Chii Tomiya

In February 2013, Micro, along with all other Japanese wrestlers affiliated with Reina X World, left the promotion. On September 20, the group announced they were forming a new promotion, named World Pro-Wrestling Association (WPA). At the promotion's inaugural event on December 31, Micro debuted under the new ring name Akubi (Japanese for yawn; written in Roman alphabets and stylized in all capital letters), pinning Bambi in a tag team match, where she and La Malcriada defeated Bambi and Tsubasa Kuragaki. She continued using the ring name Micro, when making appearances outside of WPA.

On January 4, 2011, Tomiya went through a complete character overhaul, debuting a new look, which included a black and blue two-piece outfit, a new entrance theme and the nickname "Black & Black", with Tomiya now becoming a full-blown villain. On January 15, Tomiya, along with Hikari Minami, Kurumi and Tsukushi became a part of Makoto's new Heisei YTR stable. After pinning ICE×60, International Ribbon Tag Team and Triangle Ribbon Champion Tsukasa Fujimoto in a non-title match on February 16, Tomiya was granted a shot at the ICE×60 Championship seven days later, but was again unsuccessful in her challenge. On March 21, Tomiya ended her long rivalry with Miyako Matsumoto, when she and Kazuhiko Ogasawara were defeated in a hardcore match by Matsumoto and Jun Kasai. On May 5 at Golden Ribbon 2011, Tomiya unsuccessfully challenged Sendai Girls' Pro Wrestling representative Kagetsu for the JWP Junior and Princess of Pro-Wrestling Championships. Eight days later, Tomiya unsuccessfully challenged Tsukushi for the Internet Wrestling 19 (IW19) Championship at an 19 O'Clock Girls ProWrestling event. After Hikari Minami became the new IW19 Champion, she offered Tomiya another shot at the title, which led to a match on June 1 at 19 O'Clock Girls ProWrestling's first anniversary event, where Tomiya defeated her to become the third IW19 Champion. Afterwards, Tomiya named her friend Makoto her first challenger for the title, which led to the two agreeing to a "best of nine" series. However, the series had to be cancelled, when Makoto was on June 8 sidelined with a neck injury. Instead, Tomiya went on to make her first defense on June 24, defeating Hikaru Shida. On July 2, Tomiya defeated Mochi Miyagi in the finals of a four-woman tournament to earn the right to represent Ice Ribbon in Smash's Diva Championship tournament. Five days later, Tomiya returned to Smash, confronting her first round opponent, Makoto, at a press conference and accusing her of turning her back on Ice Ribbon in favor of Smash. On July 15 at Smash.19, Tomiya was eliminated from the Smash Diva Championship tournament by Makoto. Back in Ice Ribbon, on July 22, an IW19 Championship match between Tomiya and Makoto ended in a nineteen-minute time limit draw. While the rules of the IW19 Championship stated that the champion retains the title in the event of a time limit draw, Tomiya instead chose to vacate the title afterwards. The reason for this was revealed the following month, when Tomiya announced that she, like Makoto, had decided to leave Ice Ribbon and try to broaden her capabilities as a professional wrestler by turning into a freelancer and opening doors to other promotions. Tomiya wrestled her final Ice Ribbon match on August 28, when she unsuccessfully challenged Hikari Minami for the ICE×60 Championship.

After leaving Ice Ribbon and becoming a freelancer, Tomiya dropped her old ring name out of respect towards Emi Sakura and her former home promotion, and adopted the new ring name "Micro". She made her first appearance as Micro on September 4, 2011, at an event held by the Happy Hour!! promotion, where she faced Keiko Aono in a losing effort. On September 11, Micro made her debut for the JWP promotion, teaming with Leon in a tag team match, where they were defeated by Kazuki and Sachie Abe. Later that same day, Micro appeared at a press conference, where she announced Pro Wrestling Wallaby as her new home promotion. On October 10, Micro made an appearance at a special JWP event, produced by Kaori Yoneyama, where she, working under the ring name "Micro Yoneyama", teamed with Bolshoi Yoneyama and Rabbit Yoneyama to defeat Jaiko Ishikawa in a three-on-one handicap match. Later that same event, Micro took part in a battle royal for the World Cosplay Championship, which was won by Misaki Ohata. On November 13, Micro wrestled her first singles match for JWP, defeating Moon Mizuki. On December 29, Micro faced Makoto at a Mr. Gannosuke-produced event in an "Ice Ribbon Alumni Showdown", which was won by Makoto. On January 9, 2012, Micro returned to JWP, defeating masu-me in a singles match. Six days later, Micro made her debut for the Osaka Joshi Pro Wrestling promotion, unsuccessfully challenging Sawako Shimono for the JWP Junior and Princess of Pro-Wrestling Championships. On April 20, Pro Wrestling Wallaby publicly fired Micro for "unprofessional behaviour" and "inappropriate remarks". On June 17, Micro returned to JWP, unsuccessfully challenging Rabbit Miu for the JWP Junior and Princess of Pro-Wrestling Championships. On July 7, Micro made her debut for Reina X World, when she teamed with Puchi Tomato in a tag team match, where they were defeated by Arisa Nakajima and Manami Katsu. At the promotion's following event on July 16, Micro defeated Tomato in what was billed as a "tryout" match. At Reina X World's event on August 26, Micro worked under a mask, similar to that of Puchi Tomato, and the ring name Mini Tomato in a match, where she defeated Charlie Simone Aussie. On September 9, Micro, as Mini Tomato, main evented her first Reina X World event, where she and Aki Kanbayashi defeated Leon and Manami Katsu.

As a sign of her growing status in Ice Ribbon, on January 16, 2010, Tomiya was chosen as the exhibition opponent for two debuting wrestlers, Kurumi and Tsukushi, both of whom would join Ice Ribbon full-time later in the year. On January 23, Tomiya and Riho were defeated by Miyako Matsumoto and Nanae Takahashi in a hardcore match, a match type rarely used in Ice Ribbon. While the match signaled the end of Tomiya's partnership with Riho, it was only the beginning of a storyline rivalry between Tomiya and Miyako Matsumoto. On June 17, Tomiya unsuccessfully challenged Matsumoto for the Triangle Ribbon Championship in a three-way match, which also included Tsukasa Fujimoto. On July 14 and 17, Tomiya scored back-to-back singles match victories over Matsumoto and her new tag team partner, deathmatch wrestler Jun Kasai. The victories led to a match on July 19, where Tomiya teamed with JWP Joshi Puroresu wrestler Command Bolshoi to unsuccessfully challenge Matsumoto and Kasai for the International Ribbon Tag Team Championship. Afterwards, Tomiya recruited deathmatch wrestler Isami Kodaka as her new tag team partner, and on August 7, the two defeated Matsumoto and Kasai to become the new International Ribbon Tag Team Champions. They would go on to lose the title to Gentaro and Mai Ichii on September 23. On October 30, Tomiya unsuccessfully challenged former partner Command Bolshoi for the ICE×60 Championship. On November 12, Tomiya, along with Emi Sakura, Hikaru Shida, Makoto, Sayaka Obihiro and Tsukasa Fujimoto, made an appearance at a press conference held by Smash to promote Sakura's upcoming debut for the promotion. The following month in Ice Ribbon, Tomiya began regularly teaming with former rival Makoto. On December 24, Tomiya made her debut for Smash at Happening Eve, where she teamed with Hikari Minami and Kushida in a six-person tag team match, where they were defeated by Isami Kodaka, Makoto and Yusuke Kodama.

On September 11, 2008, Tomiya moved from her hometown of Utsunomiya, Tochigi to Tokyo to begin training professional wrestling under Emi Sakura. Sakura gave her the ring name Chii Tomiya by combining the Japanese word chi (ち , chi) , which indicates smallness or quickness, with the name of her hometown Utsunomiya (宇都宮市 , Utsunomiya-shi) . After less than a month of training, Tomiya made her debut for Sakura's Ice Ribbon promotion on October 7, losing to her trainer 3–0 in a five-minute exhibition match. Tomiya made her "official" debut on October 18, losing to Yuki Ueda. For the first months of her career, Tomiya wrestled several matches against Makoto, always ending up on the losing side. Finally, on January 18, 2009, Tomiya picked up her first win, pinning Yuki Ueda in a tag team match, where she teamed with Minori Makiba and Ueda with Yoshiko Tamura. On February 7, Tomiya faced one of her idols, NEO Japan Ladies Pro Wrestling representative Tanny Mouse, in a losing effort. The match eventually led to a partnership between the two. On March 22, Tomiya made her debut for NEO Japan Ladies Pro Wrestling, during which she won her first championship, when she surprised Tanny Mouse and pinned her after a match to win DDT Pro-Wrestling's Ironman Heavymetalweight Championship, taking advantage of the title's rule, where a champion could be pinned anytime, anywhere. She would lose the title to Cherry later that same day. On June 3, Tomiya defeated nine other wrestlers to win a battle royal, her first accomplishment in Ice Ribbon. During 2009, Tomiya continued regularly wrestling Makoto, including losing to her on August 5 in a match to determine the number one contender to Ice Ribbon's top title, the ICE×60 Championship. Tomiya would eventually receive her first shot at the title on October 23, but was defeated by defending champion Emi Sakura. On November 14, Tomiya formed the tag team named Miniature Dachs with Riho, with the two defeating Hikari Minami and Mai Ichii in their first match together.
