The Nine Tailed Fox is a very powerful monster and his speed is pretty good. Inu No Taisho is also a quick fighter, but I think he lacks the Nine Tailed Fox’s intense energy abilities. One good blast it enough to take many fighters down for good. I don’t doubt that Inu No Taisho could match many of his feats, but he wouldn’t be able to keep up with him forever. Nine Tailed Fox wins.
