According to this blog https://metogan.com/catfight-learning/yomoyama01/
"In 1990, at a secret club where only rich people could join, Mariko Itsuki and Nao Saejima , who were popular AV actresses at the time, had a naked fight over the prize money and a trip abroad . It seems that Nao Saejima won as a result of a fierce battle that both of them lost a lot of their hair. Mariko Itsuki, who lost her, had her nosebleed and was also bleeding from her left breast"
Thank you for sharing! Is there any secret footage or photos available? Or some written report or detailled account of the fight?
Would love to know more about the reasons, about the intensity of the fight and how Nao finished her opponent.
