Perhaps...There's Fang, Shiro, and Marisa from vampire. Nokoto, Jin, and Faust from human...Amelia and Pewita from angels...Bernkastel and Paris from demons. So, either a guard, or Pewita. But then again, guard sounds better. If he attacks someone there, he'll be killed by everyone else, or shot by a few guards. Maybe he can make the excuse that he needs to use the washroom, takes a guard with him, and murderes that guard.
