In December 2009, Tsukushi, then only twelve years old, and nine-year-old Kurumi began training professional wrestling under Emi Sakura at her promotion Ice Ribbon's dojo in Saitama. Tsukushi's training sessions with Sakura mainly took place on weekends, while on weekdays she remained in her hometown of Kamisu, training amateur wrestling with a local male junior high school wrestling team.[1] In January 2010, Tsukushi and Kurumi were entered into a trial series, which saw them both compete in three-minute time limit matches at Ice Ribbon events with those in attendance being given the right to vote on which one should be made a permanent member of the roster; the first to reach 500 votes would win the series.[6] Tsukushi made her professional wrestling debut on January 16, when she wrestled Chii Tomiya to a three-minute time limit draw.[5] During the next two months, Tsukushi also wrestled Emi Sakura twice,[7][8]Mai Ichii three times,[9][10][11] and Chii Tomiya and Hamuko Hoshi both once to a time limit draw,[12][13] before suffering her first loss on March 6, against Miyako Matsumoto.[14] On March 13, Tsukushi and Kurumi were defeated in a tag team match by Chii Tomiya and Riho.[15] After the match it was announced that Tsukushi had won the trial series 506 fan votes to 379 and had as a result earned the right to become a member of Ice Ribbon's roster.[15] The following day, she was defeated by Chii Tomiya in her official debut match.[1][16] Tsukushi earned her first win on April 29, when she pinned Tomiya in a tag team match, debuting her finishing maneuver, Harukaze ("Spring Breeze"), in the process.[17] On May 22, Tsukushi broke the record for the fastest win in Ice Ribbon history, when she pinned Emi Sakura in just five seconds.[18] The win earned her a shot at Sakura's ICE×60 Championship, Ice Ribbon's top title, however, she was defeated in the title match on June 5.[19] On July 11, Tsukushi made her debut for the NEO Japan Ladies Pro Wrestling promotion, losing to fellow Ice Ribbon worker Makoto.[20] Tsukushi's first year in professional wrestling ended with her biggest match yet, when she teamed with Natsuki☆Taiyo and Sayaka Obihiro on December 29 in a 24-minute main event, where they were defeated by Emi Sakura, Nanae Takahashi and Yoshiko Tamura.[21]
On March 22, 2011, Tsukushi entered a tournament to crown the first ever Internet Wrestling 19 Champion; a title contested for exclusively on Ice Ribbon's Ustream program 19 O'Clock Girls ProWrestling.[22] After defeating Mochi Miyagi in her opening match, Tsukushi advanced to the finals, where she managed to score an upset win over the reigning ICE×60, International Ribbon Tag Team and Triangle Ribbon ChampionTsukasa Fujimoto, winning her first title and becoming the inaugural IW19 Champion.[22] On March 31, Tsukushi made her debut for Smash at Smash.15, where she teamed with Hikari Minami and Riho to defeat Emi Sakura, Makoto and Mochi Miyagi in a six-woman tag team match.[23][24] On April 10, Tsukushi defended the IW19 Championship for the first time in a special episode of 19 O'Clock Girls ProWrestling, which aired live from the Kashimagakuen High School (ja) in Tsukushi's home prefecture of Ibaraki. The title defense against Emi Sakura ended in a nineteen-minute time limit draw, which meant that Tsukushi retained her title.[25] Five days later, Tsukushi successfully defended the title against Makoto at an Ice Ribbon and Osaka Pro Wrestling co-promoted episode of 19 O'Clock Girls ProWrestling.[25] The following day, Tsukushi and Riho unsuccessfully challenged Emi Sakura and Ray for the International Ribbon Tag Team Championship.[26] Also in April, Hikari Minami and Riho began producing their own professional wrestling events under the banner of "Teens", which also became the name of the informal stable, which in addition to the two also included Tsukushi, Dorami Nagano and Kurumi.[27] On April 24, Tsukushi was defeated by Riho in the main event of Teens.1.[28] As a result of pinning Tsukasa Fujimoto in the IW19 Championship tournament final, Fujimoto agreed to defend the ICE×60 Championship against Tsukushi. The title match took place on May 5 in the main event of Golden Ribbon at Korakuen Hall, where Fujimoto retained her title.[29][30][31] On May 13, Tsukushi made her third defense of the IW19 Championship, defeating Chii Tomiya.[32] On May 27, she lost the title to Hikari Minami in her fourth defense, ending her reign at 66 days.[32]

After defeating the team of Kurumi and Ray in the first round and former champions Muscle Venus (Hikaru Shida and Tsukasa Fujimoto) in the semifinals, Tsukushi and Toyota were defeated in the finals by Ice Ribbon's rival promotion Sendai Girls' Pro Wrestling representatives Dash Chisako and Sendai Sachiko.[42]
Before leaving Ice Ribbon, Toyota suggested that Tsukushi should form a new tag team with Tsukasa Fujimoto; the two followed the suggestion and dubbed their new team "Dropkickers".[43] On October 15, Dropkickers wrestled Chisako and Sachiko to a twenty-minute time limit draw; as a result, the title was once again declared vacant.[44] The following day, Tsukushi defeated Riho to earn the right to represent Ice Ribbon at Sendai Girls' Joshi Puroresu Dantai Taikou Flash tournament, a single-elimination tournament, where different joshi promotions battled each other.[45] On October 27, Team Ice Ribbon (Tsukushi, Emi Sakura, Hikari Minami, Hikaru Shida and Tsukasa Fujimoto) was eliminated from the tournament in the first round by Team Sendai Girls' (Meiko Satomura, Dash Chisako, Kagetsu, Miyako Morino and Sendai Sachiko), when Tsukushi was pinned by Chisako.[46][47] On December 2, Tsukushi defeated Kurumi to regain the IW19 Championship.[48] The rivalry between Ice Ribbon and Sendai Girls' culminated on December 25 at RibbonMania 2011, where Tsukushi and Emi Sakura faced Meiko Satomura and Sendai Sachiko in a match for the vacant International Ribbon Tag Team Championship. Tsukushi won the match for her team and Ice Ribbon by pinning Sachiko, thus winning the International Ribbon Tag Team Championship for the first time.[49] However, as Sakura had announced just prior to the match that she would be leaving Ice Ribbon the following month, her and Tsukushi's reign lasted only three days before they lost the title to Hikaru Shida and Maki Narumiya.[50] On January 7, 2012, Tsukushi defeated Sakura in her Ice Ribbon farewell match.[51]

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.[54][55] On February 5 at Yokohama Ribbon, Tsukushi and Fujimoto defeated Shida and Maki Narumiya to become the new International Ribbon Tag Team Champions.[56] Tsukushi and Fujimoto made their first title defense on March 20 at Ice Ribbon March 2012, defeating the team of Kurumi and Manami Toyota.[57][58][59] Three days later, Tsukushi lost the IW19 Championship to Kurumi in her first defense, ending her second reign at 112 days.[60] 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.[61] Tsukushi and Fujimoto regained the title from the Happy Makers on June 17 at Ice Ribbon's sixth anniversary event.[62] 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.[63] 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.[64]

They were, however, given a bye directly to the semifinals of the tournament.[78] After defeating BBA38 in their semifinal match, Tsukushi and Kurumi lost the International Ribbon Tag Team Championship to Muscle Venus (Hikaru Shida and Tsukasa Fujimoto) in a final match, which was also contested for the Reina World Tag Team Championship.[78] On December 31 at RibbonMania 2012, Tsukushi and her other Seishun Midori partner, Aoi Kizuki, defeated Kyoko Kimura and Sayaka Obihiro to win not only the International Ribbon Tag Team Championship, but also the Reina World Tag Team Championship, a title owned by the Reina X World promotion.
