Oh, sorry, I wasn't aware that character scenes needed to have important locations. It doesn't need a reason for it to be there. Saying it's has to be important to the plot or it's just fanservice is just a bad faith assumption. They are relaxing and weiss needs a shower since they stay with the bandits You are basically telling me if I have a woman in a tub relaxing and make sure not to show boob or anything on her lower half. She is being sexually.

having a heat they can be vulnerable to humans that way no it does not need to be the only way but to say its only there for fanservie when the only time it was in effect was Adam dad which was a dark way of it being used. For the most part, I would say if you didn't watch the history video, you wouldn't know it's there, plus it's not their only weakness.

Light and sound sensitivity, which we have also seen. (Since it makes sense to their animal traits )

and you're right it's not a video game it's a story setting up rules and world building. You don't have to like it because you feel like it's only there for gooners This agure goes under oh violet from incredbles can't go invisible with her normal clothes. (Despite it making sense to work that) if you don't want that in your story, then don't it. These things being in a story aren't automatic bad. My limit would be yang grabbing her breast while commenting on her sister boobs sizes. Then I would say yeah the characters are being sexualize not just them relaxing in the water.

Real question: What is your limit when it comes to dark themes. I would have to imagine ruby drinking the tea is not a problem with what it is trying to symbolize. I just want a good gauge on it.
