It is a deal
Apparently, Chloe's behavior only changed since her defeat. Although she seemed to look cold and calculative, she lost a lot of friends in that battle a week ago. After the loss, she decided to focus on herself instead of getting close to others again. It was a backstory similar to Ryan. The only difference was that Ryan worked alone almost every single time.
"I have been training to have my rematch, but as expected, I won't have time for that," Chloe said. "It would be too convenient if we could train forever while that fucker's level only increases once every five days."
Based on the few seconds of fight he saw, Ryan concluded that those Berserk Lionel had some certain level of intelligence, but much like the demons, the creatures that spawned were just the minions of someone much smarter and stronger.
"This bad news made me depressed," Chloe said and then sighed. "You can take my place if you want."
