Hinata and Ino returned after changing into their training clothes. Both looked refreshed and curious, wondering what Ren had prepared next.
Ren stood near the garden table, holding two small white sheets of special paper.
"Alright," he said calmly. "Channel your chakra through this paper."
Ino blinked in surprise.
"Wait… is that Chakra Affinity Paper?"
Ren nodded with a small smile.
"Exactly."
---
Hinata took the paper first and gently pushed chakra into it. The sheet reacted almost instantly.
One side of the paper burned slightly while the other side crumpled inward.
Ren nodded immediately.
"Lightning and Fire."
Hinata looked down at the paper in mild surprise.
"So I have two affinities…"
Her eyes widened slightly before she smiled softly.
"I… I didn't know that."
Ino leaned closer to examine it.
"Lightning and Fire? That sounds cool!"
Hinata rubbed the back of her neck shyly.
"I hope I can learn them properly."
Ren nodded confidently.
"You will."
---
Now it was Ino's turn.
She pushed chakra into the paper with a curious expression.
The result was dramatic.
The sheet turned partly into dust, split cleanly in half, and became slightly damp.
Ren raised an eyebrow before grinning.
"Earth, Wind, and Water."
Ino froze.
"THREE?!"
She stared at the ruined paper in disbelief.
"Are you serious?!"
Hinata looked surprised too.
"Ino… that's amazing."
Ino placed her hands on her hips proudly.
"Hah! Of course it is!"
Then she turned toward Ren suspiciously.
"Wait… does that mean I'm a genius?"
Ren shrugged with a smirk.
"You always thought you were."
"Hey!"
Hinata giggled quietly again.
---
Ren clapped his hands once.
"Alright, let's start training."
He turned to Hinata first.
"Hinata, focus on Lightning chakra first."
He picked up a leaf from the ground and held it between his fingers.
"Take a leaf and make it crumple using Lightning chakra."
Hinata blinked in confusion.
"But… how?"
"I don't know how to bring out Lightning chakra."
Ren nodded as if expecting that answer.
He picked up another leaf.
"Open your Byakugan and watch my chakra flow."
Hinata straightened slightly.
"Okay."
She activated her dojutsu immediately.
"BYAKUGAN!"
Her vision sharpened as Ren began channeling Lightning chakra into the leaf.
Tiny sparks of chakra vibrated through his fingers, causing the leaf to slowly wrinkle and crumple.
Hinata watched closely, analyzing the chakra movement.
Ren crumpled several leaves one after another.
"Did you understand?" he asked.
Hinata nodded slowly.
"I think so."
"Try copying it."
"Once you become familiar with the sensation, I'll place a seal that will help you train faster."
He added casually,
"You can also practice this when no one is watching."
Hinata nodded firmly.
"I will work hard."
Ren gave her a small warning.
"Just don't push yourself too hard."
"Yes, Ren."
---
Ren then turned toward Ino.
"So, do you want to train Wind first or Fire?"
Ino crossed her arms thoughtfully.
"Wind."
Ren nodded.
"Alright."
He tossed a leaf toward her.
"Take a leaf and cut it in half using Wind chakra."
Ino looked at him with a raised eyebrow.
"I don't have Byakugan, remember?"
"How am I supposed to copy you?"
Ren scratched the back of his head awkwardly.
"…Right."
Then he stepped closer and gently grabbed her hand.
Ino froze instantly.
"W-What are you doing?!"
Ren ignored the reaction and channeled Wind chakra through his hand while holding the leaf.
The leaf split cleanly.
"Feel that?" he asked.
Ino focused carefully.
She could sense the sharpness in the chakra flow.
"Your chakra becomes… thinner."
"Sharper."
Ren nodded.
"Exactly."
"Think of your chakra like a blade of wind."
"Focus on sharpness."
He cut several more leaves while letting her feel the chakra flow.
After a few demonstrations, he released her hand.
"Now try."
Ino picked up a leaf confidently.
"Just watch me."
---
Ren created a few shadow clones.
They nodded silently and walked toward the sealing chamber deeper inside the house.
Meanwhile, Ren watched the girls carefully.
With Six Eyes active, he could see their chakra circulation clearly.
He occasionally gave small tips.
"Hinata, focus the Lightning chakra in your fingertips."
"Ino, make your chakra thinner."
---
Hinata's leaf crumpled slightly.
Her eyes widened.
"I did it!"
Ren nodded calmly.
"That was fast but not enough. You have to crumple entire leaf."
Hinata smiled with determination.
"I will "
Ren nodded. "This traning takes Months you are already doing better than most ninja continue. "
"Now try to make it crumple faster."
Hinata nodded eagerly.
"Yes!"
She picked another leaf from the ground and continued practicing.
---
A few minutes later—
Ino suddenly shouted.
"why can't i do it!"
She protested in irritation.
"Stop acting like that. Ninjas need months to complete this." ren said.
"But it's so slow. I'm i even making any progress?"
He patted her head.
"you are just keep traning."
Ino grumbled but said with determination.
"Just you wait!"
She grabbed another leaf confidently.
---
Just then Ren paused.
Memories from one of his clones suddenly returned.
The clone had dispersed.
Ren nodded slightly.
"You two, come with me."
"The seals are ready."
Ino blinked.
"That fast?"
Hinata looked curious.
"What seals?"
---
The two girls followed Ren inside the house.
They entered a special room filled with sealing arrays and inscriptions across the floor.
Ren took out two prepared seals.
He gently placed one on each of their wrists.
"Now you don't need to carry storage scrolls anymore."
Ino blinked in surprise.
"A wrist storage seal?"
"That's super convenient!"
Hinata nodded.
"And very useful."
Ren smiled slightly.
---
Then Ren placed another seal on their foreheads.
It looked similar to Tsunade's famous Byakugō Seal.
"This seal will slowly store small amounts of your chakra whenever you are not using it."
He explained calmly.
"You can use that stored chakra later to create Shadow Clones."
"And train longer in chakra control and nature transformation."
Ino's eyes sparkled.
"You're the best teacher, Ren!"
Hinata bowed her head slightly.
"Thank you for everything, Ren."
Ren smiled faintly.
"Just make all this worth it."
"Become stronger."
"And don't die out there."
Ino immediately pouted.
"There you go ruining the mood again."
Hinata, however, looked completely serious.
"I won't."
Ren nodded approvingly.
---
Ren then handed each of them a pair of fingerless gloves.
"These have seals that will help with nature transformation training."
Both girls accepted them happily.
Neither of them realized how dangerous this knowledge actually was.
A seal capable of storing ninja tools and summoning them instantly was already a massive advantage.
The chakra storage seal was even more unbelievable.
Tsunade's Byakugō Seal required the user to create it themselves through years of mastery in fuinjutsu.
Even Shizune had failed to learn it.
Yet Ren had simplified the concept.
His version could be placed on others.
If he wanted, Ren could create an entire unit of elite Jonin or even Kage-level shinobi.
In real battles, chakra reserves often determined victory.
Monsters like Naruto who could spam jutsu endlessly were extremely rare.
More chakra meant longer fights, stronger techniques, and overwhelming advantage.
Entire wars could shift because of something like this.
And the nature transformation training seals were just as terrifying.
Most ninja spent years learning even a single nature transformation.
Even Kage trained for long periods to master them.
Ren chuckled quietly to himself.
"I wonder what their reactions will be when they find out someday."
---
Ren spoke again.
"One more thing."
"The nature transformation gloves stay here."
"You're not taking them back to the village."
Ino groaned slightly.
"Fine…"
Hinata simply nodded.
"That makes sense."
Ren wasn't worried about the wrist storage seals or chakra storage seals on them.
With Six Eyes, he had embedded microscopic concealment seals within them.
Even the Byakugan wouldn't notice them easily.
And the Hyūga clan certainly wouldn't activate their Byakugan just to stare at Hinata's forehead or wrists.
---
"Alright," Ren said.
"When you feel like you're running out of chakra, switch to Taijutsu training."
"Then rest."
"Refine your chakra and practice tree climbing."
He turned to Hinata.
"Hinata, watch me perform tree walking."
"Then explain it to Ino."
He stretched slightly.
"I need to test some seals."
Hinata nodded confidently.
"You can count on me."
Ino crossed her arms.
"Running away already?"
Ren chuckled.
He walked toward a tree and demonstrated tree walking slowly so Hinata could observe the chakra control.
"You two will follow this training routine from now on."
Then he disappeared instantly using Flying Thunder God.
---
Inside the sealing chamber, Ren appeared beside his clones.
Outside, Hinata and Ino stood quietly for a moment.
Ino sighed softly.
"He really is something."
Hinata nodded slowly.
"He is."
Ino kicked a small pebble.
"He's also an idiot."
"How much time did he spend building all this?"
Hinata looked around the peaceful island.
"But he did it for us."
Her expression became determined.
"So let's not disappoint him."
"Let's work harder."
Ino suddenly smirked.
"Ohhh?"
"Hinata not showing her possessive side today?"
Hinata immediately blushed.
"D-Don't get the wrong idea!"
She quickly added,
"We are still rivals."
"But we can't let his hard work go to waste."
Ino grinned.
"Yeah."
"Let's train so he won't have to worry about us."
Hinata nodded firmly.
"Yes."
