Oh, really! Gai makes a face right back! He does glance around the classroom though, ah, the feeling of a new school! Was that guy really supposed to be here, though? Sneakers... weird pants... t-shirt... totally not the image of a teacher at all! But he was sitting at the desk, so...

"Do you teach here?" This guy thought he was something, didn't he. The youth can't really do much about it either way, but he could at the very least give a hooligan a stern talking-to if need be--or guidance, since most lost souls also needed that! A hero to bring them back to light, as it were, and Gai could totally fancy himself as that sort of person.
