Earthquake

Fortunately for them, the class was being taught by Tank, who was overjoyed to have new students to teach in his class, even if it was a Lightning Cerro.

"Come on over and join the Earthquake group. I know the skill as well, so if Thor encounters any issues, just ask me. But the ones here are all getting pretty good at it, even though it's a very advanced skill, so it shouldn't be difficult to learn from them.

Just remember that they are berserkers, so try not to get in the way of their training." The massive professor instructed.

"Got it. I'm sure that Thor will be fine, he's always been well-behaved." Karl agreed.

The berserkers gave the newcomers curious looks, as it was uncommon for anyone to visit their classes, and certainly not the juniors from other specialties, but when Thor was called out, they all changed from curious to bemused. 

The Cerro wanted to learn Earthquake? Alright then, let him try.
