62 HxH: The Strongest Assassin

Zhengmei's eyes filled with disbelief at Kaizen's words.

"Little brat, stop bluffing. You'll be dead soon!"

But minutes passed, and Kaizen was still standing—unharmed, alive, and steady. Even the traces of poison on his hands had all but vanished.

"How... how is this possible?"

Zhengmei's confusion deepened. He knew how potent her poison was; countless targets, including seasoned Nen users, had succumbed to it. No ordinary person could resist it—certainly not for l...

61 HxH: The Strongest Assassin

"Trying to run?"

"No way in hell!"

Kaizen wouldn't give Zhengmei a chance to escape.

"Killer Queen!" Kaizen barked the command.

There was a deafening BOOM!

Keke's body flew through the air, eyes wide with disbelief.

A Moment Earlier...

After giving the Killer Queen orders to engage freely, Kaizen squared off against Zhengmei.

The Killer Queen had initially avoided using her explosive ability, relying solely on combat techniques to conserve aura....

60 HxH: The Strongest Assassin

Zhengmei's eyes widened.

"What's going on?"

"Killian… exploded?!"

"Was that part of the assassin's ability?" he muttered, her gaze darting around. "Or… is someone else involved?"

His movements were sharp as he sprang to his feet, surveying the area with heightened vigilance.

By now, Killian had been obliterated—reduced to nothing more than powder. In the center of the battlefield, the ground was sunken, leaving a massive crater.

Kaizen approached Zhen...

59 HxH: The Strongest Assassin

In a secluded valley, Killian sat on a rock, his posture relaxed but his eyes sharp. Across from him stood two figures:

One was a tall, bald man—Keke, a powerful Enhancer. Beside him, a much smaller, thinner figure exuded a cold, menacing aura. It was Zhengmei, her sharp gaze scanning the surroundings like a hawk.

"Cole and Fransky are gone," Killian said flatly, as if stating the weather.

"It's highly likely they ran into trouble. I didn't expect that among the prisoners,...

58 HxH: The Strongest Assassin

The car exploded in a deafening roar, engulfed by a massive fireball.

Fransky wasn't fast enough.

The blast hurled the vehicle's wreckage across the street, and the driver perished instantly. The air reeked of burning metal and rubber as thick smoke billowed into the sky.

Fransky emerged from the debris, his body charred black and barely able to move. Every step was agonizing.

"Still alive?"

He staggered into an alley, dragging himself along the ground. With his ...

"This guy's got real talent in combat," someone muttered.

"And he doesn't even use aura—he still managed to pull off that contract, and it scared the prison officials stiff."

"The guy's a killer, no doubt."

"His assassination skills are sharp."

"And cold-blooded."

"If someone like him made it to Heavens Arena, took the rookie challenge… he'd become a serious contender. Probably outclass Isaiah with ease."

"Maybe even reach the level of a Phantom Troupe ...

56 HxH: The Strongest Assassin

When it comes to money, not even the Phantom Troupe can compare to the endless streams of gangsters in this world. But no amount of cash can buy the services of Maha Zoldyck so easily.

This is simple math.

The Zoldyck family has the ability to eliminate anyone—be it the Ten Dons or the Phantom Troupe. In the original events, the Ten Dons were wiped out.

As for the Phantom Troupe? Chrollo Lucilfer stands no chance against Silva and Zeno. And the rest of the Spiders together...

55 HxH: The Strongest Assassin

Death row prisoner No. 3.

Keke.

Among the five condemned prisoners, Keke was the oldest and had taken the least damage over the years. His only known skill was in combat, and nothing else about him stood out.

"There are two types of aura users," Kaizen muttered to himself.

"One type is like Netero—those whose lifespan has been extended far beyond the norm. They might look ancient, but their strength hasn't faded. In fact, it's even greater than when they were young."...

54 HxH: The Strongest Assassin

"Death row prisoners?"

Kaizen paused as he reviewed the task details.

The job targeted five individuals—all death row inmates who had escaped from maximum-security prisons. The client? The prison officials themselves. Kill or capture, either would suffice.

Each target was worth 100 million Jenny.

"The prison must have failed to hunt them down on their own, probably multiple times," Kaizen muttered. "No choice but to put bounties on the dark web."

If the reward ...

53 HxH: The Strongest Assassin

"By the way, Kaizen, how long are you planning to stay at Heavens Arena?"

"It might take a while," Kaizen replied. "I want to watch today's fight."

The Heavens Arena holds a grand tournament every two years.

The first stage pits the Floor Masters against one another. The champion among them then meets the former Battle Olympia champion in the final match..

After the battle between Carlisle and Juliana ended, Kaizen noticed that the crystal ball's absorption speed had s...

52 HxH: The Strongest Assassin

"It's done."

Kaizen gave his precise location over the phone, then hung up.

Afterward, he returned to the room.

Lina looked up at him. "Kaizen…"

Kaizen nodded but said nothing.

Seeing his silence, Lina curled up quietly in the corner, much like a frightened animal.

Evening.

Knock! Knock! Knock!

There was a sharp rapping at the door. Kaizen approached, peeking through the peephole.

"Condense!" he whispered, activating Gyo to confirm the v...

51 HxH: The Strongest Assassin

Kaizen's mind wandered back to a memory from his previous life.

He remembered reading a manga called Fullmetal Alchemist. One of the alchemists in the story had merged his daughter with a dog to keep his title as a State Alchemist. The man, who seemed gentle at first glance, had committed a monstrous act for his selfish ambition.

That haunting scene had stayed with Kaizen ever since.

And now, something eerily similar was unfolding before him.

Carlisle's new puppet wore...

50 HxH: The Strongest Assassin

The crowd was buzzing with excitement as the fight between Carlisle and Juliana reached its boiling point. Their battle had been intense from the very start, but Carlisle's power had undeniably grown.

BOOM!
BOOM!
BOOM!

A rapid exchange of blows echoed through the arena, each collision shaking the ring. Juliana gave a low grunt, visibly surprised by her opponent's strength.

"I didn't expect you to improve this much in just two weeks," she admitted, a hint of respect in ...

49 HxH: The Strongest Assassin

On one side of the arena stood Carlisle, Kaizen's acquaintance. On the other, the top fighters of the 200th floor of Heavens Arena.

One of them was Juliana.

Another was Biscuit Krueger, who was of the same caliber but on a different level in her own way. Though Juliana wasn't as strong as Biscuit, she was still among the best on the 200th floor. Her record boasted an 80% win rate—just two victories away from earning the right to challenge a Floor Master.

Carlisle hadn't be...

48 HxH: The Strongest Assassin

"You won't even see where my next attack comes from!"

Partridge smirked, preparing for his next move, confident in his strategy. Kaizen's expression, however, was calm—perhaps too calm, almost amused.

"Let me open the door for you... to a whole new world."

A thunderous collision echoed through the arena.

Boom!

But in the very next instant, Partridge's face froze in disbelief.

His invisible left leg—his trump card—had been stopped cold.

"What...?...

47 HxH: The Strongest Assassin

When Kaizen arrived on the 200th floor of Heavens Arena, the entire floor buzzed with excitement.

Many fighters didn't stay permanently on this level. Instead, they came and went, waiting for new challengers to arrive. And when a newcomer reached the 200th floor, the predatory fighters known as "rookie killers" were ready to pounce, hoping for an easy win.

Several of them had already submitted applications to fight Kaizen.

"I hope I get the match!"

"It's gotta be me!"<...

46 HxH: The Strongest Assassin

Not long after returning to his room, Kaizen heard a knock at the door.

He opened it to find Lina standing outside.

"Come on in," Kaizen said, letting her inside for a while.

Later that evening, Carlisle came by to collect Lina.

"Congratulations," Kaizen said.

"I just got lucky," Carlisle replied modestly.

"Let's go, Lina," Carlisle called.

"Okay, Father."

With Carlisle and Lina gone, silence settled back into the room. Kaizen's gaze shifted to ...

45 HxH: The Strongest Assassin

"Begin!"

Carlisle's aura surged as Isaiah braced himself. The referee's hand dropped, and the fight was on.

Kaizen leaned forward, watching the battle from the audience seats with narrowed eyes. Before him, a small crystal ball pulsed faintly, resonating with the aura in the arena. As the match intensified, the crystal's absorption seemed to quicken.

This is faster than usual, Kaizen noted. He had observed this phenomenon before. It was one of the reasons he decided to atten...

44 HxH: The Strongest Assassin

A young man smirked, his expression a blend of amusement and mockery as he addressed the old man in front of him.

"Do you really think your plan will work?"

"Time isn't on your side," the old man said calmly. "You don't have the luxury of patience. But we do."

Suddenly, the sharp sound of knocking interrupted them.

Knock. Knock. Knock.

Kaizen opened the door to find a familiar face on the other side.

"Hello!" chirped the little girl standing there, her eyes...

43 HxH: The Strongest Assassin

Kaizen hadn't been idle these past few days. He'd been collecting information about the fighters on the 200th floor of Heavens Arena. Among the names, one stood out: Isaiah.

Isaiah was an old man who had spent his life training in a dojo. Now, in his later years, he'd ascended to the 200th floor. His rise through the ranks was impressive, but something strange had happened after he hit a slump. Following two consecutive losses, his strength surged dramatically—enough to make even Kaiz...

42 HxH: The Strongest Assassin

From the 200th floor to the 250th floor, there are 51 floors in total.

The top levels—230th to 250th—aren't used for competitions. Instead, these are the private residences of 21 floor masters, with each floor belonging to a single master. Every floor master also receives a share of the profits from matches held on the 200+ floors. Tickets for these fights are expensive, but there are no cash prizes for the contestants. Still, it's a lucrative arrangement.

The 200th to 229th f...

41 HxH: The Strongest Assassin

"It's about time to end this."

Kaizen drove Erlang back with a powerful punch.

Despite the intensity of the fight, Kaizen held back. He found something admirable in Erlang, so he gave him a chance. If Kaizen had gone all out, the fight would've ended much sooner—but now it was time to wrap it up.

Just as Erlang stumbled back, Kaizen vanished.

When he reappeared, he was behind Erlang.

Thwack!

Kaizen's hand chop landed sharply on the back of Erlang's neck.<...

40 HxH: The Strongest Assassin

Zeno's expression twisted as he read the message.

"The commission was rejected?"

"Do you realize it's not Kaizen's match?" someone asked nearby.

Zeno shook his head slowly. It wasn't the withdrawal that troubled him. It was how hastily the mission had been accepted in the first place.

One of Zeno's strictest rules was this: if a target is beyond reach, it's always wiser to retreat. That's a core principle of the Zoldyck family—withdraw before defeat. But even more im...

39 HxH: The Strongest Assassin

Without leaving Heavens Arena, Kaizen noticed how quickly his essence absorption technique progressed.

"At this rate, it'll take almost two months."

"Twice as long as it took at the Zoldyck estate..."

He frowned. "But we'll hit the same wall—if we stay in one place for too long, the rate of aura absorption will slow down."

Changing locations was essential to avoid stagnation.

Kaizen looked up toward the upper floors. "Below the 200th floor, that won't be a prob...

38 HxH: The Strongest Assassin

Kaizen thought back to Klose earlier.

"Are you with Klose?"

"That's right!"

"Then you misunderstood something."

"What do you mean?"

The man in front of him frowned.

Kaizen's voice was calm, almost mocking. "He made me an offer—throw the fight and he'd give me three million Jenny."

The man's eyes narrowed, tension building between them.

"If your group was confident you'd win, why do you think Klose offered me that kind of money? Charity?" Kaize...

37 HxH: The Strongest Assassin

"I watched both of your fights," the man said, a glint of admiration in his eyes.

"I must say, you're a genius."

"People like you don't come around often in Heavens Arena."

"Those two matches already drew a lot of attention. You've become one of the rising stars here."

"Many fighters above the 100th floor aren't half as good as you."

He leaned in closer. "Work with me, and we'll make a fortune together. Enough wealth to live without worrying about food or rent."<...

36 HxH: The Strongest Assassin

"Of course!"

The Rift Maniac charged at Kaizen with wild abandon.

Kaizen didn't move.

Seeing this, the Rift Maniac lunged, aiming to strike—but Kaizen shook his head.

"You can't even see what's around me, and you still think you can kill me?" Kaizen said, his voice calm.

A memory stirred in Kaizen's mind: Kurapika at the Zoldyck estate. After leaving the manor, Kurapika had gone off on his own instead of heading to Heavens Arena. He was hunting information abou...

35 HxH: The Strongest Assassin

"It's a bit ridiculous."

"Bach isn't weak. He advanced to the 50th floor with an impressive win just recently."

"Honestly, his true strength exceeds the 50th floor."

"Who is that kid, anyway?"

"He's just a teenager."

"And yet Bach was defeated that easily…"

"Unbelievable."

"Pushing Bach like that with one palm—what kind of monster is he?"

After his victory, Kaizen made his way to the 70th floor of Heavens Arena to register for the next compe...

34 HxH: The Strongest Assassin

At that moment, a hand emerged from behind the masked man.

"Pfft!"

A slender needle pierced into the back of his neck.

"First bomb," whispered Kaizen.

A second later, the needle detonated.

There was no visible explosion, yet the masked man's brain had been turned to pulp. The blast was precise, leaving his skull intact—deliberately calibrated so that the destruction was internal. On the outside, his head remained untouched, but the damage was done.

"Kille...

33 HxH: The Strongest Assassin

Could such a young child really be a fighter at Heavens Arena—and already make it to the 50th floor?

Impossible.

Ridiculous!

"Hey, kid, aren't you coming out?"

Sadaso finally couldn't help but ask.

Kaizen gave him a dismissive wave.

Before Sadaso could respond, the elevator doors slid shut.

The elderly attendant by the elevator cast a scrutinizing glance at Kaizen. At first, he had assumed that Kaizen and Sadaso were together. But now, it was clearâ...
