Rifdean arrives in Tokyo on a five-fight winning streak, having established himself as one of the most dangerous finishers in ONE’s Friday Fights series.

Rifdean comes out aggressively, looking to disrupt Nadaka’s rhythm with his attacking combinations. The he mixes his strikes with kicks and spinning attacks, showing that he is willing to take risks against the champion. At one point, Rifdean launches a spinning backfist that clips Nadaka and briefly puts the Japanese star under pressure. Nadaka responds with composure and precision. When Rifdean steps forward with a left hook, the champion answers with a left hook of his own, sending the challenger to the canvas for an eight-count. Rifdean manages to recover and continues fighting, but Nadaka’s sharp counterstriking makes the difference in a competitive opening round.
Rifdean returns for the second round determined to build on his attacking approach. He attempts to create an opening with a push kick aimed at Nadaka’s stomach, but the Nakasa sidelines the strike. As Rifdean looks to follow up with another spinning backfist, Nadaka reads the movement and evades the attack. He immediately counters, rotating his body into a lightning-fast left head kick that wraps around Rifdean’s neck. The strike lands cleanly, leaving Rifdean visibly hurt as he falls to the canvas. The referee immediately steps in to stop the contest at 0:58 of the second round, handing Nadaka a spectacular TKO victory.
