Ryo Saito
Magnum returned to Japan and made his debut for Toryumon Japan on January 31, 1999. Magnum participated in the NWA World Middleweight Title Tournament but lost in the finals to SASUKE. During his early years in Toryumon he would align himself with wrestlers such as Dragon Kid and Kenichiro Arai to combat the factions of Crazy MAX and M2K. In March and April 2001, Magnum took part in El Numero Uno and was placed into block A. With three points he progressed to the semi final and then eventually the final which took place on April 4. In the final he took on M2K leader Masaaki Mochizuki where the match would end in a double count out, therefore the match would restart and this time Mochizuki would come out on top. On July 1, 2001 he defeated Mochizuki for the British Commonwealth Junior Heavyweight Championship and on August 14, he, Dragon Kid and Ryo Saito won the UWA World Trios Championship from Crazy MAX. On October 28, the trio lost the title to M2K. On March 15, 2002, Magnum lost the British Commonwealth Junior Heavyweight Championship to SUWA. In 2002's El Numero Uno, Magnum would this time defeat Mochizuki. In a shocking turn of events, on May 19, Magnum joined M2K and became their leader, on that night he teamed up with Mochizuki in a one night tag team tournament where they were defeated by Crazy MAX. On September 8, Darkness Dragon was kicked out of M2K and went on to form Do Fixer with Dragon Kid and Ryo Saito. On October 28, Magnum dissolved M2K and 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. It worked in that Ryo Saito was not welcomed back into Seikigun, but Dragon Kid, however, was. In El Numero Uno 2003, Magnum only reached the quarter finals before losing to Genki Horiguchi. On June 29, Magnum defeated CIMA for the Último Dragón Gym Championship and would lose it to SUWA on February 8, 2004. From the end of 2003, there were problems between Magnum and the remaining stable members again and again and on March 27, 2005, Magnum appointed Ryo Saito as the new leader. On March 28, Magnum joined PoS.HEARTS but was still considered a member of Do FIXER. Magnums first title shot since Toryumon became Dragon Gate came on May 1, for the Open the Triangle Gate Championship against Do FIXER. Magnum took part in King Of Gate 2005 but was eliminated in the first round by Masaaki Mochizuki. Magnum would leave PoS.HEARTS and formed a new stable called Renaissance and was still considered a member of Do FIXER.
