The hallway of the Vongola main estate was quiet—eerily so, as if even the walls knew something grand was about to begin.
Small footsteps echoed against marble. The sound did not belong to a child, despite appearances.
Dressed in a suit tailored to perfection, with a fedora resting neatly on his head, a lizard calmly perched on its brim, the infamous hitman known across the underworld strolled with quiet ease.
He carried an exquisite box.
And as always, he wore a sharp gaze—calm, unreadable, and cold enough to send grown men to their knees.
Yet oddly enough, he was missing one thing.
The pacifier.
"Leon," Reborn muttered, adjusting the weight of the box in his arms. The chameleon flicked its tail, but said nothing. It didn't need to.
The pair stopped before a large door, carved with symbols of the seven flames. With a soft push, Reborn entered.
"Ciao-su."
The girl inside smiled at the familiar greeting.
Seated near the open balcony, Yuni, the Sky of this generation's Arcobaleno, glanced back.
The soft wind caught her hair, the sun painting her silhouette in a serene glow. Even without her pacifier, she radiated the calm of one who bore the Sky flame.
"Uncle Reborn," she greeted warmly, her voice as light as air, "you're early."
"Mm," Reborn nodded, stepping forward and placing the box on the table. "You're not nervous?"
Yuni tilted her head. "For the memorial?"
He gave her a pointed stare.
It was a special day. A solemn remembrance of the Arcobaleno system, and the ceremonial affirmation of Yuni's place as the Sky—no longer bound by the curse, but bearing its legacy and the ceremonial of the Vongola's Tenth Boss.
Yuni shook her head softly. "I'm not."
Then, after a pause, her lips curved upward.
"But someone else was."
Reborn raised a brow.
She chuckled lightly, like a breeze through old paper. "There's a brown-haired boy who couldn't stop trembling a few minutes ago. He was so nervous I thought the floor would start shaking with him."
A sigh escaped Reborn's lips, long and helpless.
"…Dame-Tsuna."
The name rolled off his tongue like an old habit—half scolding, half affectionate.
The silence that followed was warm. Not heavy.
His mind drifted, involuntarily, to the past.
From the timid boy who couldn't speak a full sentence without stuttering…
To the young man who now stood at the center of the most powerful Mafia families in the world.
Sawada Tsunayoshi.The Tenth Vongola Boss.
At seventeen, he was already being called "Decimo" with both reverence and fear.
The old throne now had a new occupant although it is given by the one who had never wanted it, yet had grown into its weight like a flame accepting its form.
Reborn's lips twitched.
Their journey had been long.
Violent. Chaotic. Beautiful.
Reborn allowed himself a rare pause. He stared out the window as memories flickered by memories of the fights won, friends lost, the laugh of boys who had become brothers.
But the tranquility shattered like glass.
"UWAAAAAH! IPIN STOLE MY CAKE AGAIN!!!"
A thunderous crash followed as the door burst open. Lambo stormed in, face tear-streaked, trailed by a nervous Ipin.
Lambo and Ipin.
Reborn's eye twitched.
Before Yuni could even raise her hand to speak, Lambo found himself flying—unceremoniously launched through the balcony window.
"OUT."
A familiar scream faded into the sky.
Yuni sighed, watching the clouds with a helpless gaze.
"…Uncle," she began gently.
But a knock interrupted her.
A Mafioso in clean formalwear stood at the door.
"It is time. The ceremony shall begin."
Reborn adjusted his fedora.
"…Hmph. About time."
Outside the grand hall, the ceremony had begun to stir.
The courtyard was filled with esteemed guests from across the Mafia world.
Murmurs spread like wind over calm water, all eyes subtly shifting to the boy who would inherit the Sky.
The one once deemed hopeless. Now, standing on the brink of history.
At the center of it all, Sawada Tsunayoshi stood quietly, flanked by the unwavering presence of his Guardians.
"Hold it together, Juudaime," Gokudera whispered fiercely at Tsuna's side, eyes scanning the growing crowd with caution—and devotion.
His hand gripped his jacket tightly, hiding the tremor of emotion that threatened to spill from his chest.
Chrome gently approached with a calm smile. "It's alright, Boss," she said softly, "you've carried us all this way."
A few steps back, Yamamoto chuckled lightheartedly, watching Tsuna's nervous expression. "Haha, man, this is more intense than nationals. But hey… we've got your back."
"DON'T SWEAT IT, TSUNA!" Ryohei bellowed, his fists clenched as though he were about to throw a punch at the very air. "CELEBRATE THIS TO THE EXTREME!!"
Tsuna laughed nervously, but his expression betrayed how overwhelmed he truly felt.
More and more guests began to arrive—familiar faces, old allies, and former enemies.
The Shimon Family, ever composed, approached first. Enma gave a polite bow, offering warm congratulations. "You've grown, Tsuna. We're honored to witness this."
Tsuna bowed in return, grateful for the familiar warmth.
But peace is never without its shadows.
In the back, standing with arms crossed and an unmistakable scowl on his face, was Xanxus. The Varia boss said nothing, but the disdain in his eyes was louder than words. Squalo grumbled beside him, though even he didn't dare to make a scene.
Tsuna gave a stiff, awkward smile.
'Not everyone was happy with the choice.'
Suddenly, the sharp sound of a ceremonial horn echoed through the air.
The noise stilled every voice, every breath.
The time had come.
One by one, guests took their seats, forming a grand ring around the main platform.
Tsuna ascended the central stairs—each step heavier than the last.
His Guardians followed and took their designated seats just below the main stage, facing outward like the celestial bodies around the Sky.
Gokudera could barely sit still, trembling as tears pricked his eyes. "Juudaime… you did it," he whispered to himself, voice shaking.
Yamamoto patted his shoulder with a helpless grin before sitting, his calm and confident aura grounding the atmosphere.
Chrome folded her hands and smiled peacefully.
Lambo sat down, laughing loudly for no reason at all, unaware of the emotional weight around him.
Ryohei's eyes gleamed like fire. Passion burned off him like heat from the sun.
And then, there was Hibari.
He said nothing, arms crossed and expression unreadable. But a small, imperceptible smile curled at the edge of his lips—quickly hidden by the shadow of his bangs.
Moments later, Yuni emerged, holding in her hands a silver tray that cradled seven gleaming pacifiers, each one glowing faintly with the essence of its original bearer.
Behind her walked the Arcobaleno—still in infant form, but unbound by the curse that once shackled their souls. Though small in stature, their presence filled the room with weight and legend.
And at the center of them, Reborn stepped forward with a box—exquisite and ancient. In his gloved hands, he presented the six Vongola Guardian Rings, each resting in velvet cradles, glimmering like stars that had waited long for this moment.
He placed the box before Tsuna, and beside it, a red pillow embroidered in gold thread held the Sky Ring—the flame that would unite them all.
Reborn turned, bowed to Yuni, and walked away to sit with the Arcobaleno.
Yuni remained at Tsuna's side.
Each Arcobaleno took their seat besides their designated guardian whom they once embodied.
The room glowed in quiet reverence.
Then came the final piece.
A man in a black coat, old and wise, with a smile as warm as a fading sunset—Vongola Nono, the Ninth Boss—stepped onto the stage.
He looked at Tsuna with eyes full of pride.
"When I chose you, many doubted. I, too, was unsure. You were scared. Clumsy. Powerless."
"And yet…" he paused, voice trembling, "…you never turned your back on what mattered."
Nono raised a hand.
"Today, I ask you… Sawada Tsunayoshi. Come forth. Accept your rightful place. Become the Sky of the Tenth Generation."
Tsuna stood, heart thudding like thunder in his chest. He walked to the front of the platform.
Everyone stood.
The hall was filled with applause.
As Tsuna bowed deeply, the words echoed like thunder from all sides:
"All hail, Vongola Decimo!"
He reached for the ring—
The instant the ring touched his fingers,
Tsuna felt it.
An unsettling ripple in the air.
Like the breath before a storm.
The ceremonial hall, which was filled with symphony of applause and celebration a moment ago, was now shrouded in eerie silence.
The chandeliers flickered, the scent of incense barely masking the growing tension.
Then—
smoke bomb exploded near the east balcony. Within seconds, two gunshots pierced the thick fog.
Bang! Bang!
The first struck Yuni, blood blooming from her abdomen like a red flower on white silk. Her expression froze, serene—almost confused—as her knees buckled.
The second bullet flew toward her heart.
Yet, without a thought, Tsuna moved on instinct.
"Yuni—!!"
The Sky Flame erupted around him like a blazing star, but not fast enough—
The bullet dug deep into his right shoulder.
"JUUDAIME!"
The Guardians surged forward, weapons raised—Gokudera's hands already glowing with dynamite, Chrome stepping into illusion, Ryohei roaring his battle cry.
But before they could reach him—
Tsuna's body froze.
His eyes—clear, golden—locked onto something beyond the smoke. His Sky Flame pulsed wildly.
"STOP!!" he bellowed.
All six Guardians stopped dead in their tracks.
Tsuna flared his wings of fire and took to the skies—Yuni in his arms, clutching the Six Guardian Rings and the Arcobaleno Pacifiers tightly to her chest.
From above—
A sudden torrent of bullets rained down.
A helicopter, previously hidden by cloud veils, hovered at close range, its gunners firing relentlessly at point-blank range.
Below, chaos broke out.
"YUNI-SAMA!" someone screamed.
"JUUDAIME!!" Gokudera's voice cracked with panic.
Ryohei shouted to protect the injured with burning fervor, while Yamamoto's sword was already unsheathed.
But Tsuna's voice, weak yet commanding, stopped them.
" Something's wrong..."
He could feel it—Not just danger, but something alien.
Not from this time.Not from this world.
Above, the sharp metallic grind of machinery whirred. A helicopter emerged from behind the high marble columns of the ceremony hall—unmarked, untraceable.
And then—
The world turned red.
Bullets rained like divine punishment,
unrelenting and indiscriminate. Not aimed at intimidation.
No.
This was an execution.
A massacre.
The flames around Tsuna expanded violently. What once flickered like a candle now roared like a sun.
The Hyper Dying Will Mode responded to his pain, to his resolve—to his unwillingness to lose anyone.
He created a flaming sphere, a dome of living fire that shielded him and Yuni midair.
The bullets burned against the power of the Sky flame—yet the force behind them felt… wrong.
Every shot carried a weight, a coldness—technology far beyond their age.
Tsuna's mind spun as he pushed the flames harder, blood pouring from his shoulder.
Yuni, coughing lightly, clinging to the seven Arcobaleno pacifiers and the six Guardian Rings. She felt their heat—so close to Tsuna's heart. So fragile now.
Below, Reborn's expression twisted. The smoke choking the air wasn't normal. As his instincts screamed.
"This pressure… this is…"
His eyes widened.
"…Like ten years in the future."
The Arcobaleno faltered. Their limbs grew heavy. Even Skull's cries fell silent.
As darkness clouded their vision, Reborn—still fighting the weight on his chest—managed to whisper:
"Tsuna… Run."
Then, silence.
Something in the smoke—a chemical? An energy pulse? Their souls were being suppressed.
Up above, Tsuna gritted his teeth, holding on as flame and metal clashed in the skies.
He opened his palm, and with a cry that tore the heavens—
"X-BURNER!!"
Two beams of flame, pure and unyielding, fired down.
The helicopter disintegrated, swallowed by the blaze.
Embers rained down like fireflies.
The crowd below, emerging from smoke and ruin, cheered.
"He did it!"
"Boss Tsuna!"
"The Decimo!!"
But as the flames faded—
Silence took their place.
Tsuna hovered in the sky, clutching Yuni.
And blood was pouring from his side.
Dozens of wounds.
Crimson soaking his ceremonial suit.
Eyes half-lidded, pale lips forming faint words.
"Tsuna…?" Chrome gasped.
"This—this is impossible!" Gokudera shouted. "His Flames should've destroyed the bullets!"
Spanner knelt beside a discarded bullet.
His face turned pale.
"This isn't… from here," he muttered. "This material… it's not of this time."
Yamamoto's smile had faded.
Even Ryohei, eyes burning with determination, stood still.
Chrome wept silently, clutching her trident.
Above, Tsuna swayed.
He only looked upon at Yuni, her face was pale but she had a faint smile.
"You okay?" he whispered.
She nodded weakly, her vision blurred with tears.
"I should ask you the same…"
She reached for his cheek—
But her hand froze.
Blood.
Dripping from the corner of his lips.
He smiled gently, eyes unfocused.
"I'm fine…"
But he was falling.
His wings flickered, his knees gave way but steadied himself right afterwards.
From below, the Guardians screamed.
"JUUDAIME!"
"TSUNA!!"
"BRO—!!"
He chuckled.
"Guess I overdid it…"
Yuni's lips trembled. "Why… why are you smiling…?"
Tsuna's voice was soft.
"Because… I'm glad you're safe."
He looked below—at his Guardians.
His friends.
His family.
The Arcobaleno remained motionless, their bodies asleep under strange suppression.
But Reborn's eyes fluttered open one last time.
He saw the boy he raised—the boy who called him "home"—bleeding, slowly fading into the clouds.
And then—
"…Sorry."
The words fell like cherry blossoms—quiet and beautiful.
Soft. Almost inaudible.
Yet, the word echoed and every Guardian heard it.
Their eyes widened.
Tears spilled without permission.
Hearts cracked.
The last of his flames flickered.
And the Sky—
Fell.
He dropped like a shooting star, cradling
Yuni.
Into the sea.
The wind howled.
The waves churned.
"TSUNAAAA!!" they all cried.
The sea answered with silence.
A bright coronation turned into a catastrophe.
A boy who only wished for peace, dragged back into the flames.
Now swallowed by the ocean—
Where destiny slumbers.
Above, stars dimmed.
And the sky…
was silent.
