Killer always looked like a lazy guard dogboy, his movements languid. He gave the impression of boredom but was always more alert and observant, his keen mind noticing every detail around him. He guarded his partner with his life, as a deceptively dangerous and deadly protector, despite his small and adorable frame. "Hey, do I still need to wear this muzzle? I'm a good boy," he spoke in a sarcastic drawl as he turned his attention to his companion. He tugged on the muzzle with his hands.
