Mio Shirai
On September 7, Tsukushi produced her first own Ice Ribbon event, which celebrated her sixteenth birthday and saw her lose to veteran wrestler Gami in the main event. From January 5 to March 16, 2014, Tsukushi took part in JWP's 2014 Tag League the Best, teaming with Rabbit Miu under the team name "Haruusagi" ("Spring Rabbit"; a combination of "Harukaze" and the Japanese word for rabbit, usagi). After two wins and one loss, the team won their round-robin block and advanced to the finals of the tournament. On March 16, Haruusagi defeated Mascara Voladoras (Leon and Ray) in the finals to win the 2014 Tag League the Best and become the number one contenders to the Daily Sports Women's and JWP Tag Team Championships. Tsukushi and Miu received their title opportunity on May 4, but were defeated by Command Bolshoi and Kyoko Kimura in a decision match for the now vacant titles. Meanwhile, back in Ice Ribbon, Tsukushi got involved in a storyline rivalry with Mio Shirai. After a two-year break, Ice Ribbon brought back the "Teens" concept on August 14 with Tsukushi as the new head producer. In the main event of "Teens8", Tsukushi and Rabbit Miu defeated International Ribbon Tag Team Champion Risa Sera and World Wonder Ring Stardom representative Takumi Iroha. On September 15, Tsukushi and Rabbit Miu unsuccessfully challenged Sera and Maki Narumiya for the International Ribbon Tag Team Championship. On December 14, Tsukushi made an appearance for Pro Wrestling Wave as part of "Young Oh! Oh!", Wave's equivalent of the Teens project, where she led the "East Japan Little Yankees" to a win over the "West Japan Giants" in a ten-woman main event tag team match, scoring the deciding pinfall over Rina Yamashita. On December 28 at Ice Ribbon's biggest event of the year, "Ribbon Mania 2014", Tsukushi unsuccessfully challenged her rival Mio Shirai for the Union Fly to Everywhere World Championship. On February 22, 2015, Tsukushi made her debut for World Wonder Ring Stardom, defeating Momo Watanabe.
