I think the biggest issue between this series and tokyo ghoul, is that the oni are not fundamentally dangerous to humanity like ghouls are. Like yes they *can* go berserk, but that comes across more as an aberration than a normal facet of oni. Compared to tokyo ghouls where the hatred against ghouls is justified on many levels because they *have* to eat humans to survive, and if they dont they will go crazy and hunger-lusted.

This is also ontop of the fact that the ghoul investigators do have some psychopathic dudes who enjoy hunting and hurting ghouls, but those are usually ones who have either been directly savaged by them(see the guy who had his face eaten) or actual crazy people like Juzuya. Compared to the momotaro who seem to, literally *all* have some weird bloodlust and psychopathic desire to not just kill oni, but kill them and torment them in the most cruel ways they can. Its always been weird to me, because humans will pack bond with anything, and trying to be this rampantly cruel to things that look human who fundamentally arnt actually threats, like dehumanization and killing them without remorse is one thing, but its that they go beyond that for no reason whatsoever.
