Prologue

Boruto and Kawaki fought Code, who had absorbed the Juubi's power. Kawaki fired a chakra beam, Code blocked the attack without any problems, at the same moment Boruto appeared behind him.

 "What?"

 "It's over, Code!"  Boruto placed his hand on Code's back, a moment later his body began to fall apart.

 "Finally, Code has been defeated"

After Code was defeated, Kawaki appeared behind Boruto and pierced his body with his transformed hand.

 "Kawaki, you bastard..." Boruto coughed up blood

"Now that Code was killed, you were the only one standing in my way, Boruto" Kawaki held out his hand and watched as Boruto's body fell to the ground.

 "BORUTO!"

Sarada arrived at the scene, surprised to see Boruto dying.

 "You didn't need to come Sarada, I didn't want you to see my death..." Boruto said the last words before his eyes closed.

 "He finally died"

 "You will pay for this" Sarada activated her Mangekyo Sharingan and moved to attack Kawaki

 "Do you want to join him, I'll be happy to help you" Kawaki shot several black rods towards Sarada

Sarada activated Susanno, but the rods tore through it.

 "Damn it"

 "It's for nothing"

Sarada jumped onto the ruins of the palace, then created technique like a Chidori in her hand, before pointing her hand upwards, shooting a powerful stream of lightning.

There was a lot of lightning in the sky.

 "Raiton:Chidori Rizomari!"

The lightning combined to form one huge arrow, Sarada with a wave of her hand directed the lightning arrow at Kawaki, when the attack hit it caused a gigantic explosion that destroyed the area nearby for several dozen kilometers. After performing this attack, Sarada's Sharingan turned off and the kunoichi knelt on the ground.

 "I used almost all of my chakra for this attack..."

Suddenly Kawaki jumped out of the ground and grabbed Sarada by the neck "Pretty good attack, I think you could defeat more than one weak Otsutsuki with this attack, but not me. It's over, you can greet Boruto in the afterlife" Kawaki said and snapped Sarada's neck

After killing Boruto and Sarada, Kawaki released Naruto and Hinata from another dimension.

 "What happened...Boruto, Sarada!" 

 Naruto and Hinata immediately ran to the body of their son and Sarada "They are dead..."

 "I was the one who killed them, seventh"

Naruto looked at Kawaki with a cold look, without even waiting for his explanation, he immediately appeared in front of him "This was your last mistake, I was disappointed in you" said the Seventh Hokage, creating a Rasengan in his hand with the power of 8 bijuu

Kawaki didn't try to defend himself, Naruto easily killed him, destroying his body.

 "Naruto-kun, look!"  Hinata exclaimed

Toneri appeared on the scene with an Otsutsuki woman

 "Toneri, what brings you here?"

 "I'm going to bring these two back to life, but Boruto and Sarada will be reborn in a completely different world"

 "What, can't they really be revived here?" Hinata asked

 "Unfortunately, it's too late..."

 "I see"

Toneri walked up to Boruto and Sarada's bodies, sticking his hands out over them.

 "Boruto, you don't deserve this fate, I hope you will have a better ending in the other world"

The Otsutsuki woman placed her hand on Sarada's body "Sarada Uchiha, I am giving you some of Otsutsuki's power, good luck"

After a moment, Boruto and Sarada's bodies disappeared in a blaze of light.
