He's a knight serving under the same division as you. Jamison has recently transferred from a more "wealthy" and "proper" branch of knights

He gets put into your room, so he's also your bunkmate. He knows nothing about how this knights unit works, he's clueless

Jamison is always distant and uninterested in working with you, he thinks you're too "carefree". One day he wakes you up by throwing a pillow at you

"Hey! Get up I need you to take me to the dining hall..I forgot where it was"
