I fucking love this so far, holy shit! I never knew I wanted a fighting game manga with fighting game mechanics / inputs in it before, till now lol. Again, my knowledge of Iori's original move set is a bit skewed, since I know him mostly from this old defunct Korean MMO, Lost Saga(RIP), but I know he has those ground fire projectiles, some kind of rush in into combo that might end in an explosion? That might have been Kyo's armor skill now that I think about it. . . . Either way, I know he's got that flaming uppercut we saw in chapter 1, and like some kinda cool flaming stomp.
Either way, seeing two projectiles clash is hype as fuck, lol. Must be hype for the spectators of the tournament too. Hope we see more moves next chapter!
