真霜拳號
In 2005, under the guidance of former Far East Connection manager, 296, Kengo Mashimo formed a stable along with KAZMA called Kinnoutou and Kinnoutou started to dominate, eventually taking in Ryota Chikuzen and Kunio Toshima as well. Mashimo and KAZMA though were the most successful of the group, Mashimo going undefeated from the formation of Kinnoutou and did not drop a fall until well after he left the group. Kengo Mashimo and KAZMA won the first Strongest-K Tag Team tournament and were crowned the first ever Strongest-K Tag Team Champions, the two dominating the tag team scene in K-DOJO as they also won the UWA and UWF Intercontinental Tag Team titles, absorbing them into the STRONGEST-K Tag Team title. When K-DOJO split its roster into two, Mashimo, along with the rest of his Kinnoutou allies were drafted to GET. Mashimo's singles dominance was also highlighted with winning the STRONGEST-K '05 tournament, defeating Yuji Hino in one of the longest singles matches in K-DOJO history.
