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: The appearance of possessed!Kirari is pretty creepy and very sudden.
Shikanosuke's description of his panic attacks during his team on the tennis team get kind of freaky. Especially when he says that he "dreamed of thousands of caterpillars eating my body". Ew.
Not to mention the dream he has during Chie's route. Imagine all our hobbies are actually taking away our lifes the more we play/enjoy them. Example for Shika himself, his tennis racquet & his bass both sucking up his blood through a pipe connected to his heart!! Ugh...
