Yataro watched the situation from hiding, Mirika approached the unconscious Sarada and Mitsuki and activated one of her devilish abilities.
"What are you doing?" Sayori asked
"I'm going to bring these two back to normal," the redhead replied
A red circle appeared beneath Sarada and Mitsuki, then their bodies began to glow. At that time, Boruto and Kawaki rushed at each other, starting with the exchange of blows, Kawaki tried to attack the blonde, but Boruto blocked perfectly and sometimes avoided his blows, when he wanted to counterattack, Kawaki blocked his blows, after a momentary exchange of blows, they both jumped away from each other. Kawaki joined his hands, after a while strange black circles appeared around Boruto.
"What is this?"
Kawaki said nothing, but sent them to Uzumaki, in response to his attack, Boruto created several clones with which he covered himself when the circles hit them and caused a large explosion.
"What an amazing attack."
Kawaki immediately appeared behind Boruto, putting his hand to his back, and he released lightning from it, shocking his foster brother with it. "That's the end of Boruto."
When Kawaki was about to bend down to finish the blonde, he unexpectedly hit him on the chin, knocking him into the air
"Kage Bushin No Jutsu!" Boruto created two clones, then jumped upwards, then the clones released air from their hands, then pressed them against the feet of the original sending it flying with an amazing spine. "Boruto stream!"
Kawaki did not even have time to react, when Boruto punched him in the stomach, causing the black-haired man to spit some blood, and then they both fell to the ground.
"What is Kawaki, you're just gonna lose, let's show him our strength." said a strangely familiar voice
When Kawaki opened his eyes, the proteins turned black and the pupils were blood red, black rims appeared around the eyes and a dark aura surrounded the body.
"What is this power? Wait, this aura is similar to that of Yataro, that is, Kawaki possessed demonic power" - thought Boruto
Kawaki disappeared from Boruto's sight, then in a split second appeared next to him, Boruto tried to raise his guard, but Kawaki was faster and kicked Boruto into the stomach into a nearby lake, then Kawaki flew into the air creating purple lightning balls in both hands, then he joined them together with his wrists, causing the spheres to turn into a dragon's mouth.
"Raiton: Ryuunizari!" a ray of lightning shot in the shape of a dragon.
When the attack hit the lake, it created a powerful explosion, destroying it.
"Boruto!" Sayori screamed in horror
"Damn, what an amazing attack," Mirika thought
At this point, Sarada and Mitsuki regained consciousness "What's going on, who are you?"
When Mirika introduced herself and explained the situation, Boruto was hiding behind one of the trees, panting heavily, his sweatshirt was completely damaged and his shirt was half torn off.
"Shit, he's really trying to kill me. What to do, what to do, even with Karma, I cannot defeat him when he uses this demonic power." he thought
Suddenly Kawaki appeared in front of Boruto grabbing him by the neck and lifting him up.
"I found you, I hope you enjoyed the last moments of your life properly, because this is the end" he said, squeezing Boruto's necks
Suddenly the blonde's body was surrounded by a blue aura, a strange horn grew from his forehead, when he opened his right eye, Byakugan appeared.
"I won't let my container be killed," said a new voice, which was mingled with Boruto's voice
