Starlight Kid made her professional wrestling debut on October 11, 2015 in a three-way match in which she and Momo Watanabe lost to Kaori Yoneyama.[1] On November 8, she competed in her first major Stardom tournament, teaming up with Hiromi Mimura to compete in the 2015 Goddesses of Stardom Tag League.[citation needed] The team lost in the first round to Watanabe & Datura.[citation needed] After that, she would team up with Miura very often. Kid spent most of her matches losing to other, more experienced wrestlers, which would help put over other wrestlers while at the same time giving Starlight Kid some in-ring, televised, experience.
Starting in June 2016, Kid took a year long break from wrestling. She made her return on June 11, 2017.[2][3] In March 2018, she would participate in the tournament for the inaugural Future of Stardom Championship where she defeated Hanan in the first round and then she would defeat Shiki Shibusawa in the tournament final to become the inaugural Future of Stardom Champion, which was newly established at the Korakuen Hall Tournament, and became the first champion.[4]
As a result of the 2018 Stardom Draft on April 15, 2018, Starlight Kid formed a stable with Mayu Iwatani, Saki Kashima, Shiki Shibusawa, Natsumi, and Tam Nakano after she was revealed as their fifth pick with stable being later named STARS. On May 27, at Shining Stars, her first singles match with Io Shirai ended in defeat, but the audience highly praised it. Post-match, AZM challenged her for the Future of Stardom Championship, and on June 3 at Queen's Fes In Sapporo, the match went to a time-limit draw. From October 23 until November 4, Kid & Natsumi took part in the 2018 Goddesses of Stardom Tag League, finishing the tournament with a record of two wins, two losses, and one draw, failing to advance to the tournament finals.
On January 3, 2019, Kid lost her title to Utami Hayashishita at New Years Stars, ending her reign at 281 days. At Stardom Cinderella Tournament 2019 on April 29, she made it to the semi-finals where she fell short to Konami.[5]
After defecting Stars, Starlight Kid switched from her light-colored masks (left 2019 and center 2020) to a darker one (right, 2022) to depict her embracing the dark side of Oedo Tai. Her mask style, similar to the ones worn by Queen's Quest members until early 2022 was inspired by Tiger Mask.
Since Kawasaki Super Wars, the first event of the Stardom Super Wars trilogy which took place on November 3, 2021, Kid would enter in the quest to recruit more members into Oedo Tai which would lead to a feud with Momo Watanabe who would later be a victim of Starlight Kid's mind games as the latter's strategy to recruit members to Oedo Tai. First, Kid successfully defended the High Speed Championship against Watanabe on November 3.[14] At Tokyo Super Wars on November 27, she defended the High Speed title again against Koguma.[15] Kid's mind games against Watanabe eventually degenerated into an Eight-Woman Elimination Tag Team Match at in which both of them would be the captains of their respective teams. The loser captain would be forced to join the enemy unit and if Kid lost, she would also have to unmask and reveal her real name. The match took place on December 18, at Osaka Super Wars, the event which represented the last part of the "Super Wars" trilogy. With the match coming down to the wire and Queen's Quest holding a 2 to 1 advantage over Kid, a shocking moment occurred when Watanabe betrayed her Queen's Quest and hit her long-time tag team partner AZM over the head with a chair, handing the win to Oedo Tai and with Kid keeping her mask and Watanabe joining the stable.[16] At Stardom Dream Queendom, Kid once again defended the High Speed title successfully against AZM and Koguma in a three-way match.[17]
