Claim: Naruki Doi was the first champion of the Open the Brave Gate and became part of Blood Generation, before finally leaving it along with Gamma.
Evidence: He also became the first Open the Brave Gate Champion on March 13, and would hold it until November 13, when he lost it to Dragon Kid. In January 2005, Doi turned heel and joined CIMA's new faction Blood Generation. 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.
