But, that is something that was never confirmed. People love jumping to conclusions. If I remember correctly, what Kawaki actually said was “I’ll send you to the same place as the Seventh Hokage, Boruto”, which leaves Naruto’s fate as ambiguous. He could be alive, he could be dead. But, I think if Naruto had died, he would just say so. The fact is that the Boruto series isn’t just about the Shinobi anymore. From the moment when Naruto reached the final arc, the story has changed its focus. We don’t just focus on Shinobi enemies now. The bigger problem is the aliens, the Otsutsuki. Let me back it up. After Kaguya came, the next person to cause problems was Toneri, who was an Otsutsuki. After that, the Gozu Tennou incident took place, which was again, linked to a different dimension, and the Otsutsuki clan. Later, we got the invasion of Kinshiki Otsutsuki, and Momoshiki Otsutsuki, and again, they were not Shinobi. Boruto himself has some sort of connection to the Otsutsuki clan. It is not absurd to believe that Kawaki, too might have some sort of connection to the Otsutsuki clan. That only means one thing, and that is, Kawaki has somehow, sent Naruto Uzumaki to a different dimension. The Gozu Tennou linked to a different dimension. Momoshiki confirmed the Otsutsuki travel from dimension to dimension. Kawaki has the Curse Mark, that is, the power of the Otsutsuki. It all adds up. Kawaki sent Naruto to a different dimension, and the reason Sasuke is not around is that he went to retrieve Naruto, as he is the only person who can do so with his Rinnegan. But, these are my thoughts on the situation. Do you think Naruto Uzumaki is dead?

This is why Naruto Uzumaki is not dead in Boruto  - 19
