Rin Nakai (9-0) captured the inaugural Valkyrie open-weight title with a doctor stoppage win over Mizuho Sato in Tokyo on Sunday. The former gymnast battered Sato with knees from the clinch, causing a possible orbital fracture which forced the ringside physician to halt the action at the end of the first round. Nakai stated before the fight that, were she to win the title, she'd like to compete in the U.S. at 125 or 135 pounds. In the main event, featherweight champion Mei "V-Hajime" Yamaguchi retained her title by drawing with Kyoko Takabayashi after three rounds. Photo by Sportsnavi.
