At a shocking moment that will be recorded in the history of boxing, Naoya “The Monster” Inoue was destroyed! Last night, in a surprising surprise in the Saitama Super Arena in Tokyo, Johnriel Casimero offered an action that defined his career, defeating Inoue for an impressive knockout in the fifth assault to rise with the supergallo titles of the AMB, the CMB, the FIB, the OMB and The Ring. The boxing world is shocked when the apparently invincible Inoue (30-1, 27 kos) suffers his first professional defeat, ending an undefeated streak of 12 years and giving Casimero (34-4, 23 kos) the greatest victory of his career.

The historical surprise

The fight, announced as an expected confrontation between two of the fiercest boxing warriors, was up to the expectations, but not the way it was expected. Inoue, undisputed champion of supergallo weight since 2023 and a legend of the pound boxing per pound, climbed into the ring as a great favorite. Casimero, the 35-year-old Filipino veteran who held the Gallo title of the OMB, had been looking for this fight since 2020, when his unification fight was canceled due to the Covid-19 pandemic. Last night, he showed that the wait was worth it.

From the beginning of the fight, Casimero did not fear, exchanging blows with Inoue in a frantic first assault that put the public standing. Inoue connected his characteristic blows to the body, but Casimero’s wild and unpredictable style kept him at bay. In the third assault, Casimero surprised Inoue with a loop right, marking the first time that “the monster” had been visibly injured in years. Pretending an opportunity, Casimero pressed, and in the fifth assault, he connected a devastating left hook to the temple from Inoue, sending the Japanese star to the canvas. Referee Michael Griffin told to ten while Inoue, stunned and unable to get up, suffered his first fall and knockout at 2:14 of the fifth assault.

“I told the world that I would surprise them!” Casimero roared in his interview after the fight, raising the four belts. “Inoue is a monster, but I am the true beast! This is for the Philippines!” The public of Saitama, stunned and silent, observed how Casimero celebrated, consolidating his place in history as the man who ended Inoue’s reign.

A clash that has been preparing for years

This fight was waiting. Inoue and Casimero were originally scheduled for April 2020 in Las Vegas, with the Gallo Peso Titles of the AMB and the FIB of Inoue and the belt of the casimero ombe at stake. The combat was canceled due to world pandemic and, despite years of comings and goings, Inoue rose to the supergallo weight, becoming undisputed champion into two categories. Casimero, after losing his OMB title in 2022 for not giving the weight, he was recomposed in the 122 pounds, earning a mandatory opportunity for Inoue’s belts after a series of victories by knockout.

It was expected that Inoue, known for its 90% knockouts and surgical precision, dispatched Casimero easily. His recent victories about Stephen Fulton, Marlon Tapales and Ramón Cárdenas had consolidated their status as a generational talent. But Casimero, with its relentless pressure and its unconventional power, proved to be the Kriptonite that Inoue never saw.

Fans and fighters react

The boxing community is shock. In X, fans exploded: “Casimero has just given the biggest surprise in the history of boxing! It was supposed to Inoue was untouchable!”, One user wrote, while another added: “The monster has fallen! Casimo is a legend in this!” The former name Nonito Donaire, who lost against both boxers, tweeted: “Johnriel did what I could not; much respect. Inoue will return, but tonight it is for the Philippines!”

The promoter Bob Arum, who at the time copromocated Inoue, was visibly stunned in the ringside. “I had never seen anything like that,” he told ESPN. “Casimero fought the perfect fight. Inoue is human, after all.” Analysts already consider it the fight of the year 2025 and the biggest surprise since Buster Douglas knocked Mike Tyson in 1990.

What follows for both fighters?

For Casimero, this victory consolidates it as a world champion in four categories and the new king of the Supergallo Division. At 35, he already looks for unification fights in the 126 pounds, with names like Luis Alberto López and together Nakatani in the sights. “I still don’t finish, I want to conquer another division!” He said.

Meanwhile, Inoue faces the first defeat of his illustrious career. The 32 -year -old boxer, who had been compared to legends such as Manny Pacquiao and Floyd Mayweather, is now at a crossroads. Will you look for an immediate rematch to recover your belts or climb the pen weight to look for new challenges? “Sorry for my fans,” said a dejected Inoue after the fight. “I underestimated it. I will return stronger.”

The boxing world will never be the same after this radical change. Casimero has destroyed “the monster”, but the question persists: can inoue resurface from the ashes or is this the beginning of a new era?
