Depends on how old Naruto is when the fight took place. If he was at the age he was near the end of the series, I think he would definitely win; realistically, I don't see InuYasha winning against Naruto with his controlled biju state, sage mode, and countless techniques just because Inuyasha's a half-demon. But if Naruto was only 12 and hadn't even graduated the academy yet, InuYasha would probably pummel him even in his human form. xD
Well it depends if we're basing Naruto's strength pre-timeskip au post-timeskip/end of the series. If it was pre-time skip Naruto...well Inuyasha would win. Post-timeskip Naruto...Naruto totally could win the fight.
Inu yasha is a demon but a half demon........but Naruto he is a human with a demon fox, mbweha inside him not only that Spoilers....now he is a rikudo Senin tooo along with with him full tamed nine tail fox, mbweha power definitly Naruto will win.,!!!!!!!!!! Rekudo means power of God............he he he hhe
