マグニチュード岸和田
On April 12, 2006, when Gamma was kicked out of Blood Generation due to constant clashes with CIMA, Doi left with Gamma, along with Masato Yoshino and Naoki Tanizaki. It was unclear whether Doi or Gamma was the leader of the splinter faction. After Doi and Gamma won the rights to the Blood Generation name in a tag match against CIMA and Don Fujii eleven days later, Doi's faction renounced it, renaming themselves the Muscle Outlaw'z. The MO'z ranks would grow when Magnitude Kishiwada joined them after returning from a stint of injury, as well as referee Kinta Tamaoka. The group would lose Tanisaki later that year, but shortly after recruited Genki Horiguchi. MO'z would also host any heel wrestlers visiting Dragon Gate.
