Isami Kodaka
As a sign of her growing status in Ice Ribbon, on January 16, 2010, Tomiya was chosen as the exhibition opponent for two debuting wrestlers, Kurumi and Tsukushi, both of whom would join Ice Ribbon full-time later in the year. On January 23, Tomiya and Riho were defeated by Miyako Matsumoto and Nanae Takahashi in a hardcore match, a match type rarely used in Ice Ribbon. While the match signaled the end of Tomiya's partnership with Riho, it was only the beginning of a storyline rivalry between Tomiya and Miyako Matsumoto. On June 17, Tomiya unsuccessfully challenged Matsumoto for the Triangle Ribbon Championship in a three-way match, which also included Tsukasa Fujimoto. On July 14 and 17, Tomiya scored back-to-back singles match victories over Matsumoto and her new tag team partner, deathmatch wrestler Jun Kasai. The victories led to a match on July 19, where Tomiya teamed with JWP Joshi Puroresu wrestler Command Bolshoi to unsuccessfully challenge Matsumoto and Kasai for the International Ribbon Tag Team Championship. Afterwards, Tomiya recruited deathmatch wrestler Isami Kodaka as her new tag team partner, and on August 7, the two defeated Matsumoto and Kasai to become the new International Ribbon Tag Team Champions. They would go on to lose the title to Gentaro and Mai Ichii on September 23. On October 30, Tomiya unsuccessfully challenged former partner Command Bolshoi for the ICE×60 Championship. On November 12, Tomiya, along with Emi Sakura, Hikaru Shida, Makoto, Sayaka Obihiro and Tsukasa Fujimoto, made an appearance at a press conference held by Smash to promote Sakura's upcoming debut for the promotion. The following month in Ice Ribbon, Tomiya began regularly teaming with former rival Makoto. On December 24, Tomiya made her debut for Smash at "Happening Eve", where she teamed with Hikari Minami and Kushida in a six-person tag team match, where they were defeated by Isami Kodaka, Makoto and Yusuke Kodama.
