[An overly friendly puppy. It's unfortunate that he's like this given he's supposed to be an attack breed of creature, but it's probably fine.]

Probably. She's also one of the most involved people in this school so it wouldn't surprise me if she's supposed to show you around during the afternoon. [He looks a little put-out about that, like maybe he's bummed he doesn't get to come along. Even while that's happening, his fur ripples back to something dark green with black spots instead.]

It's a camouflage technique! [He sounds proud at least.] It's supposed to help with blending in to sneak into enemy territory but the traditional colors are pretty boring. [And to prove his point, he waits before his fur becomes the color of the desk he's seated on.] I'm still working on combat.
