Inui, as far as I know from his other games, doesn't show guro scenes, just gives you an hint to it, like in his last game, The Hounds of the Blade, where MC gets her stomach blown up by abnormal big fly maggots. The only thing you saw, was her stomach getting bigger than it could be and the screen turned red. Doubt he would go further in this game, let alone the rules in Japan are against depiction of explicit gore and violence such as gut or open wounds. That is why most open wounds in manga and anime are blacked out. I believe the only example I saw so far was Gantz, but maybe there are more out there.
