Suggested by Sonic Kazuya has his demon mode which does amplify all of his stats, but I don’t think it will be quite enough to take down Kaguro. Kaguro was able to easily outspeed Gen and that kid was already quite fast. Kaguro’s attacks will also deal a lot of damage and while I don’t think his healing will be enough to outpace Kazuya’s attacks, they just won’t be hitting him often enough. Kaguro will be careful and he’ll chip away at Kazuya. Kaguro wins.
