He would lose the title two months later to SUWA, and in that match, he suffered a bad knee injury that put him out of action for the remainder of the year.

On October 28, after Magnum TOKYO dissolved M2K, he announced that he and the remnants of M2K were the real Do FIXER, and that Darkness Dragon - now renamed K-ness - was still a member of the group and was sent into the home army (Seikigun) to cause problems within it.

[7] When Dragon Kid returned in early 2007, Saito decided to end Do FIXER activity following the betrayal of Genki Horiguchi, and brought him along into CIMA's new Typhoon stable.

When CIMA was out injured in mid-2008, Dragon Kid formed a team with Shingo Takagi for that year's Summer Adventure Tag League Tournament.

The team proved very successful, even making it to the finals, but they lost out to the previous year's winners Naruki Doi and Masato Yoshino.

[8] On December 28, he, Ryo Saito and Susumu Yokosuka fought a Unit Split Survival Three-Way Six-Man Tag Match against teams from WORLD-1 and Real Hazard, and they lost, bringing about the end of Typhoon.

After Akira Tozawa interrupted an Ultra Hurricanrana attempt in a six-man tag match on January 11, 2010, causing them and YAMATO to lose, Kid decided to leave KAMIKAZE and side with CIMA, Gamma Susumu Yokosuka and KAGETORA in the WARRIORS-5 group, and by default the Veteran-gun.

[2] Dragon Kid turned heel on January 14, 2011, along with the rest of WARRIORS, when they attacked Masato Yoshino and World-1, and joined forces with Naruki Doi's group.

[9] On May 15, the rest of Blood Warriors turned on Dragon Kid and kicked him out of the group, despite the fact that he still held the Open the Triangle Gate Championship with CIMA and Ricochet.

[10] On June 19 Dragon Kid gained a measure of revenge on Blood Warriors, when he and PAC defeated Ryo Saito and Genki Horiguchi to win the Open the Twin Gate Championship.

On August 17, 2014, Dragon Kid and Masaaki Mochizuki quit Oretachi Veteran-gun to form a new stable with BxB Hulk, which on September 9, 2014 would be named Dia.HEARTS.
