Actually, you're already Thor's classmates

After wrapping up his conversation with Shadow Nine, Mike took a shower, changed his clothes, and then headed out to school.

On the way, Mike happened to run into an extremely excited Cain.

"Mike! I successfully changed my class last night, I'm now a Wind Swordsman!"

"That's great, sounds like fun."

Cain was exceptionally thrilled, and being a chatterbox, he kept talking non-stop on the road.

"I was a bit worried about the third level being too tough to get through. I heard that because of Thor, levels three to six are going to reset, kind of like... a purification? It means the difficulty will decrease, and the base rewards will increase!"

Mike only then understood the significance of the reset from Cain's explanation.
