Twenty minutes passed with Yuta attempting the clone technique over and over, each result more disappointing than the last.
Malformed clones appeared and dissolved within seconds, some missing entire body parts, others flickering like dying lightbulbs before vanishing into smoke.
Kakashi had long since returned to his orange book, occasionally glancing up with decreasing interest as Yuta's failures continued.
"Your chakra control is..." Kakashi paused, flipping another page.
"Problematic."
Yuta wiped sweat from his forehead, frustration building.
"I can sense it, I just can't seem to..."
"Maybe ninjutsu isn't your strong suit," Kakashi interrupted.
"We'll end here for today, I'll oversee when you have any progress" Kakashi said and then disappearing in a smoke just as easily as he came.
Yuta wasn't disappointed however.
Kakashi reminded him of his sensei Gojo except he wasn't that detached.
Yuta found his way home and spent the rest of the day trying to make the clone jutsu successful until he exhausted the chakra he had absorbed.
He immediately tried to absorb more but felt a sharp strain to his brain, it was a sting of pain but he understood what it meant.
He likely could not absorb chakra almost immediately again, he had to wait out his body to get used to it, the chakra usage.
Which frankly was weird to him because if asked he was confident he had a strong body.
The next day went by with kakashi only coming by to seif there was any improvement and with each time he came, the more detached he was showing his subtle dissatisfaction until by the end of the week.
When kakashi appeared again he instinctively got into the room and asked without looking in the direction of Yuta.
"Any progression?"
"Yes" Yuta replied
Kakashi nodded and then turned around to leave only to turn around again and stare at Yuta or more correctly the two Yutas.
Allowing himself the brief stun, kakashi gestured for them to meet at the training ground as before and yuta modded only for kakashi to immediately flicker away.
Not long after Yuta appeared at the symbolic training ground with wooden dummies and target practices.
Where Kakashi was already sitted and leisurely reading his book.
"You're late" Kakashi said
"I apologize" Yuta said
"Show me" Kakashi said
And then Yuta proceeded to weave the hand signs which promptly produced an exact clone by his side.
Kakashi stared at him for a while and then the clone and then said.
"That's perfect, this put you slightly above your peers though that means non Shinobi. However I am curious to how you are able to do it, I thought I would have to intervene." Kakashi said.
"My original energy was just more dominant, I had to let some of it go to be able to smoothly control this chakra, keeping both energy reserves at 50/50"
"I see, I hear you call this cursed energy used by sorcerers. How does it work?."
Yuta looked at kakashi for a second and sat down on the grass.
"It is a broad field of study and so far I can say that it works almost exactly like Chakra, I haven't explored enough to know where it's limitations are at." Yuta said.
'He is dragging a bargain, smart kid, he knows his worth, he may not be lying when he told Asuma he has been a borrowed weapon before'
"Jutsus, Have you tried performing jutsu with your cursed energy to see its effect"
"There is none" Yuta replied
"More precisely, we use techniques rather than jutsus, each person has their own unique technique, think of cursed energy as a bomb, it has way more strict requirements for advanced use, or else an irreversible damage happens so if possible I am leaning more to a normal use"
'So like a Forbidden jutsu for specific persons and even then it's highly dangerous'
"I understand. However you will not be able to become a Shinobi by only being able to perform Jutsu Yuta. Technically by doing this you would have officially passed the academy, however you will need to go and learn the theoratical part of this world... Later in the library. Now for my personal test" Kakashi said as he stood up.
"Personal test?" Yuta asked
"Indeed, you learning ninjutsu was to determine you could use ninjutsu and that was merely the hokages requirement to determine your use." Kakashi said.
"Incase you haven't noticed, as there are people willing to accept you here, there are also people who aren't willing to do so, and trust me this world is different from yours maybe much worse, you're only a threat when alive" kakashi said.
"Alright I've said too much, Your test is to get these bells off me, Fight me like your life is on the line" Kakashi said as he stood on guard looking at Yuta as yuta stared at him and the bell.
"Are you sure about that?" Yuta asked while looking at kakashi however he was considering whether or not to bring Rika into the battle.
But there was only few people who could handle Rika without causing a massive destruction.
"You have 20 minutes" Kakashi said in reply as he dropped an alarm on the practice dummy.
