Mika Akino

is a female Japanese joshi wrestler, signed to Oz Academy. Billed from Honshū, she started late in the sport and didn't debut until the age of 24. Trained by Mariko Yoshida, she proved to have an innate ring presence and excelled at the sport. After leaving AtoZ, AKINO joined with three other joshi wrestlers to form a new promotion. Her longtime friend Mariko Yoshida and fellow ARSION wrestler Michiko Ohmukai joined her, and rising star Momoe Nakanishi also jumped on board. The name of their promotion, M's Style, stemmed from the fact that all four women's first names started with the letter "M".

M's Style held its first show in April 2004. At the time, the promotion was thought to be the future of joshi puroresu, and had been rumored to be working with puroresu powerhouse New Japan Pro Wrestling. Nothing came of the partnership, and the promotion suffered another blow.
