These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

Nightmare Fuel / Nausea Fuel: This being made by Hiromu Arakawa, there's scenes in labs involving images of flesh, organs, mutilations and whatever other horrible stuff that there are on experimentation on humans.
