Marvin watched Kai through a small floating orb of fog that hung in the middle of the room with a small smile. He was happy with the different applications that Kai tried applying while maintaining an active aura. He had never thought Kai anything like that, or even remotely mentioned it even once.
"He's doing well, isn't he, Kasuyi?" Marvin turned to the man that was standing beside him. The two of them were currently standing at one of the many windows of the dark castle that overlooked the city below.
"He is. Not that I expected any less." Kasuyi shrugged as he swirled around his signature glass of wine. "He is y blood, after all."
"Don't think it's all your blood. I've put in a lot of good hours of hard work in order to build up his lacking foundation. His spell casting was basically nonsense, and his mana manipulation was shameful! If he was left to carry on like that, then he would have probably crashed into a barrier at the Sky Class!"
