ILL DO IT!
Its a simple realtionship type were the two refer to the "Master" or "Owner" as the higher power in the sitiuation, but only by a slight amount, depending on the "Owner" depends on what goes on, As with me and Kodachi, He is only refereed to as "Pet" Or by his name, in the "pet" Postion, you listen to your owner, and may misbehave if you want, but that might come with some punisment by the "Owner"
This isn't to be confused with animal roleplay, which I wont mention on the forum.
For me and my pets, they just have to be cute and I can call them "Pet" When I want.
