Since They Benefit Dark World Rulers Such As The Chaos King And The Queen (whom Rouxls Wants To Serve) - Tumblr Posts

Something I realized about Rouxls is that he's obsessed with being a servant and also a darkner, so you'd think he'd be ecstatic about helping out Kris and company ... instead he's very determined to serve other darkners.

I get him fighting against you in chapter 1, but there isn't any reason for him to do it in chapter 2. Like he's even dissatisfied and unhappy with Castle Town to the point of leaving it for another dark world.
