RISE Super Flyweight (-53 KG) champion {Kazuki Osaki} announced at a Tokyo press conference on Monday that he has vacated his title to fight for the RISE World Super Flyweight title at a later date. First, he will fight on the GLORY x RISE Grand Prix card on December 21 in a non-title fight. His opponent is yet to be determined.
"I have decided to give up the belt that I have held for four years so that I can challenge the world," said Osaki at a press conference held in Tokyo on Monday. “I feel a little sad because I just defended [my belt], and I also feel a little sad to let it go because I was a champion alongside my brother Koki [Osaki]."
His brother Koki will be making his ONE Championship Debut against {Huo Xiaolong} on November 8.

{Jin Mandokoro} will fight {Ryu Hanaoka} at RISE 184 on December 15 for the newly vacated belt.
