Miyako Matsumoto
Former dancer and alum of Ochanomizu University, Narumiya began training for a career in professional wrestling under Emi Sakura, who gave her the ring name "Narumiya" after the "Chronicles of Narnia" films. She made her debut on March 19, 2011, working for Sakura's Ice Ribbon promotion, losing to Mochi Miyagi. Just two days later Narumiya wrestled at her first major Ice Ribbon event, "Ice Ribbon March 2011", where she, Riho and Tamako faced Hikari Minami, Kurumi and Tsukushi in a six-woman elimination tag team match. Narumiya was eliminated from the match by Minami, after which her team was defeated, when Tsukushi pinned Riho. On April 20, Narumiya picked up her first win on April 20, defeating Miyako Matsumoto. Narumiya then teamed with Matsumoto at her second major event, "Golden Ribbon 2011" on May 5, where the two defeated Hamuko Hoshi and Mochi Miyagi, with Narumiya pinning Hoshi for the win. Narumiya's following months consisted mainly of losses, with her picking up her only wins against fellow newcomer Dorami Nagano. During June, Narumiya formed the N3 stable with Meari Naito and Neko Nitta, who debuted around the same time as her. N3 wrestled several matches together during the summer, but lost all of them, including three-on-one handicap matches against Hikaru Shida on June 8 and Tsukasa Fujimoto on June 15.
