Ria

Ria (spelt Rhea in the English version) is Emiko's pet cat. Ria is very protective of Emiko and won't have anyone bullying her or her friends and always guards them, much like a dog. Warai often jokes that he expects her to bark anytime now.

Development
Well, she's one of the few characters not based on anyone.

Personality
Ria is a bold, brazen and protective cat and doesn't let anyone tease or bully Emiko. She acts rather like a guard dog, and is perfect proof that size doesn't matter. She enjoys drinking milk the most, but is occasionally seen eating fish.
