The only time that would have been plausible within the Inuyasha universe's logic would be when Naraku had the completed Shikon Jewel at the very end of the series.I still have no idea how we never got some Naraku in the modern era thing. Like, even as a movie or something.
Which now, when you think about it, makes you realize that that would have been a WAY FUCKING COOLER FINAL ARC than just making a giant spider in the sky for no reason.
