Originally, Kakashi had planned to wait until Jiraiya returned to the village, then ask him to take Orion to Mount Myōboku to learn Sage Mode.
But after their earlier conversation…
He gave up on that idea.
"Maybe when we go on future missions, I can try to locate the Three Great Sage Regions…"
"Someone in the shinobi world must know where they are."
Even though asking Jiraiya was no longer realistic, Kakashi still hadn't given up on finding a way for Orion to learn senjutsu.
He was genuinely worried—
If Orion's chakra kept growing at this rate, his body might not be able to handle it.
Orion walked to the lakeside and said calmly,
"I think you're worrying too much. I don't feel any discomfort at all."
"With my current physical condition, handling this level of chakra isn't a problem."
He understood his own body better than anyone.
If his body couldn't handle it—
That amount of chakra wouldn't even exist inside him.
And when the day came that his body reached its limit…
His chakra growth would naturally stop.
At the very least, for now—
His chakra was still increasing at an astonishing rate.
Almost doubling every day.
Though Orion could already sense that this rapid growth wouldn't last much longer.
Kakashi walked up beside him and said seriously,
"You can't take chakra lightly."
"There are plenty of shinobi in the ninja world who were severely injured because their bodies couldn't keep up with their chakra."
Then something crossed his mind.
"By the way… speaking of the Three Great Sage Regions—"
"You should already have your own summoning contract."
Orion glanced at him.
"I don't think I need one yet."
Kakashi sighed.
"Too bad my summoning beasts are more suited for tracking and reconnaissance… not really your style."
Orion instantly imagined a group of ninja dogs surrounding him—
And felt uncomfortable.
"Why don't you sign a contract with my summons first?"
"There's no limit to summoning contracts. For example, Sasuke has more than one."
"It all depends on whether your chakra can support it."
Orion smiled awkwardly.
"…I think I'll pass. Your summons probably don't suit me."
Kakashi thought about it and nodded.
"Fair enough."
"Once we find the Sage Regions, you can consider making a contract with them."
"The Minato Namikaze had a contract with Mount Myōboku."
"And Jiraiya-sama as well."
Orion suddenly asked,
"Sensei, if you were Minato's student… shouldn't your summoning contract be the same as his?"
"Since Jiraiya is his teacher, and Minato inherited his summons…"
"Why didn't you?"
Kakashi smiled.
"Because my summons suit me perfectly. I don't need another."
Then he looked at Orion with a grin.
"You already know what my summons are, don't you?"
He had just realized—
When Orion said they didn't suit him, it sounded like he already knew.
Orion didn't hide it.
"Yeah. I saw it while reading your profile."
In the Konoha library, information about famous shinobi was publicly accessible—
At least the basic details.
Kakashi didn't find it strange.
But he could tell—
Orion clearly didn't like his summons.
"So you don't like them, huh?"
Kakashi's tone turned slightly cold.
Orion immediately looked away, pretending to focus on the lake.
"Sensei… why don't you teach me some Water Style jutsu?"
"You should know quite a few, right?"
Kakashi chuckled.
"That's a terrible attempt at changing the subject."
"Still too young… You think ninja dogs aren't cool, don't you?"
Orion quickly denied it.
"No, no, they're great."
In truth—
It wasn't about liking or disliking them.
It was just that Kakashi's ninja hounds didn't provide much combat power.
They were excellent for tracking—
But in a real battle, Orion might end up protecting them instead.
Kakashi clearly didn't believe him.
"Hmph. Say what you want. You'll understand someday."
Then he asked,
"So, what kind of Water Style do you want to learn?"
Orion thought for a moment.
"I want something defensive."
"Defensive Water Style…?"
Kakashi nodded.
"Got it. I'll teach you Water Formation Wall."
"It's a B-rank jutsu. Moderate difficulty."
"For you… it should be effortless."
"Listen carefully. I'll explain the principles first…"
After a single explanation—
Orion understood it completely.
Kakashi didn't demonstrate.
Instead, he asked,
"If I don't show you… can you figure it out on your own?"
"With your talent, it shouldn't be a problem."
He wanted to test Orion's limits.
After all—
Orion had copied the Water Dragon Jutsu mid-battle before.
Orion nodded and walked to the lake.
He focused his mind and gathered chakra.
Then—
He clapped his hands together and began forming seals at high speed.
"Water Style: Water Formation Wall!"
The moment his chakra surged—
The lake water reacted.
"RUMBLE—!"
Water was forcefully drawn upward, rushing toward him.
"WHOOSH—!"
A massive current formed around Orion, spinning violently.
In an instant—
It turned into a gigantic water vortex.
The surrounding grass was flattened by the pressure.
The ground was carved into grooves by the rushing water.
Within seconds—
A vortex over ten meters wide surrounded Orion.
Watching from afar, Kakashi's mouth twitched.
"…Is that still Water Formation Wall?"
"That's basically a combination ninjutsu."
"There's already Wind Style mixed into it…"
"And the scale is ridiculous."
Still—
Compared to Orion's previous techniques—
This wasn't even that shocking.
Standing at the center of the vortex, Orion clasped his hands together again.
His eyes sharpened.
The swirling water suddenly stopped—
Then gathered in front of him.
A towering water barrier formed.
Over ten meters tall.
Dozens of meters wide.
Kakashi smiled.
"Now that—that's Water Formation Wall."
"The previous one clearly had Wind Style mixed into it."
He could tell—
That first version was Orion's own improvisation.
A fusion of Water and Wind.
For ordinary shinobi—
Messing with jutsu like that was dangerous.
It could even backfire.
But for Orion?
That wasn't an issue.
His chakra control was simply too precise.
And after witnessing Orion's mastery over Lightning Style earlier—
Kakashi wasn't surprised anymore.
