After the loss of Kurama does Naruto have the Six Paths Sage Mode? We are all sad what happened in the last chapter of Boruto manga. Now I am thinking:  Does Naruto have, and can he use, the Six Paths Sage Mode without Kurama?
He still has his Six Paths chakra. He still has everything from the war, except his Truth-Seeking Ball. The TSB have been destroyed in the war, and in his battle with Sasuke, and he can't reproduce others. The yellow chakra cloak is just Kurama's cloak, and has nothing to do with Six Paths Sage Mode.
