The moment Ya Yu looked at him, he knew Ya Yu had left a Flying Thunder God mark on Zabuza.
In a moment of urgency, Kakashi could only trust Ya Yu, believing that Ya Yu could hold Zabuza back.
So he used his Sharingan to engage Zabuza in a Ninjutsu standoff, creating an opportunity for Ya Yu.
The result was obvious, Ya Yu did not disappoint!
At the same time, everything Ya Yu had just displayed shocked Kakashi even more!
In his brief clash with Zabuza, Ya Yu had used the Eight Inner Gates, Flying Thunder God, and Water Release.
He used each technique with ease, as if it were second nature!
Even the speed of his hand seals for the Water Release was faster than his!
Genius!
Besides that word, Kakashi couldn't think of a more suitable one for Ya Yu.
"What happened just now? Did you see clearly?"
Naruto stared blankly at Sasuke next to him.
He only remembered Zabuza swinging his swords a few times near him.
He exchanged a Ninjutsu with Kakashi-sensei, and then was inexplicably controlled by Ya Yu!
"I didn't see exactly how he did it."
Sasuke put his hand on his forehead.
He had already realized the gap between himself and Ya Yu!
This wasn't something that could be bridged with just effort!
What did this guy eat to grow up, knowing so many Ninjutsu!
Was his prenatal education all about learning hand seals?!
On the other side, Zabuza, trapped in the water prison, felt a million regrets in his heart.
But he didn't know how to express them, ending up with his face flushed red.
Shame!
Such shame!
He, the Demon of the Mist, known for silent assassination in the ninja world, was taken down in a couple of moves by a Leaf shinobi!
Now he was humiliatingly trapped in a water prison!
Zabuza could only feel the shame overwhelming him!
"Kakashi-sensei, what should we do with this guy?"
Ya Yu asked Kakashi while controlling the water prison.
"It's best to leave it to the Mist Village. This person is a rogue ninja from the Mist, and they will have specialized tracking ninjas to handle this kind of problem."
Kakashi replied after a moment of thought.
"Don't we just eliminate him directly, to avoid any future trouble?"
Ya Yu asked.
Kakashi explained: "Directly eliminating him might cause unnecessary conflict."
"A ninja's body contains secrets of their respective villages' Ninjutsu, Chakra attributes, even the ingredients of any secret medicines they've used."
Kakashi continued, "Suppose my body fell into the hands of another village, the secret of the Sharingan would be quickly discovered, and even our Ninjutsu might be leaked."
"I see, then why don't we quietly dispose of him, no body, no one will know?"
Naruto chimed in.
Just then, a voice came from a large tree nearby: "Young man, I heard what you said."
Ya Yu and the others looked up towards the voice, and saw a masked ninja standing on top of the tree crown.
"That must be the Mist Village's tracking ninja."
Kakashi glanced at the mask and explained.
"Tracking ninjas, specifically responsible for dealing with rogue ninjas who escape the village."
"They can dispose of the rogue's body in a proper way to prevent their own village secrets from being leaked."
Kakashi further explained.
"So that's it."
Ya Yu nodded in understanding.
The Mist's tracking ninja jumped down to the surface of the water next to Ya Yu.
He looked at Ya Yu, who was young but capable of trapping Zabuza with Water Prison, with some surprise.
Then, the tracking ninja took out a few thin needles from his equipment bag and said to Ya Yu: "Please release the Water Prison."
"This way, won't he run away?"
Ya Yu asked.
"Don't worry, I'll control him."
The masked Mist ninja said confidently.
Ya Yu looked at Kakashi-sensei, and after receiving permission, nodded in agreement.
He then withdrew his hand from the water surface, while remaining vigilant of the Mist ninja.
"Splash!"
The water ball binding Zabuza instantly dissipated!
As soon as the Water Prison was released, the Mist's tracking ninja immediately used the few thin needles to accurately pierce Zabuza's neck!
Zabuza's body immediately slumped to the ground, losing all signs of life.
"Thank you for your assistance, I will handle Zabuza's body and the Kubikiribocho properly."
The tracking ninja said, and disappeared with Zabuza's body.
Naruto on the shore was indignant: "Really! The person we've been fighting so hard against for so long, and he's taken care of by someone else!"
Sasuke stood there with his arms crossed, looking calm: "What are you mad about, Ya Yu did most of the work."
Naruto was speechless.
"I'm just feeling sorry for Ya Yu!"
He finally said.
Tatsuya-san stepped forward: "Okay, thank you everyone, my house isn't far from here, let's go."
"We've been walking for so long, I really want a bowl of ramen."
Naruto said, rubbing his empty stomach.
"I want braised pork..."
Ya Yu simply stated his wish.
"Ah? Never heard of that dish!"
Tatsuya-san was surprised.
"Neither have I."
Kakashi scratched his head, he had never heard of this dish in all his years in the Leaf.
"You guys don't even know about it?"
Ya Yu was slightly surprised, and began to introduce: "Braised pork is made with pork belly with alternating layers of fat and lean, seasonings include..."
"When it's done, it's fragrant, sweet, soft, rich in nutrients, fatty but not greasy, melts in your mouth, a delicacy!"
"Although I've never heard of it, it sounds delicious!"
Sasuke showed a longing expression.
While the gluttonous Naruto was already starting to swallow: "Ya Yu, you know how to cook, right? When will you make us some, I really want to eat it!"
Ya Yu responded: "Why don't you learn to make it yourself?"
..
Meanwhile, on another side.
The Mist's tracking ninja carried Zabuza's body to a hidden forest.
He then pulled out the needles from Zabuza's neck.
"Cough... cough..."
Zabuza coughed a couple of times and recovered from his fake death state.
"The Copy Ninja Kakashi is indeed something else, he was able to push Zabuza to such a desperate situation."
The tracking ninja exclaimed.
Although he had witnessed Ya Yu trapping Zabuza with the Water Prison, he thought it was Kakashi's arrangement.
"Actually, Kakashi hardly moved a muscle just now."
Zabuza, in shame, gritted his teeth, "It was that kid, not only does he know the Flying Thunder God technique, but he's also proficient in Water Release..."
The masked tracking ninja opened his mouth in shock: "The Flying Thunder God Technique? That kind of powerful space-time Ninjutsu is only..."
Zabuza raised his hand to interrupt his unfinished words: "Don't remind me, I know."
"Also, can you take off your disguise mask."
