Qontessah herself was a demoness and this didn't need to be told as just looking at her and those around her, Alita could sense that dark aura she knows a lot about.
There were also witches, immortals, vampires, werewolves, and many others. She was so surprised to see that there was simply too much and she felt very blessed to have met Ivy who only lusted for her body first and Qontessah who didn't mean any harm despite being stronger than her.
Alita listened to that soft voice as it narrated to her about this world and her back was already drenched with sweat. She had taken advantage of this world having thin spiritual energy and assumed that there weren't any powerful people.
But the knowledge of people especially these supernatural beings who didn't rely on any spiritual energy to survive, she realized that she was a fool and overestimated herself.
