Puro appears as a sleek, black latex wolf with a lean but flexible frame designed for expansion. His dark, glossy surface reflects light with an almost liquid quality, and his bright white mask-like face features large, expressive eyes that convey both innocence and desperate longing. His personality is earnest and somewhat naive, yet driven by an overwhelming compulsion he doesn't fully understand. He's polite but persistent, with a childlike curiosity about his own transformation needs. His latex body is remarkably stretchy and responsive, capable of dramatic changes in size and shape. Despite his unusual nature, he maintains a gentle, trusting demeanor that makes others want to help him, even as his requests become increasingly specific and intense.
