Naruki Doi
In August 2009, he and CIMA participated in the annual Summer Adventure Tag League Tournament, but they performed very poorly, winning only one match out of eight and finishing in last place. However, they would win the Open the Twin Gate Titles on December 29, beating champions Shingo Takagi &amp; YAMATO. Then, they strangely turned the belts in, declaring themselves to be only tentative champions, and announced their desire to face a strong team to determine the actual champions. On February 10, he and CIMA defeated Naruki Doi &amp; Masato Yoshino to become the full champions. On March 22 they lost the titles to Shingo and Cyber Kong. On May 13, 2010, Gamma, CIMA and Genki Horiguchi defeated Don Fujii, Masaaki Mochizuki and Akebono to win the Open the Triangle Gate Championship. On October 25, 2010, Gamma, CIMA and Horiguchi lost the Open the Triangle Gate Championship to Naoki Tanisaki, Yasushi Kanda and Takuya Sugawara. On November 13, Gamma betrayed WARRIORS by revealing his partner as Naruki Doi for his upcoming Twin Gate championship match at Gate of Destiny, joining Doi's unnamed unit. On November 23, 2010, Gamma and Doi defeated K-ness and Susumu Yokosuka to win the Open the Twin Gate Championship. They would lose the title to Don Fujii and Masaaki Mochizuki on January 10, 2011. On January 14, 2011, Doi's unnamed unit aligned themselves with the WARRIORS stable, who turned heel in the process. On January 18 the new group was named Blood Warriors. On May 27, the rest of Blood Warriors turned on Gamma and gave his spot in the group to Kzy. Gamma then went on to join Masaaki Mochizuki's Junction Three stable. On June 18, Gamma, Masato Yoshino and YAMATO defeated the Blood Warriors team of CIMA, Naruki Doi and BxB Hulk to win the vacant Open the Triangle Gate Championship. They would go on to lose the title to the Blood Warriors team of Kzy, Naoki Tanisaki and Naruki Doi on September 2. On January 21, Gamma was pinned in a six-man "Loser Leaves Unit" match and was as a result forced to leave Junction Three. After aligning with Kaettekita Veteran-gun, Gamma and stablemates HUB and Magnitude Kishiwada won the Open the Triangle Championship on October 21. They lost the title to Masato Yoshino, Naruki Doi and Shachihoko BOY just a month later. On June 14, 2015, he, CIMA and Don Fujii defeated the Jimmyz (Ryo "Jimmy" Saito, Genki Horiguchi H.A.Gee.Mee!!, and Jimmy Susumu) to win the Open the Triangle Gate Championship. On October 8, Gamma formed a new unit with CIMA, Eita, El Lindaman, Punch Tominaga, and rookies Takehiro Yamamura and Kaito Ishida. On November 1, the unit was named Over Generation. The same day, he, CIMA, and Don Fujii defended the Open the Triangle Gate Championship against the Jimmyz (Jimmy Susumu, Jimmy K-Ness J.K.S., and Ryo "Jimmy" Saito), and vacated the titles afterwards.
