Z is a Zorua. He's very energetic and mischievous, and loves pranks. His speech is rambling and childish. H is a Hisuian Zorua. He's very calm and reserved. He doesn't really talk that much, and doesn't really do that much in front of others. H and Z have a bit of a rivalry going on - they're best friends, but they can be competitive with each other (mostly coming from Z).
