With Kaito's five-year-old body, he simply couldn't bear it. Even if he could, he would be seriously injured and need to recuperate for a long time.
Kaito had been training in this space for nearly a year now, and his physical strength was on a completely different level than it was a year ago!
The chakra in his body had also grown from its initial thread-like size to the thickness of a thumb. The growth had been remarkably fast!
With Kaito's current physical skills and chakra reserves, he had completely reached the level of a Konoha Genin.
After his breathing gradually slowed, Kaito stood up from the ground and walked toward the woods not far from Konoha.
He didn't let the system switch directly to forest mode. First, he had just undergone intense training and needed to adjust his state. Second, he needed to relax a bit.
After all, what he was about to practice was the Lightning Release Body Enhancement Technique used by the Cloud Ninja Village—an advanced jutsu, possibly equivalent to an S-rank technique. It wasn't something to be rushed.
Besides, he had only read about it on the official Naruto website before he got transported to this world. He wasn't even sure if it was real and needed to test it for himself.
Half a day later, after Kaito had recovered, he sat cross-legged on the ground and began to practice the technique based on the Lightning Release Body Enhancement theory he remembered.
With a thought, the lightning-element chakra—granted by his Devil Fruit—began to flow into his right arm. He compressed the lightning chakra, forming a smooth current that flowed both inside and outside his arm, then released control.
Crackling!!
Blue lightning began to flicker and intensify around his arm.
Kaito focused intensely. In the next moment, his right hand transformed into pure lightning—an elemental shift.
After the surging electricity calmed, Kaito's hand returned to normal.
"It works!" he smiled, showing no disappointment from the earlier setbacks.
Over the course of his training, Kaito had thought a lot about the risks of Lightning Release Body Training. Eventually, he came up with a solution: transform his body into lightning at the moment of overload to minimize damage.
Once this idea was in his head, he couldn't let it go. Now, having tested it, the results were better than expected.
After becoming lightning, his hand was only slightly numb—not charred or destroyed like others who mishandled Lightning Release. It was totally within his tolerance.
Of course, Kaito knew this didn't make him invincible. Elementalization couldn't fully protect him from ninjutsu, especially not in a world full of powerful ninja.
(Physical Attacks would still pass through him, So it ain't a nerf. Cos imagine someone like Madara using Great Fireball on the current him, Of course it would hurt or probably kill him)
"I compressed it too much last time. Let's go with less this time."
He hesitated briefly, then gathered lightning chakra into his arm again—controlling and compressing it more carefully this time.
Crack! Crack!
Lightning sparked again, and Kaito withdrew his now-numb hand. "Still too much… Just a bit less next time."
---
One day passed. Then two. Still, Kaito didn't stop.
When his right hand went numb, he switched to his left. When that one numbed, he went back to the right. Again and again, like a stubborn old ox unwilling to give up until he mastered the technique.
On the grass in the woods, Kaito stared at his lightning-covered arm. The chakra gradually faded, revealing a normal, uninjured arm.
"Finally succeeded." His tired expression gave way to joy.
He clenched his fist. His arm wasn't hurt, just slightly numb. It even felt tougher than before.
With the lightning chakra amount figured out, things would only get easier from here.
Kaito sat cross-legged. Chakra surged through his body, transforming into lightning element and spreading outward.
The electricity began to erode and stimulate every cell. If he didn't control it, it would damage him. But at the perfect balance, it tempered his body.
Under this stimulation, Kaito felt heat swell through him. Every cell was being refined and strengthened.
He knew then—he had completed the first stage of Lightning Release Body Enhancement.
In the days that followed, Kaito continued refining the technique.
---
Time flew. Outside, seven days passed. Inside the training space, Kaito had been at it for 70 days.
His life became a loop: physical drills, chakra refinement, Lightning Release body training.
Thanks to the Lightning Release Body Enhancement technique, Kaito's physical strength had doubled over the 70 days.
His chakra reserves grew thicker and more stable.
The duration of his lightning training also increased—from one hour to an hour and a half.
But recently, Kaito had hit a bottleneck. His body had adapted to the lightning chakra; the growth slowed.
Now he had two options:
One. Extend lightning chakra outward to form a thin layer around his body—a technique known as Lightning Chakra Mode, famously used by the Fourth Raikage to fight Uchiha Sasuke.
Two.Increase the density of lightning chakra during training to push his limits further.
Kaito chose the first. His body had advanced too quickly, and he needed time to adjust. This was a good chance to solidify his base.
With his decision made, he executed it immediately. He didn't want to waste a single opportunity to get stronger.

He'd start going to the academy soon
Be patient.
