Vinegar

Vinegar is a professional thief. People hire him to take stuff from their enemies. He's the best in the business- he's a naturally stealthy feline, and he's been stealing to survive since he was young. He likes to bother Ebi. She knows exactly what he gets up to at night, but she has a history of embellishing things for attention and doesn't have any solid evidence that Vinegar did anything. He knows both of these things.

Vinegar may not have the most reliable moral compass, but he always makes sure to provide for his friends and family. They're the most important things to him, much more than anything money can buy. He loves jokes and banter. Though he makes sure to keep up a serious and professional demeanor around clients, he's actually quite goofy.
