Yeah, I 100% understand wanting to skip cutscenes. Even for regular gamers.
Daanya's complaint about the economy is valid. Flooding the market with that much valuable ore would likely cause a problem.
Daanya is turbo pissed! She is a princess, and should logically be part of the government. Biting Shachiku in the head is probably the most severe punishment she can mete out for such economic manipulation.
That said, I think the author made a mistake. When a cat bites a human or an animal, their tail is often wagging, sometimes quickly. If a cat's tail is standing straight up, that usually means they are not hostile.
