Mayumi Ozaki is a professional wrestler known for competing as a villainess at SHIMMER Women Athletes.
A veteran wrestler in her native Japan, Mayumi made her SHIMMER debut on October 18, 2014, defeating Saraya Knight in a No Disqualification match at SHIMMER 67. Mayumi turned heel later in the event, when she and Saraya attacked LuFisto following her victory over Rhia O'Reilly, who was Saraya's protege. The trio formed an alliance, and it was at SHIMMER 68 that Mayumi and Saraya defeated Kana and LuFisto in a tag team contest. At SHIMMER 69, the duo challenged Kellie Skater and Tomoka Nakagawa for the SHIMMER Tag Team Championship, only to end up on the losing end.
As part of her heel persona, the evil Mayumi demanded that all of her matches be contested under No DQ rules, and her first such match as a villainess saw her, Saraya, and Rhia victorious over Heidi Lovelace, Solo Darling, and Leva Bates at SHIMMER 70. Mayumi and Saraya lost a No DQ tag team contest to Heidi and Evie at SHIMMER 72 on April 11, 2015, but on the following day, Mayumi participated in an eight-woman tag team contest at SHIMMER 74 (her last SHIMMER appearance), winning with Aja Kong, Dynamite Kansai, Kyoko Kimura as her partners against Kellie, Tomoka, Misaki Ohata, and Hiroyo Matsumoto.
