Chapter 10 – The Blade and the Stone
A month passed since the Hiwatari triplets received their new weapons, and their training only grew more intense.
With every day, their chakra control sharpened, their bodies strengthened, and their techniques refined. And now, with weapons forged for them alone, they were stepping into a level of power few academy students could even dream of.

⚔️ Tenzo's Samurai Training
Tenzo devoted himself entirely to mastering chakra flow into his new wind-aspected blade. He studied the samurai sword manual Hari had brought from the Land of Iron, memorizing every movement, every breath, every principle.
His first challenge was simple: cut a single falling leaf.
It took him three days.
Then it was two leaves together. Then three. Then five.
Weeks passed. His precision sharpened. His speed increased.
By the end of the second month, Tenzo was slicing eight falling leaves at once, each cut cleaner than the last. Then he raised the difficulty further — switching to senbon needles falling from above, cutting them before they touched the ground.
Soon, even senbon coated with wind chakra split in half midair.
Finally, he began leaf cutting exercises with his sword itself, sharpening the blade's chakra edge to slice leaves cleanly without physical contact. Slowly but surely, Tenzo was transforming into something rare: a swordsman whose blade moved with the wind itself.

⚡ Lightning and Senbon – Yuva's Training
Yuva too pushed his limits. He began practicing Lightning Senbon Technique, infusing tiny needles with his lightning chakra and throwing them with pinpoint precision.
At first, his control wavered — the senbon overloaded or discharged too soon. But within weeks, he could throw volleys of lightning senbon that burned through tree trunks and targets alike.
But even that wasn't enough.

⚡ The First Attempt – Nature Energy in the Sword
One evening, Yuva stood alone beneath the fading orange sky, holding his lightning-aspected sword in his hands. His breathing was steady. His eyes were calm.
It's time to try it, he thought. Time to bring nature energy into the blade.
Slowly — very slowly — he guided the sealed natural energy within him into his sword. His chakra flowed easily, wrapping the blade in crackling lightning. And then, for the first time, a faint purple glow — the mark of sage lightning — began to crawl across the steel.
The air buzzed around him. The ground vibrated. Yuva swung the sword.
BOOM!
A purple lightning slash exploded from the blade, tearing through five trees in a single swing.
He stared at the destruction in awe. But greed, the deadliest enemy of a shinobi, whispered in his ear.
More. Just a little more.
He pushed harder, drawing more nature energy into the sword. The purple glow brightened — and then his vision blurred. His body felt heavy. His skin… cold.
No… not again…
The stone transformation began to creep over his arm. He tried to stop the flow, but he had already lost control. The blade screamed under the pressure — and with a sharp crack — it shattered.
The sound echoed through the training field.
Yuva froze, staring at the fragments in silence. His breath caught in his throat. A million ryo — gone. A blade worth A-rank mission rewards — destroyed in seconds.
For the first time since his rebirth into this world, Yuva cried. Silent tears slid down his face as guilt and regret tore through him.
What will I tell Father? How could I break something like this…?
The stone creeping up his arm worsened, his body stiffening as he fell to his knees. His vision dimmed.
And then — everything changed.

🌌 The Sword's Rebirth
Inside his inner world, the mist stirred.
The vast sea of nature energy rippled and shifted as if responding to his despair. And before Yuva's eyes, the broken sword appeared before him, floating weightlessly.
Slowly, the swirling natural energy wrapped around the blade's shattered pieces.
Piece by piece, they reassembled themselves, the cracks sealing, the edge reforging. The metal darkened slightly, the faint purple glow pulsing stronger than before.
When the light faded, the sword floated before him — whole again.
The same shape. The same size. But different. Denser. Sharper. Stronger.
The inner figure — his nature energy self — opened its eyes briefly, then closed them again. The meaning was clear: You are not ready yet… but you are closer.
Yuva opened his eyes in the real world. The sword lay beside him — perfectly intact.
Shaking, he picked it up and channeled chakra into it.
The flow was smooth as silk.
When he added purple sage lightning, the glow surged — stronger, deeper, more condensed than before.
He swung — and the forest erupted.
A single slash of purple lightning cleaved through twenty trees, slicing them like paper.
But the price was steep. His vision swayed, his body trembled, and exhaustion crushed him. He fell to the ground, barely conscious, as darkness swallowed his senses.

👤 Tenzo's Witness
From behind a nearby tree, Tenzo had watched everything in silence. He had seen his brother cry for the first time, seen the sword shatter and then mysteriously repair itself. He had seen the surge of terrifying power in that final swing — a power that felt alive.
And he felt it too — the overwhelming, terrifying pulse of natural energy in the air. His instincts screamed that what Yuva had just done was beyond ordinary ninjutsu.
"Big brother…" he whispered, awe and fear in his voice. "You're… something else."
He rushed to Yuva's side as his brother collapsed and found that the creeping stone had already begun to recede. The transformation was stopping on its own.
"Hang on, I've got you," Tenzo muttered as he hoisted Yuva onto his back and ran toward the village.

🏥 Aftermath
At the hospital, the doctor examined Yuva carefully and sighed in relief. "He's fine," she said. "Just severe chakra exhaustion. He pushed his body too far in training. He'll recover with rest."
Tenzo nodded, relieved — but he didn't tell the doctor or their parents the whole truth. He didn't mention the broken sword, the terrifying purple lightning, or the stone creeping over Yuva's body.
Some things, he felt, were not meant for others to know — not yet.
As he watched his brother sleep, Tenzo clenched his fists.
Big brother… you're not just strong. You're something far beyond normal. And one day, the world will know it.
