RIZIN 27 live from the Nippon Haishi Hall in Nagoya, Japan. The spotlight shines on Rizin women’s atomweight champion Ayaka Hamasaki. The 38-year-old Invicta and Deep Jewels veteran is among the best 105-pound ladies to ever grace a ring or cage, and she has yet to slow down. Hamasaki is 21-3 in more than 11 years of action. Two of her losses came in strawweight affairs against Claudia Gadelha and Livinha Souza. Her third stumble came in a recent trilogy fight with perhaps the only woman that can be considered her equal, Seo Hee Ham. Now, Hamasaki puts her belt on the line in a rematch against Kanna Asakura.
