Made in Abyss
The concept, music, and art are quite good.
But the amount of fetish the creator doesn't even hide, with underaged characters, fixating on one's genitals for a quick "tee-hee" moment throughout the entire show, body mutilation, constant depiction of vomit and piss, medicine unnecessarily made to be applied in a sexual manner. All that done in a cute art style was awfully jarring. Apparently the mangaka knows his fetish is showing and he don't care lol.
Also
"Tap Water Pollution" the webcomic.
