Miyako Matsumoto
On January 8, Tsukushi took part in Bull Nakano's retirement event, participating in a special ten woman tag team match, where each team allegedly included wrestlers in their tens, twenties, thirties, forties and fifties. In the match, Tsukushi, Dump Matsumoto, Kyoko Inoue, Leon and Sawako Shimono defeated Cherry (the only wrestler in the match whose real age was not known publicly), Jaguar Yokota, Manami Toyota, Natsuki☆Taiyo and Tomoka Nakagawa. Back in Ice Ribbon, Tsukushi went on to form a regular tag team with Tsukasa Fujimoto. On January 14, Tsukushi pinned ICE×60 and International Ribbon Tag Team Champion Hikaru Shida in a tag team match, where she and Fujimoto faced Shida and Kurumi. On January 25, Fujimoto asked for a shot at the International Ribbon Tag Team Championship for the Dropkickers. The challenge was accepted by Shida, who then went on to avenge her loss to Tsukushi by defeating her in a non-title match four days later. On February 5 at "Yokohama Ribbon", Tsukushi and Fujimoto defeated Shida and Maki Narumiya to become the new International Ribbon Tag Team Champions. Tsukushi and Fujimoto made their first title defense on March 20 at "Ice Ribbon March 2012", defeating the team of Kurumi and Manami Toyota. Three days later, Tsukushi lost the IW19 Championship to Kurumi in her first defense, ending her second reign at 112 days. On May 5, Tsukushi and Fujimoto lost the International Ribbon Tag Team Championship to the Happy Makers (Aoi Kizuki and Sayaka Obihiro) in the main event of "Golden Ribbon 2012", ending their reign at 90 days. Tsukushi and Fujimoto regained the title from the Happy Makers on June 17 at Ice Ribbon's sixth anniversary event. On June 23, Tsukushi surprised Fujimoto after a tag team match and pinned her to win DDT Pro-Wrestling's Ironman Heavymetalweight Championship, taking advantage of a rule, where the champion could be pinned or submitted anytime and anywhere. Shortly afterwards, Tsukushi comically lost the title to one of Ice Ribbon's ring mats. On July 15 at "Sapporo Ribbon 2012", Tsukushi and Fujimoto lost the International Ribbon Tag Team Championship to Miyako Matsumoto and Neko Nitta in their first title defense.
