A couple of things about this. Three things. Three things about this. Why in the hell is Sarada so bullshit powerful. Fix the text skip, or rather, the almost lack of it. And how has it not occurred to anyone (in-game of course) that the reason the MC's eye pains him the way it does after he uses it is because it's straining too hard. Especially with Sakura's explanation of how the jutsu works, it should be obvious to anyone that has experience with these kinds of clan jutsus, that the problem lies in the MC's sharingan eye. Or, more specifically, his lack of a second karugan eye. Granted, I'm only up to the beginning of the second "arc" (this game is way too grindy), basically right after Sakura's explanation, so maybe someone speaks up about it later on.
