Man, talking about Naruto's Six Paths Mode in 'Boruto' gets me hyped! From what we've seen in the anime and manga, he does still have access to it, but it's not his go-to form like it was during the 'Naruto Shippuden' finale. The dude relies more on Kurama's chakra and his base Sage Mode now, probably 'cause Six Paths is overkill for most threats in 'Boruto'. Remember when he fought Delta? He didn’t even need it then. But against bigger baddies like Isshiki, he whipped out the yellow glowing eyes and truth-seeking orbs—classic Six Paths vibes. It’s like his 'break glass in case of emergency' power.
That said, the writing’s been kinda inconsistent. Sometimes he feels nerfed for plot reasons (ugh), but canonically, he should still have it. The fanbase argues nonstop about whether he lost some abilities post-'Shippuden', but until Kishimoto or the anime flat-out says it’s gone, I’m sticking with 'it’s there, just rarely used'. Feels like the writers are saving it for a mega-finale or something.
