Hopefully, we get more depth because this is the main problem with this manga, this dude just one day goes "lol lemme just cut off my adopted daughter's arm" for what? goofs and giggles? And this isn't even like Shun's situation, this guy is a grown adult and there's solid evidence against him, even if there wasn't, this happened in his house which should make this an open-and-shut investigation.
...Granted, I should be used to this already since every single antagonist is like this but this doesn't even feel like revenge porn anymore.
