Next day...
Naruto led Kawaki to the training clearing where Boruto, Mitsuki and Sarada were already waiting
"Why did you make me come here?" Kawaki asked
"You have experience in using Karma, I want you to pair with Boruto"
"Do I really have to fight this bastard?" Boruto asked
"Yes, I want to see what exactly this Karma is"
Boruto faced Kawaki
"I just don't know how to activate it, then I activated Karma under the influence of emotions seeing this guy kill Miyuki"
"Pathetic" Kawaki commented activating Karma, then Boruto's Karma was also activated
"How did you do that?"
"I don't know why, but it seems our Karmas are connected in some way," said the teenager
"All right, start sparring"
Boruto first rushed to attack Kawaki, the former member of Kara easily blocked his attack, then Kawaki kicked Boruto several meters backwards with a kick to the stomach.
"Kage Bushin No Jutsu!"
Boruto created several clones which he sent to Kawaki, the teenager easily destroyed them. At this time, the real Boruto jumped up trying to attack Kawaki, Kawaki dodged his blow, then kicked Boruto in the stomach, the blonde spat blood falling to his knees
"I think I won"
Suddenly, Boruto jumped out hitting Kawaki in the chin, the Hokage's son quickly created two clones that kicked Kawaki in the back, knocking him even higher, the real Boruto grabbed Kawaki's leg and threw him to the ground
"For someone who can't use Karma, you fight well," Kawaki admitted reluctantly
"From what I've noticed, it's Karma that enhances the user's strength, the rest I owe to training," replied Boruto
"Okay, that's enough" said Naruto "Boruto, you've made progress in your fighting style"
"Thanks"
"While Kawaki, maybe you'd like to become a Konoha shinobi."
"Shinobi?" Kawaki raised an eyebrow at the Hokage's question
"Being a shinobi, you can go on dangerous missions with your team"
"Sorry, but I prefer to do the job alone"
Naruto just sighed "I understand, it will take some time before you get used to the new situation"
This time, Yosaru was standing in front of the waterfall with the new Sharingan
"Are you used to those eyes?" asked Amado
"Yes. I've seen those bastards from the Uchiha clan using the Sharingan many times, now I can finally feel the power of this doujutsu"
"I implanted you with Otsutsuki cells, so you don't have to worry about the negative effects of the Mangekyo Sharingan"
"Great, then it's time to go to Konoha."
