Naruki Doi

On May 5, he made a notable defense of the title against the former sumo champion-turned-wrestler Akebono. Despite the huge size difference, he was able to defeat Akebono and retain the title, after hitting him with five consecutive Bakatare Sliding Kicks. On July 19, he got his biggest victory ever when he defeated Open the Brave Gate Champion CIMA in a Title vs. Title Match, claiming the Brave Gate for a second time and really cementing his status as the unquestioned ace of the promotion. He vacated the Brave Gate immediately afterwards. On August 24, 2010, Doi and Masato Yoshino won their third Summer Adventure Tag League by defeating Genki Horiguchi and Ryo Saito in the finals. On October 13, 2010, Doi turned on Yoshino and joined the former Deep Drunkers and Takuya Sugawara to form a new heel stable. On November 23, 2010, Doi and Gamma defeated K-ness and Susumu Yokosuka to win the Open the Twin Gate Championship. At the final Dragon Gate show of 2010, Final Gate 2010 on December 26, Doi unsuccessfully challenged his former partner Masato Yoshino for the Open the Dream Gate Championship. On January 10, 2011, Doi and Gamma lost the Open the Twin Gate Championship to Don Fujii and Masaaki Mochizuki. On January 14, 2011, Team Doi aligned themselves with CIMA's Warriors stable, who turned heel in the process. On January 18 the new group was named Blood Warriors. On September 2, Doi, Kzy and Naoki Tanizaki defeated Gamma, Masato Yoshino and YAMATO to win the Dragon Gate Open the Triangle Gate Championship. They were stripped of the title on January 19, 2012, after Tanizaki was sidelined for six months with a shoulder injury. After being kicked out of Blood Warriors by new leader Akira Tozawa, Doi reunited with Masato Yoshino to form World-1 International. On May 6, Doi, Yoshino and Pac won the Open the Triangle Gate Championship. On September 12, 2013, Doi again turned on Yoshino and jumped to Mad Blankey, signalling the end of World-1 International. On August 5, 2014, Doi became the interim Open the Dream Gate Champion, when he defeated BxB Hulk in a four-on-one handicap match. He failed to become the official champion, losing to Hulk in a one-on-one match on August 17. On June 13, Doi and YAMATO would defeat Masato Yoshino and Sachihoko Boy to become Open the Twin Gate champions. On August 16, 2015, Mad Blankey was forced to disband after losing to Jimmyz in a five-on-five elimination tag team match, after being betrayed by K-ness. On September 23, Doi formed a new stable named VerserK with Cyber Kong, Kotoka, Mondai Ryu, Shingo Takagi and Yamato. Doi and Yamato would hold the Open the Twin Gate championships until losing the titles to T-Hawk and Big R Shimizu on March 6, 2016. They'd break Mochizuki and Fujii's most defences record with 9 defenses before losing the belts. On October 12, 2016, VerserK turned on Doi after disbanding Monster Express and kicked him out of the unit. Doi subsequently became a tweener, and once again began teaming with longtime partner Masato Yoshino. Doi unsuccessfully challenged YAMATO for the Open the Dream Gate Championship at Final Gate on December 25. Doi refused a handshake from YAMATO after the match, and was helped to the back by two men wearing pink hoods over their heads. On January 18, 2017, Doi saved Masato Yoshino, Kotoka, and Ben-K from an attack by VerserK. A match between the two sides was then set for February 2. On May 4, Naruki Doi reunited with Masato Yoshino and formed a new unit called MaxiMuM with Big R Shimizu, Ben-K, and Kotoka.

Doi has also appeared for the Hawaii-based Action Zone Wrestling, debuting with tag team partner Masato Yoshino on January 7, 2008 in a four-way tag team match. He later returned for singles action at AZW's third anniversary show Anniversary Annihilation on June 2, 2008 in a triple threat match against Akua and Sabaki.

Doi continued to gain rank in 2007, and formed a regular tag team with Masato Yoshino, known as Speed Muscle, an amalgamation of their respective nicknames "Speed Star" and "Bosou Muscle". Doi and Yoshino declared themselves the first Open the Twin Gate Champions after winning the inaugural Summer Adventure Tag League Tournament in June, and later defeated Taku Iwasa and Kenichiro Arai for the I-J Heavyweight Tag Team Championship to unify the two belts. In November, Doi and Yoshino added the GHC Junior Heavyweight Tag Team Championship to their collection. Doi and Yoshino would drop the GHC titles to Shingo Takagi and BxB Hulk of New Hazard in January 2008, and then the Open the Twin Gate titles to Iwasa and Arai the month after, and opted to stop teaming with each other. Doi briefly teamed with Horiguchi while Yoshino pursued CIMA and the Open the Dream Gate championship. Yoshino put forward an impressive performance, and despite losing, was congratulated by both CIMA and Doi. Their team reconciled.

Doi became one half of the ROH World Tag Team Champions on March 3, 2007, with Shingo, beating The Briscoe Brothers in Liverpool, England. The two would lose the title back to the Briscoes at All Star Extravaganza III on March 30. In June 2008, he and Masato Yoshino joined Milano Collection A.T. and Puma to form Team Japan in that year's TNA World X Cup Tournament and together they had matches against members of the other teams, losing each match. At Victory Road, Doi competed in the Ultimate X match but came up short.

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.

In January 2005, Doi turned heel and joined CIMA's new faction Blood Generation. He gained more rank then, and rose to be something of a second-in-command for the stable. 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.

Doi continued on in Final M2K. At the end of 2004, he abruptly dropped the baseball gimmick and started competing under his real name.
