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.
Fridge Horror: All of the Hinamizawa Gaming Club, minus Rena and possibly Hanyuu, are dead.
Jossed: Makoto Itou's father is depicted as a doctor who cheated on his wife and left her for another nurse. Makoto's actual father in the game is much worse...
What an Idiot: In an effort to stop the Weather Dopant, and ignoring Philip's warnings, Keitaro attempted to use the infamous Twin Maximum Drive which, of course, fails and puts both of them under a week long coma. Haruka wasn't all too happy about it.
