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.
YMMV: Magical Drop
Fetish Fuel: quite a few of the female characters. Especially The World & The Empress.
Retroactive Recognition: This game was one of the first games Tony Taka, a famous eroge illustrator, worked as a character designer when he worked for Data East before going bankrupt.
Viewer Gender Confusion: Yup, Strength looks and acts like a boy in Magical Drop III but is a young girl.
