Boruto and Kawaki flew out of the city and then faced each other.
"I think we've flown far enough, prepare for your end." Kawaki activated Isshiki's doujutsu and sent several black rods at his brother.
Boruto easily dodged the rods, Kawaki seized the opportunity and ran towards his brother to attack him. Boruto managed to block Kawaki's attack, then threw his brother away. This time, the blond attacked and instantly appeared in front of Kawaki. Before he could do anything, he was punched in the stomach by Boruto. Kawaki spat blood, but Boruto wasn't about to give him time to attack and kicked Kawaki in the chin, sending him flying.
"Kage Bushin No Jutsu!" Boruto created several clones, finishing Kawaki off, while the real one teleported in front of him with a Rasengan in hand. "RASENGAN!"
Kawaki couldn't react and was hit squarely in the stomach, knocking him to the ground.
Meanwhile, the bell for breakfast at Kuoh Academy rang, and the ORC group decided to meet up to eat breakfast together. Sona and Tsubaki joined them.
"What do you mean Boruto left and didn't come back?" Rias asked.
"He told the teacher he was supposed to be going to the bathroom. But he didn't come back for quite a while, so I went to check on him, and I didn't find him," Issei replied.
"Was he acting suspiciously?" Sona asked.
"He looked nervous."
"I'll send my familiar to search Kuoh and the area around town. After class, we'll go investigate his behavior," Rias announced.
"Hai."
At the same time, Kawaki began to rise from the ground, immediately activating the second level of Karma.
"You've really gotten stronger, Boruto. I think we should stop warming up and start fighting seriously."
Kawaki launched an attack at Boruto, this time much faster. The Hokage's son was forced to dodge the blows, at one point Kawaki kicked Boruto in the ribs and sent him flying.
"Damn!"
Suddenly, a huge cube appeared above Boruto, which Kawaki dropped on him.
"DIE, BORUTO!"
At the last moment, Boruto teleported to a safe distance. "It should be ready." The blond canceled one of the clones, which was gathering nature energy, thus entering Sage Mode.
Boruto ran towards Kawaki, who had no intention of letting him get close and began firing energy bolts. In the blink of an eye, Boruto appeared in front of his brother, trying to hit him. Unfortunately, Kawaki blocked the blond's blow.
"You think you can defeat me with tricks like that?"
Suddenly, a second Boruto appeared behind Kawaki. The older teenager didn't have time to fully turn before he received a punch in the face from Boruto's clone, knocking him to the ground.
"You were so focused on me that you forgot about my previously created clones."
"Damn you. When I'm done with you, I'll do the same to the shinobi world." Kawaki stood up and began unleashing his Otsutsuki power, causing the entire area to shake with its power.
Kawaki extended his hand toward Boruto, preparing to attack, but suddenly a figure appeared in front of him and placed a hand on the teenager's stomach.
"You...What are you going to..." Kawaki didn't get to finish, as the figure released its chakra, causing a powerful explosion that threw Kawaki a considerable distance.
Boruto was surprised to see the newcomer.
"It's been a while, Onii-Chan"
"H...hima"
