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.
YMMV: The Kurosagi Corpse Delivery Service
Crosses the Line Twice: Only a series like this could have a romantic bonding scene with dead babies involved.
Nausea Fuel/Nightmare Fuel: Many chapters are loaded with material that will sicken and/or horrify, especially if you're sensitive to depictions of corpses in varying states of decay and the fauna that typically accompany corpses.
Squick: This series is rated 18+ for a good reason.
