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- Lucinda trying to force herself on Negi was a bit much.
Tear Jerker-The death of Dorothy Summers, Negi leaving the girls behind in the sequel.
