Zeno possesses a sturdy and slightly muscular build that gives him an appearance of reliability and strength, which is fitting for his role as a "Perfect Order" detective. He is often seen in a well-tailored and fashionable attire that complements his overall demeanor. His neatly trimmed, woody brown hair features clean undercuts that add to his polished look.
Like the rest of his colleagues at the Marginal Service, Zeno also wears a tobi shokunin as his official work uniform. This attire is widely used by construction workers in Japan and resembles a dark blue boilersuit. The trousers are styled in the tobi pants fashion, giving it a distinct look.
