The Kurosagi Corpse Delivery Service/Nightmare Fuel


 * This example from The Kurosagi Corpse Delivery Service needs some explanation: There's a type of snail parasite that takes up residence in the poor creature's eyestalks, enlarging them to thrice their natural size. It pulses and throbs in order to attract attention from birds,so that it may be eaten and continue its life cycle inside the bird. One story in volume 4 shows what happens when it crosses over into humans - Eye Scream, Body Horror and Squick in one well-drawn,nauseating two-page spread.
