At a press conference held by RISE on April 15, 2021, it was revealed that YA-MAN would face the seventh ranked RISE super-lightweight contender Yuma Yamaguchi at Rise on Abema 2 on June 15, 2021, in an "open finger glove" match. Both fighters competed in MMA gloves under this rule-set, in a three-round three-minute bout. There were no extension rounds, as is normal under the regular RISE rule-set and the fight could only end in knockout or technical knockout, any decision would result in a pre-determined draw. YA-MAN's fight with Yamaguchi was one of two such matches held at the event, with RISE representative Takashi Ito stating he would introduce an OFG belt and rankings, should it prove to be popular enough.[18]

During the press conference, YA-MAN revealed that he had volunteered to fight under this rule-set, although he remained respectful of his opponent, stating: "...I hope Yuma Yamaguchi is coming in with a mentality like 'If I lose to a guy like this [who's only been training for five years], I'm getting weaker, and it's probably best I retire soon'".[19]

YA-MAN had a poor start to the fight, as he was knocked down with a left hook in an exchange after managing to corner Yamaguchi. He continued pressuring when the fight action resumed and was able to rally back in the second round, as he knocked Yamaguchi with a left uppercut to a right hook combination. Yamaguchi was unable to beat the eight-count following the knockdown, forcing the referee to wave the fight off at the 1:53 minute mark.[20] YA-MAN stated his desire to fight the winner of the other OFG bout on the card, between Yuma's brother Hiroto and Yoshimichi Matsumoto.[21]

On August 24, 2021, several additional bouts were announced for Rise World Series 2021 Yokohama, which was scheduled to take place on September 23, 2021. Two of these bouts were "open fingers glove" fights, which saw Hiroto Yamaguchi faced Tatsuya Inaishi and YA-MAN face the second ranked RISE lightweight contender Tomohiro Kitai. The rule-set was slightly tweaked prior to the event taking place: fights which don't end in stoppage would no longer result in a pre-determined draw, but would be judged just the same as a fight which took place under the regular RISE rules.[22] On September 22, the two fighters were engaged in a brief onstage scuffle during the face-offs, in which Kitai initiated physical contact when he shoved YA-MAN.[23]

On fight night, YA-MAN won the fight by a first-round knockout. He knocked his opponent down with a left hook right hook combination, which floored Kitai and left him unable to beat the ten-count. It was the quickest stoppage victory of his career up to that point, as he needed just 43 seconds to knock Kitai out.[24] During his post-fight speech, YA-MAN called out Hiroto Yamaguchi, the brother of his previous opponent Yuma. He furthermore publicly called for an open finger glove tournament to be held by RISE.[25]

On September 24, 2021, a day after the RISE WORLD SERIES 2021 Yokohama event was held, YA-MAN called out Kan Nakamura over social media. Nakamura had entered the ring following RISE Lightweight champion Naoki Tanaka's non-title bout with Taiju Shiratori at the event and demanded a title fight with Naoki, who however refused, as he felt Nakamura hadn't earned it. YA-MAN felt the same way and instead offered to face Nakamura himself, in an open finger glove match.[26] The fight between YA-MAN and Nakamura was officially announced on October 13. It was scheduled as the featured bout of Rise World Series 2021 Osaka 2, which took place on November 14.[27] YA-MAN kept his undefeated record in OFG bouts, as he won the fight by unanimous decision. Although no fighter was able to knock the other down, YA-MAN was able to win two of the three rounds of all of the judges' scorecards, who scored the bout 29–28 in his favor.[28]
