Chapter 15 – Seals and Sage Power
The world beyond Konoha's walls was changing.
The Third Great Ninja War had begun. Borders burned, armies marched, and alliances shifted with the wind. But inside the village, life continued — and Yuva Hiwatari focused on the only thing that mattered: preparation.
He knew that every second counted. And now, with the Shadow Clone Jutsu, he could make every second worth far more.

🌀 The Shadow Clone Advantage
Yuva's greatest weapon wasn't a blade or a jutsu.
It was his mind — and now, his ability to multiply it.
Each morning, he created 20 shadow clones and sent them to different parts of the training field. Each had a specific purpose:
5 clones focused on elemental ninjutsu refinement.
5 clones practiced weapon enhancement and chakra flow techniques.
5 clones studied and practiced sealing arts.
5 clones meditated and experimented with nature energy.
And when they dispelled, every memory, every mistake, every success flowed back into Yuva's mind. What would have taken him a month now took a single week.
This is the power of the Shadow Clone technique, he thought. It's more than just numbers — it's time itself.

📜 Sealing Arts – The Foundation of a Shinobi
One of Yuva's biggest focuses was fūinjutsu — sealing techniques. In a world as dangerous as the ninja world, seals could change everything. And now, he would master them.
💥 Explosion Seals
The first step was learning explosive tags — basic but deadly tools. Under the guidance of old scrolls in his father's library, Yuva and his clones practiced inscribing chakra formulas onto paper.
The hardest part was precision. One mistake and the seal wouldn't trigger — or worse, it could detonate in his hands. But within two weeks, Yuva could make reliable explosive seals strong enough to blast through thick stone walls.
He then experimented by attaching them to kunai and shuriken — creating deadly projectiles that detonated on contact.
These will be invaluable in the war, he thought. A hidden seal is more dangerous than a blade.

📦 Storage Seals and Scrolls
Next came storage seals, the backbone of every shinobi's utility arsenal. These seals compressed physical objects into scrolls, allowing him to carry weapons, supplies, or even water for suiton jutsu in battle.
Yuva practiced sealing and unsealing kunai, shuriken, and even small crates of tools.
Then he advanced to more complex work — creating custom scrolls that held dozens of tagged weapons ready to be summoned mid-fight.
It wasn't glamorous work, but it was powerful. One day in war, this could save my life.

🌿 The Path of Natural Energy
While half of his clones focused on sealing, the other half explored the most dangerous — and most rewarding — part of his power: natural energy.
Yuva knew he was far from mastering it. Too much, and he risked turning to stone. Too little, and it wasn't worth using. But now, with his clones, he could experiment safely.
At first, he practiced sensing and drawing nature energy in microscopic amounts.
Clone #1 absorbed tiny traces and immediately dispelled if stone began forming.
Clone #2 combined natural energy with basic chakra molding.
Clone #3 tested nature energy mixed into lightning chakra.
Clone #4 infused nature energy into water chakra.
Clone #5 tried to stabilize nature energy while forming seals.
Each attempt ended differently — some failed, some exploded, and some caused the clones to petrify and vanish instantly. But every memory returned to Yuva, teaching him what worked and what didn't.
And slowly… he began to improve.

⚡ Nature-Enhanced Jutsu – The First Steps
Two weeks later, Yuva tried something new: mixing traces of nature energy into his regular jutsu.
His Lightning Ball Jutsu became sharper and faster.
His Thunderbolt Strike crackled with deeper, darker lightning — a faint trace of purple hidden in its core.
His Water Bullet struck with more force, hitting like a solid projectile instead of a liquid blast.
It was still unstable — he had to monitor his body constantly to stop stone from forming — but it was a breakthrough. For the first time, he wasn't just wielding chakra. He was wielding the raw power of the world itself.
"This is just the beginning…" Yuva whispered one night as his hand glowed faintly with sage lightning. "When I master this completely… no one will be able to stop me."

🌀 Shadow Clone Multiplication – The Ultimate Training Method
By now, Yuva had completely restructured his training routine:
Daytime: Team missions, teamwork drills, and jutsu refinement with Tenzo and Daichi.
Evening: Sealing practice with clones and field testing new explosive tags and storage scrolls.
Night: Deep meditation and nature energy experiments — often with 10 or more clones at once.
The results were terrifying.
Yuva could now create 20 stable shadow clones without strain.
He could inscribe explosive and storage seals faster than many chūnin-level seal masters.
He could mix tiny amounts of nature energy into elemental jutsu without losing control.
His elemental attacks were sharper, faster, and stronger than ever before.

🪶 The Triplets' Progress
While Yuva was diving into seals and sage energy, his brothers weren't idle either.
Tenzo refined his wind techniques with shadow clones, focusing on precision and speed.
Daichi improved his earth and fire combinations, using clones to simulate battlefield conditions.
Both learned Shadow Clone Jutsu and used 6–7 clones each to train double-time.
The three of them grew at a pace that even Hari found unsettling.
"They're not just children anymore," he murmured one evening, watching their chakra signatures flare across the training ground. "They're becoming monsters."

🌩️ Preparation for the Future
As summer deepened and the war outside the village escalated, the Hiwatari triplets stood on the edge of a new stage in their lives. They weren't just academy graduates anymore — they were on the path to becoming weapons forged by fire and battle.
Yuva looked down at his hands, faint sparks of purple lightning dancing between his fingers. "I'm still far from mastering this," he whispered. "But when I do… no one will call me weak."
The storm of war was coming.
And when it reached Konoha, the Hiwatari triplets would not hide from it.
They would meet it head-on.
