After a nap, Kai woke up with a fresh mind. He saw Arba sitting next to him while watching their surroundings.

"Mhm?" Kai yawned while stretching his body. It was a short nap, but it was certainly satisfying. "Sorry for making you wait, Arba."

"It's fine. I know that I pushed you too hard." Arba shook her head. "Besides, it's all good now. You have recovered your stamina and we are ready to start the next training."

"Indeed." Kai nodded in agreement.

"Though, your student sent you a message right after you fell asleep."

"Really?" Kai tilted his head innocently while finding a message from Felice. He opened it without hesitation, wondering what Felice had to say.

"Big Brother, do you remember the day you told me all your magic? I'm sure you remember. I am sending you this message to fulfill the second requirement to be your student and wish to learn something about this so-called magic further."
