"Asshole characters are not interesting"

In my experience, asshole characters are the MOST interesting. Without asshole characters, character development, at least in my experience, is rather boring. If you don't think SkrubLord will fit in, then look at Ostarion. They would probably "get along". There's some ties between Saeraeka and Eeidos that would cause them to agree with one another. Remember, the teachers probably aren't chosen for their attitude, or anything other than their skill.

EDIT: I think you're the only one who would not want to write with him.
