets. When they finally reveal themselves to Asakura Yoh they no longer wear the Komusō and instead were traditional Japanese black robes and overalls. After their defeat by Chocolove McDonell, they wear different sunglasses and wear a simple t-shirt, cargo shorts, as well as acoustic guitars, instead of their former glittering instruments. When seen with the Gandhara, the shirts they are wearing has a picture of a bald man's head from behind on it, showing their allegiance to said group. When they first met Hao, they both wore a simple Kimono and both brothers were presumably bald, with Ryo wearing a bandana. Five years ago, when the duo were known as the BOØWZ, they both had long spiky hair colored black and they wore black Japanese school uniforms.

Personalities
They appear to be rather eccentric, however in the anime this displayed as they are singing about everything when speaking. When they first met Asakura Hao they seemed rather shocked, however they eventually grew loyal to him.

After Peyote Diaz misused them as mediums for his oversouls, however they quit their allegiance to Hao, deciding to once again pursue a musical career. Ryo seemed happy just playing Buddhist music, but Zen dreamed about teaching the Buddhist doctrine all over the world to make all evil spirits disappear.

Abilities
The brothers are capable musicians that have sold several records. Yoneda Zen is the vocalist while Sugimoto Ryo is the biwa player. Because Ryo didn't feel that his guitar sounded Buddhist enough, he instead uses an electric Biwa. Zen, who was trained as a monk, wields a shakujō, a Buddhist ringed staff which is meant to be used in prayer, as a microphone.

Both are able to combine their music with Furyoku to perform various feats. Zen is able to charge his voice with Furyoku in order to chant and send spirits to heaven and Ryo can charge his melodies to create an Oversoul.

Spirit

 * See More: Chimimoryo

These ghosts are thousands of small animal, bird and insect spirits that inhabit the mountain, who can't remember their original form. The BoZ brothers creates these Oversouls with their song "Chimi-Chimi Moryo", by using small rocks

Past
Once, the brothers were just a simple musical duo who played Buddhist Hard-Rock that was hated by their master. They became popular due to their catchy tunes and their unique appearances, and their first song "Joh! Butsu - Sankiemon" even made it to 49th place in the charts. Hao showed up at their monastery and offered them the ability to become shaman, which the BoZ accepted.

Five years before the Shaman Fight when Bill Burton is introduced into the group,the brothers who at the time were known as BOØWZ showed up late and questioned if Bill is the newbie who had just arrived, asking him if he was prepared to bite the dust. however Bill glared at them and revealing his spirits thus frighten them, however Brocken advises them not to mess with Bill if they valued their lives.

Shaman Fight in Tokyo
Not much is known about their time in the First Round, but they both were able to pass by hitting a Patch Officiant at least once, as well as winning at least two battles to advance to the second round. The BoZ attacked Yoh and Tamao as Yoh had attempted to return home quickly before heading out to China to save Ren, under the orders of Hao to try to take Yoh out of the Shaman Fight. They were successful in sending Amidamaru, Ponchi, and Konchi away to heaven, and continued to launch wave after wave of Chimimoryo to attack Yoh, until he was saved by the untimely arrival of Ryu who easily destroyed the Chimimoryo and defeated the BoZ brothers. Later they were seen with Hao prior to taking off on the Patch Plane, and would sit with their allies once they had boarded it, as well as subsequently riding on the airborne Spirit of Fire with Hao and the others, when dumped from the plane. The duo were eventually able to make it to the Patch Village, and formed up to make a three man team, with Peyote as their leader, dubbed Tsuchi-Gumi.

Shaman Fights Second Round
Team "Tsuchi-Gumi" faced Team "The Ren" which consisted of its leader Ren, Chocolove, and Horohoro in the first match of the Second Round. The BoZ quickly launched an assault of Chimimoryo when the match started, but were quickly knocked out by Chocolove's shaft attack. Peyote would then oversoul the BoZ with his spirits, forcibly despite their bodies being too worn out to fight themselves. Chocolove tried to avoid attacking them directly, but would come across difficulty in fighting his opponents who he didn't want to hurt, when Peyote oversouled the BoZ brothers to create a cactus like weapon on each arm that fired numerous furyoku thorns. Chocolove eventually used his Ayers Rock Sunrise and managed to force the spirits that were oversouled into the BoZ brothers to laugh and leave their bodies. After Chocolove was rendered unconscious, Ren quickly finished off Peyote and sealed a victory for his team, eliminating the BoZ brothers and Peyote from the competition.

After their defeat, the BoZ brothers appeared before Yoh and his friends and reveal that they have given up being followers of Hao, and recall to them how they came into contact with him. Thanking yoh for allowing them to realize the error of their ways, they take off once again going after their passion; with a career in music.

Later on, during Team Myou match with Team "The Ren", it's revealed they had joined the Gandhara, where Sati thanked them for helping reveal the identity of the five Elemental Warriors. However both brothers claim it was nothing to what she did for them, saying it was her who saved them, claiming they were grateful and at her service.

Invading The Plants
After Hao becomes Shaman King, the BoZ brothers are seen inside the Great Spirit, alongside the other members of the Gandhara.

Anime/Manga Differences
In the anime, their names are changed to Ryo Kamishiro and Zen Hijiri. Their appearances are slightly different from the manga.

Additionally, in the anime, they do not fight Team "The Ren" with Peyote Diaz in the tournament. Instead they and Peyote attacked the group on the day they met Chocolove McDonell. They were also controlled by Peyote's Oversoul from the very beginning of the fight.
