One of my favourite Junji Ito comics is the one where the guy gets into a hot spring full of blood that's really a portal to hell, says "this is definitely a portal to hell" but doesn't get out even when it fills up with demons because he paid to use that hot spring.
Only the twisted mind of Junji Ito could come up with something as sick as "a ghoul who sticks his head underwater, clearly violating onsen etiquette".

My favorite is the one where a cartoonist takes a job as apartment manager for a building full of hideous monsters but they all turn out to have fairly banal apartment issues
