This sudden eagerness to learn from Michael shocked both Leo and Raphael. They knew Michael sucked at fighting, but they also knew he was a god. They never thought a god would willingly bow his head to learn like that.
"Hahaha, a god wants to learn from me? Then later when you become a god, I'll be a god's teacher, huh?"
Raphael burst out laughing. He wasn't happy because he got to act superior to a god, but because of Michael's current attitude.
At first he'd also thought about how to teach Michael, but he was a bit worried that a god's pride would make Michael stubborn and not listen.
Of course, he could use violence to solve this. But if he did that, it'd easily crack their relationship.
Leo had also thought about the same issue but didn't have a better way than Raphael. It could be said that Michael being this proactive made everyone feel way more comfortable.
