Reiji Arata couldn't help but smirk slightly as he watched Naruto, who was blushing yet completely engrossed in the magazine.
He knew very well that kids in the Naruto world matured early.
Before he transmigrated, Reiji himself was probably still twelve years old, sitting in front of the TV watching Pleasant Goat.
Snap!
Naruto flipped through the magazine quickly, then shut his eyes and pressed his hands together into a seal.
"Hey, Reiji! Watch this transformation!"
A puff of white smoke burst out.
What appeared was a fair-skinned, long-legged woman resembling Nico Robin in a sultry nurse outfit—white stockings hugging her legs and a giant syringe in hand, her pose exaggeratedly suggestive.
The scene was… vivid, to say the least.
Naruto gave a shy smile and purred, "Reiji-kun, don't stare so hard~ You'll make me blush. Want me to poke you with this~?"
Reiji, surprisingly, didn't get a nosebleed. In fact, he didn't even seem shocked.
After all, as a seasoned connoisseur, he had spent many late nights studying and… thoroughly analyzing Nico Robin materials before reincarnating.
He just gave Naruto a calm nod and a thumbs-up.
"Truly… a man of culture," he said sincerely.
Though Naruto's clone technique was still garbage—just like Reiji's early attempts—his skill with the Seduction Transformation was undeniably top-tier.
[Ding! Congratulations, host. Guidance mission complete. Reward: Uzumaki Physique Lv1.]
Without hesitation, Reiji shouted in his mind: "Upgrade!"
[Congratulations. Uzumaki Physique upgraded to LvMAX. Bonus unlocked: Chakra Control boost +100%.]
[Note: The 100% chakra control boost will activate after chakra is used 100 times.]
Immediately, Reiji felt a surge of warmth spread from his lower abdomen and navel throughout his body. Strength flowed through him in waves.
"Not bad at all… so this is the change brought by a max-level Uzumaki Physique?" he muttered, amazed.
Naruto, back in his regular form, grinned and handed him a takeout container.
"Hehe, Reiji! You're seriously a genius. You must be hungry after gathering 'research materials' all day. I brought you Ichiraku's signature miso pork ramen—eat up while it's still hot!"
Reiji returned to his senses and smiled. As he slurped the ramen, he asked Naruto about the original body's life in this world.
Turns out Reiji Arata's body in the Naruto world shared a similar fate to Naruto's—both his parents died protecting the village during the Nine-Tails attack twelve years ago.
The two orphans grew up as neighbors and best friends, more like brothers than anything else.
Reiji was actually satisfied with this setup.
After all, in the original story, Naruto was shunned by the villagers as the dangerous Nine-Tails Jinchūriki. He never got the love and care he deserved as a child.
If his presence could bring even a little comfort and warmth to Naruto's lonely life, then maybe this reincarnation wasn't so bad.
After finishing the ramen, Reiji stood up, ready to head home.
Naruto didn't stop him—he was too focused on practicing his newly learned jutsu.
Once Reiji returned home, he immediately closed all the doors and windows.
The place was about the size of the small apartment he used to rent before transmigrating, but much cleaner and tidier than Naruto's home.
He quickly opened his system panel.
Now that he had the Uzumaki Physique, his chakra reserves had skyrocketed.
[Chakra: 99,000 – 100,000 units (~100x Kakashi)]
With this much chakra, he needed precise control to manage it properly.
Reiji retrieved the Top 100 Model: Illustrated Guide magazine from his interdimensional scroll.
Then he began practicing the Transformation Seduction Technique repeatedly—to both amuse himself and build up his chakra control.
"Transform!"
Poof! Poof! Poof!
[Transformation successful. Chakra used. Chakra Control +1%]
"Heh… it works."
He kept transforming again and again. His chakra pool didn't feel strained at all.
[Chakra Control +33%]
[Chakra Control +66%]
[Chakra Control +100%]
(Don't ask me how it just did.)
He transformed into every model in the magazine. By the time his control maxed out, night had fallen.
Exhausted, Reiji collapsed into bed and fell asleep.
The next morning.
The sun rose in the east, casting a soft glow across the village.
Reiji woke up, washed his face, and got ready to train.
He still only had a C-rank offensive fire jutsu and a B-rank defensive earth jutsu. He hadn't even learned the basic Three Academy Techniques yet.
At this level, he was still far from being able to handle real threats in the ninja world.
With the main story about to begin, he needed to raise his power—fast.
Just beneath the Hokage Rock was a large training forest used by Konoha's shinobi.
Thanks to last night's chakra control boost, Reiji could now focus chakra to his feet effortlessly.
Whoosh!
He jumped out the window, ran up a tree, and darted toward the forest.
"Ohh! Fifty more laps! Burn bright, my youth!!"
Reiji heard an energetic shout in the distance.
Sure enough, a green blur passed him—a boy doing laps around the forest on his hands.
Thick eyebrows, round eyes, green jumpsuit, and a bowl-cut hairstyle.
Rock Lee.
One of the future Twelve Konoha Guardians. A passionate, hard-working ninja who specialized purely in taijutsu.
In the original series, Lee didn't know a single genjutsu or ninjutsu, yet his dedication and strength helped him defeat early-stage Sasuke with ease during the Chūnin Exams.
Reiji admired him. He always thought that if Lee had landed the final blow on Madara during the war instead of Gai, it would've been the perfect ending to the youth-without-regret narrative.
Unfortunately, Lee was shafted later in the series—limited to Six Gates only.
To Reiji, this was proof of one brutal Naruto-world law:
Those who work hard lose to those with talent.
Those with talent lose to those with bloodlines.
And those with bloodlines lose to those with talk-no-jutsu.
But maybe—just maybe—with his system cheats, he could finally break that cycle.
Just as Reiji was about to hop down from the tree to greet Lee, the system chimed again.
