Afterwards, Narumiya went on a seventeen match losing streak, before finally defeating Miyako Matsumoto on November 28, debuting her new finishing maneuver, the "Yuruneba", in the process. On December 8, Narumiya defeated Hikaru Shida and Tsukushi in a three-way match to become the number one contender to ICE×60 Champion Mio Shirai at Ice Ribbon's biggest event of the year, "RibbonMania 2012". At the event on December 31, Narumiya defeated Shirai to win the ICE×60 Championship for the first time. Narumiya wrestled her first match since her title win on January 5, 2013, pinning Hikaru Shida in a tag team main event, where she and Hamuko Hoshi faced Shida and Oz Academy representative Aja Kong. Following the match, Narumiya began complaining about severe neck pain and two days later Ice Ribbon announced that she had suffered a spinal cord injury and would be sidelined indefinitely. As a result of her injury, Narumiya vacated the ICE×60 Championship on January 12, ending her reign at just twelve days, the shortest reign in the title's history. Narumiya returned to Ice Ribbon on June 15, announcing that she had moved back to Tokyo from Kumamoto to start training for her upcoming return match. Narumiya wrestled her return match on August 25, losing to N3 stablemate Neko Nitta. She picked up her first win since her return on September 22 over Risa Sera. On October 6, Narumiya made her debut for Wrestle-1, losing to Akino in a singles match. Back in Ice Ribbon, Narumiya started a storyline rivalry with Mio Shirai, which built to a singles match on December 7, where Narumiya was victorious. Following the win, Narumiya was named the number one contender to the renamed and now weight limitless ICE×∞ Championship at "RibbonMania 2013". Prior to the match, Narumiya entered a storyline, where she was coaxed into giving up the guillotine leg drop finisher by the defending champion, Tsukasa Fujimoto, who claimed she could not defeat her without the move. Narumiya had earlier claimed that the move had caused her spinal cord injury a year earlier. On December 31, Narumiya failed in her title challenge against Fujimoto. During the match, Narumiya hit the guillotine leg drop, but in storyline hurt herself with it more than her opponent, leading to her losing the match.
