Giriko is a Demon Weapon and an ally to the witch Arachne. He lives for fighting, and likes to be destructive. Giriko takes the form of a chain saw in weapon form. Although he is a weapon like Tsubaki or Soul, he openly states his hatred for Shibusen, claiming that he wants to follow his own path will rather than be used by a meister. Hence, he fights solo, using martial techniques while chains circle around his body. He also uses his chains as a form of transportation, like caterpillar treads on a tank. Giriko is not very good at remembering faces, as seen when he does not recognize Maka when she infiltrates into Arachne's castle with the other Shibusen students. He has formed a rivalry with death scythe Justin Law, as they both are weapons who fight without meisters. (Source: Wikipedia)

Ryoku (リョク, Ryoku) is a boy from Shin village, East Asia. He met Black Star as he and Tsubaki were looking for Masamune. It appears that Ryokou and/or his village has had dealings with the Star Clan in the past, as he recognized the tattoo on Black Star's arm, but he may just know that from the clan's reputation. At first believing Black Star was part of the Star Clan, he offers him money to leave before chasing him out of the village for fear he may attack them. However, it was that fear and the fear of not being powerful enough which allowed him to be possessed by Masamune. After Masamune was defeated, Ryoku comes to realize Black Star was not a member of the Star Clan but that still didn't mean that he liked him anymore than before.

Referred to as "Mole Hunter" Joe Buttataki, Joe makes his first appearance at the end of chapter thirty-seven of the manga when he is called to Shibusen to investigate the possibility of a spy. His name when literally translated is "kick the shit out of," a phrase he says at the end of chapter thirty-seven in the manga. He is able to detect the snake placed in Marie's body. He is the ex-boyfriend of Marie Mjolnir. Joe had apparently kept his distance from her, fearing that his "soul perception" may grow so powerful that he could see through her. Joe stated to Marie that he regretted his decision and asked her out for dinner. He considers his ability unpleasant since it only allows him to work a job where he can only mistrust his allies. Joe is the first technician to be able to pierce a witch's technique to appear human and his power is growing even now. -Wiki
