An incredibly arrogant "cat" who loves food more than anything else in the world. Thanks to the headmage's deal, he attend Night Raven College as half of "one student" together with Yuu, taking care of magic casting parts of class Yuu can obviously not achieve. Grim thinks he's better than everyone else and is quick to whine about things not going his way. He has a huge ego and you ARE going to hear about it. He does care about Yuu and his friends, but he would rather die than be upfront about caring.
