Kawaki and Boruto lunged at each other, colliding hands, then began exchanging blows.
"You have no idea how long I've been waiting for an opportunity to kill you," Kawaki said
"I can say the same"
Boruto jumped on the wall of the arena, surprising everyone in the audience.
"He can walk on the wall"
"It's so amazing," Natsu commented excitedly,
"I want that too."
Kawaki also ran up the wall trying to attack Boruto, the blonde easily blocked and dodged his blows, at one point Boruto grabbed Kawaki's shirts and jumped off the arena with him, hitting Kawaki on the ground creating a crater in it. Kawaki quickly stood up and made the seals
"Katon: Taredan!" He shot fire spirals into his mouth
Boruto jumped aside, also making the seals "Raiton: Shurakiri" placing his hands on the ground, the blonde released a stream of lightning that rushed towards Kawaki
Kawaki was forced to jump up to avoid Boruto's attack, suddenly the blond guy appeared behind Kawaki in a fraction of a second.
"What, when he..." Kawaki didn't have time to react because he received a powerful blow to the face from Boruto, which knocked him to the ground.
"Enough of this childishness, we're fighting seriously." Kawaki activated his Karma and Isshiki's doujutsu.
"I agree with you here," Boruto activated his Karma and Jougan
"What are these signs and those strange eyes?" Erza commented
"I have no idea, this is the first time I see something like this," Makarov said
"They look so cool," Natsu said
Kawaki shot some black rods at his brother, Boruto grabbed one of his rods and deflected the rest. Kawaki took advantage of this moment to approach Boruto and, modifying his arm, attacked him. The blond man blocked his stepbrother's attack with his hand, then kicked Kawaki in the stomach to the other end of the arena hitting the wall.
"H...how is it possible that he is so strong?"
"The roles have been reversed, Kawaki. I wish you hadn't even trained these years, I trained hard every day these years, even in handling Karma. The abyss still separates us, but we have switched places"
"Shut up!" Kawaki created several huge cubes above the arena and dropped them on Boruto
"What's that power?"
"These two must be at the level of a holy mage"
"No, they are certainly much more powerful"
Natsu had flames in his eyes seeing the fight, he also wanted to fight them. Boruto ran towards Kawaki, being so fast that the cubes fell down behind him. In a split second, he appeared in front of his brother and punched Kawaki in the face, sending him flying for a long distance.
"If I can't defeat you, I'll send you to the seventh"
"That's what I was waiting for"
When Kawaki opened the portal, Boruto saw Naruto and Hinata with his Jougan and managed to bring them outside.
"Damn!"
"Kage Bushin No Jutsu! Take my parents to the medical room"
The Boruto clones nodded and carried Naruto and Hinata to the medical room.
"I didn't think it would come to this, but you leave me no other choice, Boruto" Kawaki pulled out something resembling a chakra fruit
Boruto's eyes widened seeing this "This is..."
"You didn't think I didn't have an ace up my sleeve" after eating the chakra fruit, a strong earthquake was created and Kawaki's power increased several times
