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: about the Running Gag of saying that Emeraldas is the dangerous twin and Maetel the harmless one when it's Maetel the one who blew up a planet because she was disgusted. Becomes Fridge Horror when you realizes that not only is the people who knows them best to make those remarks, but the twins fully agree, making you wonder what the hell happened to consider a woman who destroyed a planet being harmless when compared to Emeraldas.
Hate Sink: The Prime Minister of Earth in the first TV series. Everything he says or does is designed to make the audience want to punch him in the face.
The Woobie: Mayu in the first series. The television show takes a perverse pleasure in torturing the seven year old girl in increasingly horrible ways. She's never actually abused, but has her pet bird eaten by a hawk. Gets attacked by wolves (!?). She even is forced to clean a church by herself with water dragged from a nearby stream.
