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: Kale. As a guinea pig. First he was transformed into a human, and then when he was beaten up, his repressed memory of him transforming into a fox tried to kill him in his dreams. Later, it's implied that unless they are able to erase this memory (fox Kale, or Fale) then he will have to be killed.
