A little AU thing I did a while ago. These three are prodigy students of Harmonia University on Tumblr! The trio only attend classes they're excel in. Oaken is a math specialist, specifically algebra. And Mouse and Grey are Battling students. After their classes, they go back to their dorms to study middle school level classes online. Mouse is very quiet and barely speaks, and when they do, it's low mumbling. But most of the time, they use sign language to communicate, or their hilt friend, Elizabeth. Grey is very protective over his friend Mouse, the two are almost never apart. Oaken attends different classes than his two friends, but still hangs out with them. He's not very talkative but he's very friendly.
