After joining RAVE and winning the Strongest-K Championship, Mashimo started a rival partnership with the newly unmasked Madoka.
Mashimo's Kinnoutou past was brought back to him, defeating his ex-partner KAZMA in the main event for the 5th Anniversary show in April, then taking on Ryota Chikuzen for his title a few months later.
Once GET and RAVE merged, Mashimo kept his partnership with Madoka and brought Boso Boy Raito into their alliance, however never officially becoming a group.
2007 has also seen Mashimo start an interpromotional rivalry with BJW heavyweight Daisuke Sekimoto, the two fighting on nearly every Indy Summit show, culmulating in a BJW Tag Team Championship title match with Mashimo teaming with DDT star HARASHIMA in a 30-minute draw against champions Sekimoto and Pro Wrestling ZERO1-MAX's Yoshihito Sasaki.
On September 7, 2012, Mashimo began working for New Japan Pro-Wrestling, joining the Suzuki-gun stable, which also included his trainer Taka Michinoku.

[12] In early 2014, Mashimo began working regularly for All Japan Pro Wrestling (AJPW) as a member of Kenso's Dark Kingdom stable.
