"Exploding things? sounds interesting. And come to think of it... rather dangerous... like punching a person can make them salsa..." Pointed out Mika to aiden, then looked at Silvi. "And sure... when you move slow like me.. kinda get used to having to take a punch till you can predict things... so you learn to use your aura well. Don't even think about it most of the time now.." she explained and bundled the scarf tighter around her neck, enjoying the warmth it brought her. 

The day would go by easily, classes being introductory ones, unfortunately, moose had some homework for them, explain their takes on semblence and aura and what they think they're relevant to as your person. Bob gave basic maintenance lessons to them and started going into WAY too much detail about where the origins of dust fueled weapons came from, tangenting off into way too specific details and histories of key figures and so forth... The twins went about criticizing fighting styles. Mika got too comfortable in adjusting to one speed of fighting and couldn't handle people who changed pace, silvi didn't have quite enough foresight for the twin's liking and Aiden didn't act decisively enough, leaving time for his teammates to get overwhelmed by the twins. They didn't fault them as they were kids, but approached them as areas for improvement, still with the twin speak. 

A week would go by without much in the way of interesting things happening, till the next friday, a new arrival to the school, another teacher. A Biologist, but not for humans, for Grimm. 
Sitting in the class, the kids watched the tall and lanky man, skinny and limbs looking a little bit too long for the torso he had. "Good Day children, I'm Professor Dawn, Grimm Biologist. My Apologies for being late, my boat was caught in a storm for the duration, we had to make island fall till the grimm and the storm went away. We are lucky to be on the island, for it has unique properties such as the semi active volcano, allowing us to travel back in time and experience some of the early grimm who were turned to stone and not dissolved like they usually do." said the pale man, looking even more like a ghost than Mika did, and she was pale to begin with.
