The Spoiling Little Sister System.
Just from the name, its function was obvious—
as long as he interacted with, or engaged in intimate contact with, a "little sister," he could obtain various rewards.
Neji was stunned for a moment… then broke into a grin.
Now this felt right.
Since he had transmigrated here, how could he not have a system to help him?
Everyone knew the rule:
a transmigrator without a cheat was like going into battle without a weapon—completely useless.
At that moment, the cold mechanical voice echoed in his mind once more.
> "The host embraced Hyuga Hinata."
"Reward obtained: Byakugan (100% Purity)."
"What?!"
Neji was shocked.
A Byakugan with 100% purity?!
At first glance, this reward didn't seem especially practical—but in reality, it was one of the key prerequisites for awakening the Tenseigan!
The Tenseigan was an ultimate dōjutsu that could only be awakened by combining the chakra of the Ōtsutsuki clan with the Byakugan of the Hyuga clan. It possessed power capable of destroying—and creating—entire worlds.
It was the final evolution of the Byakugan, standing on the same level as the Rinnegan inherited from the Sage of Six Paths. Both were terrifying eyes with unfathomable power.
The Rinnegan was the ultimate evolution of the Uchiha clan's Sharingan.
The Tenseigan was the ultimate evolution of the Hyuga clan's Byakugan.
However, awakening the Tenseigan was extremely difficult.
The Byakugan itself wasn't the problem—but he still needed the chakra of the Ōtsutsuki clan.
In other words, Ōtsutsuki blood.
Although the Hyuga clan did possess Ōtsutsuki blood, after countless generations, it had become incredibly diluted.
Both conditions were indispensable. Otherwise, Ōtsutsuki Toneri wouldn't have needed to come all this way just to steal Byakugan.
Thinking about it, Neji let out a quiet sigh.
Setting everything else aside—
if he could gather both conditions early and awaken the Tenseigan, he'd basically be able to do whatever he wanted in this world.
"Forget it. I should be realistic. Being overly ambitious won't get me anywhere."
Putting those thoughts aside, Neji decided to test the power of this pure Byakugan while Hinata was still unconscious.
"Byakugan!"
His eyes snapped open, veins instantly bulging around his temples.
The world changed.
Everything within a two-hundred-meter radius became crystal clear—every movement, no matter how slight, was perfectly captured.
"As expected of a high-purity Byakugan… The perception is sharper. The precision is higher!"
At this point in time, the original Neji could only see about fifty meters around himself.
"And…"
Neji smiled faintly.
"The blind spot behind the first thoracic vertebra… it's gone."
A pure Byakugan was truly terrifying.
"Unn…"
Just then, Hinata—who had fainted earlier—slowly woke up.
"You're awake," Neji said calmly, deactivating his Byakugan.
Outwardly, he was composed.
But the excitement in his heart was impossible to hide.
Hearing his voice, Hinata immediately recalled what had just happened.
Her porcelain-like face flushed bright red, and steam practically rose from the top of her head.
"E-ehhh…"
Adorable.
Neji looked at the small girl in front of him and sighed sincerely.
Was the original Neji really that dense, completely unaware of the advantage of being close to someone?
…Thinking about it, yeah. He really was.
But that was fine.
From now on, he'd take good care of Hinata.
As for Naruto…
go spend the rest of your life chasing Sasuke.
"N-Neji nii-san… I-I'll head back first…" Hinata whispered.
As soon as she finished speaking, she covered her face and ran off in a panic.
Neji watched her retreating figure and couldn't help laughing.
This girl was way too shy.
"System," Neji asked, puzzled, "how exactly were you activated?"
> "The system's activation condition is: the host engages in intimate interaction with the opposite sex."
"I see." Neji nodded. "Then what functions do you have?"
> "This system is called the Spoiling Little Sister System."
"As long as the host interacts with the opposite sex, random rewards may be obtained."
"Rewards are not limited to the Naruto world, nor are they restricted to non-living objects."
"However, rewards are mostly related to the opposite sex interacting with the host."
"Additionally, the system includes built-in storage space capable of holding any non-living object or system reward."
So that's how it works!
No wonder it gave him a pure Byakugan.
Neji chuckled, his face full of excitement.
This meant he didn't even need brutal training.
As long as he chatted with Hinata every day, spent time with her, maybe played a few games…
He could steadily gain powerful rewards.
Effortless strength.
He could literally lie down and win.
He did value hard work—but who would refuse power that came without effort?
Wait.
"As long as I interact with the opposite sex…"
Neji suddenly frowned. "System, aren't you the spoiling sister system? Shouldn't rewards only come from interacting with little sisters?"
He rubbed his chin suspiciously.
After all, everyone knew he only had two little sisters.
Hyuga Hinata.
Hyuga Hanabi.
If that was the limit, the scope felt a bit narrow.
> "Host, please correct your understanding of your status."
"Always remember one thing."
"They are all your little sisters."
"Oh?"
Neji's eyebrows shot up.
This system was… bold.
That line sounded eerily similar to a certain phrase:
"You're all my little brothers."
If other people heard this, he'd probably get beaten half to death.
After practicing alone for a while and adapting to chakra control and Byakugan usage, Neji moved to the other side of the training grounds.
Here, numerous training dummies were set up, each engraved with the sixty-four chakra points of the human body.
Once someone entered their range, the dummies would activate.
They could only be stopped by striking all sixty-four chakra points.
It had to be said—the Hyuga clan put tremendous effort into cultivating their younger generation.
At the very least, Neji had never heard of other clans possessing such specialized training facilities.
They truly deserved their reputation as Konoha's second-largest clan.
Neji paid little attention to any of that.
He had only come here to test his Eight Trigrams Sixty-Four Palms.
With the pure Byakugan enhancing him…
Neji smiled faintly and leapt straight into the center of the formation.
Dozens of training dummies activated at once and attacked him simultaneously.
He didn't dare underestimate them.
It was said that not even a jonin could completely avoid their attacks.
"Byakugan!"
"Eight Trigrams Sixty-Four Palms!"
The pure Byakugan allowed Neji to instantly grasp the dummies' movement patterns and attack trajectories, drastically improving his reaction speed.
At the same time, it dramatically increased his accuracy.
With near-360-degree vision combined with his swift, precise palm strikes, his attacks almost never missed.
Even when surrounded and attacked from all sides, he could use Eight Trigrams Palm Rotation to deflect their assaults.
"The Hyuga clan's taijutsu—offense and defense combined—is truly formidable," Neji muttered.
After one full round of training, he had been struck around twenty times.
But the gains were undeniable.
At the very least, he was now thoroughly familiar with chakra control and the Hyuga clan's taijutsu.
"System," Neji said calmly,
"open my status panel."
