In submission grappling, the 24-year-old Reis moves up a division to face the 27-year-old Takahashi in a high-level technical matchup.

A two-time ADCC World Champion, Reis has established himself as one of the world’s most dangerous grapplers since making his ONE debut against Shoya Ishiguro in March 2025, submitting him via kimura.

He captured the ONE Flyweight Submission Grappling World Title in December last year by defeating Daiki Yonekura.

With a 94-9 career record, Reis seeks his third consecutive promotional victory against his third Japanese grappling opponent.

Takahashi makes his ONE debut in the challenging position of facing a reigning World Champion. A career-defining performance will be required to derail “Baby Shark’s” momentum.

In bantamweight kickboxing action, 40-year-old Petchtanong faces 31-year-old Woolliss in a clash between World Championship experience and dangerous momentum.

Petchtanong, representing Superbon Training Camp, brings a 359-57 professional record with three ONE victories against two losses. The former ONE Bantamweight Kickboxing World Champion has defeated two former divisional kings in Hiroki Akimoto and Alaverdi “Babyface Killer” Ramazanov.

Woolliss announced his arrival on the global stage with a TKO win over former ONE Bantamweight MMA World Champion John “Hands of Stone” Lineker via calf kick in his debut.

Now he moves down a division with a 30-6 career record to face Petchtanong — a true test of whether his debut success translates against world-class kickboxing competition.

In lightweight MMA, 33-year-old Rasulov faces 26-year-old Gabriel, with both fighters chasing a path toward title contention.

Rasulov brings a 14-1 record and made an immediate impact in his ONE debut by dismantling former ONE Lightweight MMA World Champion Ok Rae Yoon. That dominant victory earned him a shot against ONE World Champion Christian “The Warrior” Lee in 2024, though an accidental eye poke led to a no-contest result.

In the 2025 rematch, Rasulov suffered a TKO loss to Lee — his first professional defeat — creating urgency to return to winning form.

Gabriel brings an 11-1 record and four victories since his ONE debut, most recently defeating Russia’s Magomed Akaev in February.

This lightweight collision pits Rasulov’s experience at championship level against Gabriel’s perfect promotional record and hunger for a title shot of his own.

Finally, 38-year-old former ONE Strawweight MMA World Champion Saruta faces 34-year-old Henrique in a strawweight MMA bout, with a rejuvenated career trajectory providing plenty of motivation for both men.

Saruta carries the weight of history into this matchup. The Tokyo native dethroned Pacio to claim the ONE Strawweight MMA World Title in January 2019, capping a rise from Japan’s domestic scene to the pinnacle of the global rankings.

However, Saruta surrendered the belt to Pacio in his first World Title defense and has since dropped three consecutive decisions, most recently falling to Keito Yamakita by split decision at ONE Fight Night 24, making a return to winning form essential.

Henrique arrives carrying the pressure of defeat as well, dropping his promotional debut against Lee Seung Cheol at ONE Fight Night 41 in March.

This strawweight collision pits Saruta’s pedigree and World Championship experience against the raw finishing power of a Brazilian determined to make his mark on the global stage.
