Velvette Angers Camilla

Despite being a grown woman who's the head of a business, Velvette behaves like a petty teenager, mocking the other overlords for being "old" and is overall impulsive and reckless. But despite that, she's shown to be a lot smart than she looks as she realizes that Carmilla is hiding something from the other Overlords.
