Kishiwada would bring one of his running buddies from Osaka Pro, Gamma, into Blood Generation to be his replacement while he was out nursing his injury. However, Gamma and CIMA clashed, and this resulted in Blood Generation splitting in half, with CIMA leading a smaller face faction, and Naruki Doi and Gamma leading a heel faction. Doi's faction would win the rights to the name Blood Generation, but they immediately renounced it, instead renaming themselves the Muscle Outlaw'z. Upon his return, Kishiwada allied with the MO'z.
