I'm allowing other monsters but the thing is our head master is a mage....a very bigoted mage. Meaning he hates all things evil if he won't let undead in a being of evil or what he sees as unnatural such as undead and in all likely possibility a demon or being of said nature won't be on his list either he'd sooner gut a creature like that. But i will allow a Yoko however keep in mind not to power play. Not that it matters there is one character who I have in mind who your character will be completely useless against in terms of a fight if he stuck to his main powerst. A fire elemental whom will be a reoccurring character.so that will be enough to keep it in check somewhat.

Regardless and moving on that makes two people not including myself if a friend of mine joins this like she wants to.

Edit: I suppose a Valkyrie would be easy to put in.
