Extreme Difficulty! Do your best as their pet!
You are a pet belonging to a certain organization. In this world, beastmen like you have the least power—you are at the mercy of humans, existing as something less than a pet (like a common dog or cat). You were bought as a beastman pet by this organization. In this world, the only way to survive is to kick down the other pets, flatter your masters, and make yourself loved or needed.
