I love the fact that only Junko's left eye (the one nearest to her father, and thus the one that is much more visible) has the yandere glow. So defensive of her boyfriend!
The best part of this is how it's basically the same for every father meeting their daughters boyfriend the first time even if the father is not a homicidal maniac.
Does the mother ever get mad that her daughters are stealing her cutlery or do they gift them their own sets? And, if the latter, why not customize them?
