ONE Championship kicked off a historic event at the Ryogoku Kokugikan in Tokyo with ONE: CENTURY PART I.

Reigning ONE Women’s Atomweight World Champion Angela Lee retained her world title, submitting challenger and ONE Women’s Strawweight World Champion Xiong Jing Nan with a rear naked choke.

The first round of the main event at ONE: CENTURY PART I saw solid action transpire with both women having their moments.

Xiong punished Lee with crisp boxing combinations but Lee took it well. Lee, on the other hand, landed a couple of solid right hands and looked constantly for the clinch.

In the second frame, Lee continued to pursue the takedown, in an attempt to bring the action to the ground.

She began to dominate with her high-level grappling in the third, as Xiong started to wilt under pressure. In the fourth round, Xiong battled back brilliantly behind her jab-straight combination.

But Lee would not back down, firing combinations of her own. In the final round, Lee executed an explosive belly-to-back suplex to bring Xiong to the canvas.

Moments later, Lee took the back and sunk in a rear naked choke to force the tap.

In the ONE Flyweight World Grand Prix Championship Final, Demetrious “Mighty Mouse” Johnson of the United States overcame a strong effort from the Philippines’ Danny “The King” Kingad to win by unanimous decision.

In the first round, Johnson was relentless with his takedowns, showcasing his chain wrestling skills to constantly bring Kingad to the mat.

Kingad tried his best to defend against Johnson’s advances, but Johnson slowly started to dominate. In the second, Johnson continued with his amazing work from top, attacking with various submissions from different control positions.

In the third round, Johnson effortlessly outmuscled Kingad to cruise to the final bell. All three judges scored the bout in favor of Johnson, as the American captures the ONE Flyweight World Grand Prix Championship.

In the ONE Lightweight World Grand Prix Championship Final, reigning ONE Lightweight World Champion Christian “The Warrior” Lee of Singapore delivered a virtuoso performance, dominating Saygid Guseyn Arslanaliev of Turkey over three tough rounds.

It was a close and competitive first round, with Arslanaliev attacking with powerful punch combinations. Lee, on the other hand, found success in taking his opponent down and scoring with ground-and-pound.

In the second round, Lee capitalized on an exhausted Arslanaliev, piling on unrelenting punishment from top position. In the third round, Lee continued his dominance, pouncing on Arslanaliev, who could do little more than defend from the onslaught.
