"Moonwalk."
Poof!
Tsuna pressed down with one foot, and without relying on flames, his body shot upward mid-air.
In his "Hyper Dying Will Mode," Tsuna's physical strength had increased to an inhuman level.
After one successful move, he stepped forward again.
Each time he kicked, a ring of compressed air rippled out, allowing him to remain suspended in the sky.
Seeing this, Ken and Chikusa were left utterly stunned.
You see...
The "Six Styles" of the Navy was something that Mukuro had painstakingly taught Ken and Chikusa, after investing a third of his wealth into the training.
Yet Tsuna—after just observing Ken perform it a few times—had managed to master this otherworldly technique!?
At this moment, a troubling thought occurred to Mukuro.
Could Ace have intended for Tsuna to learn the Navy's Six Styles from them?
In truth, Mukuro was blaming Ace unfairly.
Even though Ace did have his reasons for trading with Mukuro, he hadn't planned on such an outcome.
Meanwhile...
Ace, who was watching from a hidden vantage point in a tall building, was just as shocked when he saw how easily Tsuna had grasped the technique of "Moonwalk."
When Ace had recommended the Navy's Six Styles to Mukuro and his people, he never expected anything like this to happen.
Although Tsuna had been training in the Six Styles for half a month, under Ace's direction, he was the slowest learner with the least aptitude of all the trainees!
There was no way Ace expected someone like Tsuna—who couldn't even perform a basic training move—to learn the Navy's Six Styles.
And yet, what was unfolding before him...
...was the undeniable truth.
"It seems I've underestimated the powers of this world," Ace muttered under his breath, a flicker of white light crossing his eyes.
The power system in the Hitman Reborn world could indeed enhance both understanding and talent.
Now, Ace's interest in the powers of this world was piqued.
"I wonder... is this ability unique to Tsuna, or is it something universal?"
Ace spoke quietly to himself, but his gaze remained locked on the center of the battlefield.
Due to Tsuna's sudden mastery of the Moonwalk, the main battle had shifted to the skies.
Ken kicked off the air, rushing towards Tsuna with all his might.
However...
Due to his own physical limitations, Ken couldn't keep up with Tsuna in the air.
After all, one must not forget...
Tsuna's flames also granted him the ability to fly!
But fortunately, Mukuro and Murkrow had mastered their own game-changing powers!
Crack!
A black bolt of lightning suddenly flashed past Tsuna's side.
Having predicted Murkrow's attack route, Tsuna quickly raised his hand.
In the next instant...
Murkrow's wings collided with the Vongola gauntlet, unleashing an incredible force that spiraled outwards like a hurricane.
In terms of raw power, Tsuna in his Hyper Dying Will Mode seemed evenly matched with Murkrow.
However...
Tsuna not only possessed overwhelming physical strength, but also wielded the mighty power of the Sky Dying Will Flame!
Suddenly, Vongola's gauntlet ignited, and fierce flames raced along Murkrow's wings towards its body!
"Huh?!"
The soul of Mukuro, controlling Murkrow, instantly reacted and pulled back. Even though he couldn't feel the pain of being burned, he didn't want Murkrow to suffer unnecessary damage.
At this point, Mukuro had to admit that his initial judgment had been completely wrong.
Who could have imagined that a weak and useless Vongola Decimo could transform into such a fearsome warrior?
This kind of power was enough to carve out a significant position, even in the mafia underworld.
In the original timeline, Mukuro was easily defeated by Tsuna in his Hyper Dying Will Mode.
Let alone Tsuna, who had undergone half a month of rigorous naval training.
At this point, based on Leo's power scale, Tsuna's strength was roughly at level 19, though still under level 20.
Stronger than both Murkrow and Mukuro.
However...
Due to the protagonist's "halo," the full extent of Tsuna's power remained uncertain.
Super-intuition and learning abilities, after all, weren't factored into strength levels.
If not for the power Ace had traded to Mukuro, they would have surrendered the moment Tsuna entered his Hyper Dying Will Mode.
And now...
Mukuro had only one last card left to play.
——
On the battlefield, Tsuna boosted his momentum with flames, dodging Murkrow's assault at lightning speed. He then thrust his hands forward, unleashing violent flames before swiftly returning to the ground.
Taking advantage of the brief moment before Murkrow and Ken could react, Tsuna stamped the ground dozens of times in the span of a second, then whispered:
"Shave."
Whoosh!
A blazing figure shot out like an arrow, heading straight for Chikusa.
"Not good!!!"
Mukuro, sensing the danger through Chikusa's enhanced awareness, shouted inwardly.
But Chikusa's body was too weak. Even though he realized what was coming, his body couldn't keep up with Tsuna's incredible speed.
"One down."
Tsuna appeared before Chikusa and brought down his hand blade at his neck.
When it came to allies, Tsuna would always show mercy. But when dealing with enemies, he fought with relentless resolve.
Thud.
Chikusa, whose combat capabilities had plummeted, fell unconscious without resistance.
His head slumped as he crumpled to the ground.
Tsuna's gaze then shifted back to Ken, who was just beginning to descend from the sky.
He did not hesitate.
Continuous Footsteps + Flame Boost
Tsuna once again appeared beside Ken, facing him as an unstoppable foe.
Mukuro, having already tasted defeat, wasn't about to let that happen again so easily.
Suddenly, a pitch black armor enveloped the neck of Ken. Ready to flee at any moment, Ken prepared himself for an escape.
However…
Tsuna, anticipating this, showed no signs of knocking Ken out after getting close.
He simply raised his hands, igniting Vongola's gloves with blazing red flames.
Without hesitation, Tsuna swung his flame-covered fist and landed a powerful punch straight to Ken's face, sending him flying dozens of meters! The high temperature of the flames even scorched half of Ken's face.
"Next, it's your turn."
After forcing Ken to retreat, Tsuna suddenly leaped into the air, skillfully dodging Murkrow's eerie light.
He had always been extra cautious of Murkrow's attacks. With his super-intuitive foresight, Tsuna knew that if he were hit by that strange ray, the consequences would be dire.
Whoosh!
Fierce flames roared across the battlefield as Tsuna soared higher into the sky. Seizing the moment when Murkrow had just unleashed its attack, he circled around it swiftly.
While Tsuna couldn't knock out Murkrow—unsure of where its nerve center was—he had already gleaned some valuable insights from their brief skirmishes.
It was clear now…
Mukuro deeply valued the powerful Murkrow and didn't want it harmed.
In his "Hyper Dying Will Mode," Tsuna's fighting abilities and battle awareness had been pushed to the absolute peak of the world's standards!
What the enemy cherishes most is what he targets!
With a sharp motion, Tsuna raised his arm, flames scorching the earth beneath him, leaving a trail of charred black behind.
Then, he charged directly toward Murkrow!
"Not good!"
Mukuro's soul cried out in alarm.
Seeing the incoming high-temperature flames, Mukuro could no longer remain calm in his possessed state. The "Eye of Six Paths" in Murkrow's gaze suddenly vanished, returning the bird to normal.
But just as Murkrow regained control, it was met with the sight of flames racing towards it!
"Caw! Caw!!!"
The panicked Murkrow shrieked and flapped its wings frantically, unsure of which direction to fly in to avoid the attack.
In that chaotic moment, a voice suddenly rang out from somewhere on the ground:
"Hell Realm - Glacier World!!!"
Bang!!!
As the voice echoed, the ground in front of Murkrow split open, and a massive glacier erupted from the earth, rising to block the oncoming flames.
Boom!!!
The moment the scorching flames collided with the glacier, a thick cloud of white steam burst into the air.
Then, an explosion followed.
The flames shattered the glacier into pieces, and it dissipated into a cloud of smoke, vanishing from the battlefield.
Taking this opportunity, Murkrow swiftly retreated and landed on the shoulder of a figure.
This figure, of course, was none other than Murkrow's trainer—Mukuro.
"Caw!"
As soon as it landed, Murkrow let out an indignant squawk, clearly complaining about being placed in such a dangerous situation.
Mukuro responded with an apologetic smile and said, "I'm truly sorry. It seems the enemy's strength far surpasses my expectations."
He added, "From here on out, we'll have to fight the enemy together."
"Caw~"
Murkrow's expression softened after hearing the apology. It nodded and quickly turned its gaze back to Tsuna.
The earlier exchange had made it clear—Tsuna was not an opponent to be taken lightly.
Mukuro waved his hand, transforming his weapon back into a trident.
The numbers in his Eye of Six Paths shifted rapidly as he addressed Tsuna:
"I didn't want to use this power..."
"But I must admit, Vongola Decimo, your strength has exceeded my expectations."
"To defeat you and claim your body, I have no choice but to use it again…"
"This disgusting power!!!"
Boom!
A dark aura surged from Mukuro's body, and the number in his Eye of Six Paths changed to [Five].
Six Paths of Reincarnation - Human Path.
Although the power Mukuro had accumulated in the Human World had diminished significantly after his battle with Ace, the lingering power of malevolent thoughts remained overwhelming.
Even standing beside him, Murkrow could feel the corrupt energy swirling around Mukuro's body, causing a look of twisted satisfaction to spread across the bird's face.
To Murkrow, inherently aligned with evil…
The power of malevolent thoughts was the most exquisite feast in the world!
"Oh?"
On the other side, Tsuna's face remained composed as he witnessed the dark power erupting from Mukuro.
He even mocked, "So, the warm-up is finally over?"
"..."
"Why, you little brat," Mukuro spat angrily, immediately charging at Tsuna with Murkrow in tow.
The battlefield erupted once more into a storm of fierce combat.
Murkrow, under Mukuro's control, began employing various tactics: casting black mist to obscure the enemy's vision, unleashing fear-inducing abilities to rattle their resolve…
Compared to Mukuro, who relied mainly on brute force, Murkrow clearly preferred a more supportive role.
But it was a shame...
Against any other opponent, Murkrow's combination of moves would have been devastating.
Yet, Tsuna, in his Hyper Dying Will Mode, possessed an unshakable calmness and unparalleled combat prowess.
In the end, all of Murkrow's efforts came to nothing, yielding only minimal results.
What made Mukuro even more hopeless was that the dying will flame released by Vongola's gauntlets weren't just extremely hot and brimming with energy. They also had the power of the sun, able to purify darkness itself.
Finally…
After Tsuna risked everything and took a direct physical wing attack from Murkrow, he used his flames to completely cleanse Mukuro's power—until he passed out.
On the battlefield, only Tsuna and Murkrow remained, locked in a tense standoff.
Just as Tsuna prepared to return to his usual strategy—trading blows and injuries to defeat Murkrow—a sudden, sharp round of applause echoed from not far away.
Clap… Clap… Clap…
The unexpected applause immediately drew Tsuna's attention.
He turned to see where it was coming from.
A hint of surprise appeared on his otherwise calm face.
Clap, clap...
Ace stepped forward, walking over to stand next to Reborn, a cheerful smile spread across his face.
Ace grinned and said, "That's truly impressive, Tsuna. I never thought I'd be this surprised by someone else's skills."
"Ace… Ace-sensei…?"
Seeing Ace approach, the Dying Will Flame above Tsuna's head suddenly weakened, dimming by more than half before gradually extinguishing.
Although today's battle seemed to be closely linked to Ace's presence, with his extraordinary intuition, Tsuna could sense that the danger had now passed.
With no imminent threat, he voluntarily ended his Hyper Dying Will Mode, revealing his usual self and asked, concerned:
"What's going on, Ace-sensei?"
Ace smiled gently, a thoughtful glint in his eyes.
He figured it was time to stop keeping secrets and decided not to hide the truth any longer—especially since Tsuna needed to continue improving.
Without further delay, Ace began explaining everything.
Travelers from another world, the Transdimensional Chamber of Commerce, the power of Pokémon, the Navy's Six Styles, and even the [Whetstone] Mukuro Rokudo.
As these strange revelations spilled from Ace's lips one by one, Tsuna's expression shifted from initial shock, to acceptance, and finally, to complete numbness.
By the time Ace finished speaking, Tsuna could only force a faint chuckle, muttering through gritted teeth:
"Haha…"
