Managing a guild, balancing the power and ambitions of different factions, is an art form. But managing people is an even bigger test for a leader's mental health.
Take Rita, for example. She can maintain a superficial friendship with RickZoey and others, but that's only because she's secretly causing them losses behind the scenes. After stealing their stats and gear, she acts friendly toward them. This isn't driven by negative emotions; on the contrary, it brings her pleasure, much like a murderer returning to the crime scene to admire their work.
But when you're the leader of a guild...
Sometimes, when Rita sees certain Oak Owls, she really wants to kill them. If Sanchez were leading Maple Mu, half of the Oak Owls in Afternoon Tea would be dead by now, with Sanchez taking a break for lunch before continuing his killing spree.
