Makoto didn't refuse Hanabi's request and went with her to the newly built indoor training ground in Amegakure.
The indoor training ground was designed for practicing technical ninja arts.
For large-scale destructive jutsu, outdoor practice was still necessary (unless they wanted to rebuild the tower every week).
Hanabi's initiative in asking for training reminded Makoto that he still had Momoshiki's Disc in his inventory and needed to find time to figure out how to extract the Otsutsuki chakra from it.
Ideally, it could be used like a rechargeable battery for sustainable extraction.
But for now, it had to be set aside.
Orochimaru and Tobirama had just completed the "Rinnegan Hacking Project," and the next step was to treat the old, weak, sick, and disabled.
Kimimaro Kaguya and Ameyuri Ringo couldn't wait any longer—both would soon pass away if left untreated.
Moreover, Hanabi's current strength indeed needed improvement.
Letting Hanabi directly activate the Tenseigan right now was like giving a loaded bazooka to a toddler.
It reminded him of Daemon in Boruto.
With a terrible personality, Daemon obtained a low-tier "Miracle" ability through the Otsutsuki God's remains, capable of reflecting any attack from someone with "killing intent" toward him.
Not to mention Daemon's ability had a major limitation—he had to touch the opponent first (or be touching someone else).
But even if he did, so what?
Reflect attacks with killing intent?
Sorry, but disciplining a brat with a terrible personality is as simple as popping open a can of soda—why would there be any "killing intent"?
Facing such an ability, not just Makoto, but even Uchiha Madara—who was just criticized by Tobirama for "only bullying the weak"—could break Daemon's limbs with the mindset of "What adult takes a child seriously?"
He would crush him with the intent of "education," not "murder," completely bypassing the reflection.
The Boruto series has this bizarre characteristic where heroes and villains stubbornly refuse to kill each other, as if they were playing house.
Completely lacking life-or-death urgency.
But it's understandable, since Boruto is essentially about a bunch of kids messing around.
Look at Code—he created Ten-Tails Fission Beings on his own, only to find he couldn't control them, and they ended up being stronger than him.
So, gaining power is fine, but you need the mentality to match that power.
Otherwise, you're just a comically oversized infant with a gun.
...
Inside the Arena.
At Makoto's signal, Hanabi began demonstrating the newly developed technique she had mentioned earlier.
Makoto and Fuu sat in the spectator seats, watching Hanabi activate the equipment.
Beep. Beep. Whirrr.
The targets began moving faster and faster, sparks flying from the rails beneath them.
After completing the setup, Hanabi retreated a considerable distance and turned her back to the targets.
"Byakugan!"
"Lock-on!"
After activating her eye power, Hanabi spun around, extending one index finger from each hand like pistols.
Pew! Pew! Pew!
She began precisely shooting invisible bullets at the targets.
The rapidly moving targets, numbered 1 through 9, were destroyed in sequence by Hanabi's attacks.
"Phew."
Hanabi playfully blew the "smoke" from her fingertips and ran up to Makoto, tilting her chin up proudly.
"So? How was it?"
"Uh... quite impressive."
"I saw that Orochimaru has a subordinate from the Hozuki Clan who uses the Water Pistol Technique, shooting high-pressure water bullets from his hands."
"When I saw that, I thought I could try something similar too."
"My chakra isn't quite sufficient for the massive Eight Trigrams Vacuum Palm spam yet, but fingertip-sized compressed air bullets are definitely manageable—it just requires extreme chakra control."
Hanabi explained her logic.
Regarding combining the Byakugan with ranged attacks, Makoto had discussed this with her long ago.
The fundamental ability of the Byakugan is "Lock-On."
With this 360-degree x-ray vision, one can accurately perform precise strikes even in high-speed combat.
But using it only for melee is wasting its potential.
If you have an Aimbot, why are you using a damn knife?
However, among the current abilities of the Hyuga clan, only the Eight Trigrams Vacuum Palm qualifies as ranged attack.
And even though the Vacuum Palm is considered ranged, it's more like a shotgun blast—wide area, short range.
In contrast, the "Eight Trigrams Vacuum Finger" that Hanabi developed acts like a sniper rifle.
By compressing chakra into a tiny point, she has more than doubled the effective range and added "piercing" properties.
"This is good. Keep practicing diligently," Makoto praised her.
In Tenseigan Mode, she would essentially function as a floating artillery attacker.
This kind of precision training was perfect.
"Mhm!" Hanabi, having received approval, nodded her head excitedly.
"So what do you want me to help you train with now?"
"Close combat, of course."
Hanabi waved her fist and glanced at Fuu beside her. "Didn't you tell me that ranged fighters are in danger if enemies get close? So it's best not to neglect Close combat either."
"Alright, let's go then."
Makoto had no objections to sparring with Hanabi.
He hopped over the railing into the arena.
Since this was training, Makoto naturally had to control his power and speed. Instantly defeating Hanabi wouldn't count as training—it would just be bullying.
The two began their exchange.
Whoosh.
The moment Hanabi made her move, Makoto could sense something different.
It seemed Hanabi had indeed taken his words to heart, no longer limiting herself to the Gentle Fist.
This strike clearly fell within the realm of the Strong Fist.
However...
Makoto raised his hand and deflected the attack with a backhanded slap to her wrist.
Slap.
"Kyahh~!" Hanabi let out a soft cry after being struck.
This was perfectly normal reaction since it stings.
Hanabi continued her assault.
Slap.
"Un~!"
Spank.
"Ahhh...!"
As the person involved, Makoto didn't find it particularly strange—after all, it was natural to make a sound when hit or exerting effort.
Moreover, Hanabi wasn't exaggerating; his strikes were light, and her responses were equally soft.
But to an observer...
...
In the Spectator Seats.
Fuu's antennae twitched.
'I may be blind to social cues... but what exactly is this sounds?'
This was utterly embarrassing!
If she hadn't witnessed it with her own eyes, watching the two "sparring" and "fighting," with the occasional wet slap sound followed by Hanabi's breathless moan...
Who could guess what they were actually doing?
'Wait a minute!' Fuu suddenly thought of something.
'When I sparred with Hanabi, it wasn't like this at all! She was fierce!'
'Could it be... that during our last encounter, I accidentally used the Seven-Tails' scale powder, causing Hanabi to develop a severe throat allergy?!'
'That won't do! Hanabi is my best friend!'
"Hanabi! Wait for me—I'm going to find a Medical Ninja right now! Don't die on me!"
Fuu screamed toward the training ground and dashed toward the exit at Mach 1 speed.
"Huh?"
Inside the training ground, Hanabi froze mid-punch upon hearing this.
'Why look for a Medical Ninja? I'm not even injured?'
