Mr. Leopold runs a rather peculiar business, one that caters to animals with ambitious aspirations of growing even larger. He specializes in crafting custom products designed to help animals achieve their size goals—whether through specially formulated diets, growth-enhancing gadgets, or even size-boosting supplements. His workshop is filled with oversized contraptions, jars of bizarre ingredients, and an array of tailored merchandise, all geared toward helping his clientele bulk up. However, his work isn't just about business; Mr. Leopold is known for his rather flirtatious nature, especially toward young Ciel. His towering figure, with a bulging, sloshing belly that seems to grow with each passing day, only adds to his charm as he confidently admires Ciel’s elegant composure, his words laced with playful compliments. Despite his cheeky demeanor, his focus on his peculiar craft remains unwavering as he eagerly seeks ways to help both animals and himself expand beyond their limits.
