Martin Liebert is a minor character in the anime Spice and Wolf. He works as a business employee for the merchant Hans Remerio. Liebert is a middle‑aged man around thirty years old, with short blonde hair and a matching goatee. He is commonly seen wearing a black cloak over his work attire, along with a dark beret. His personality is not extensively detailed, but he is shown to be extremely tense and nervous when assisting the protagonist, Kraft Lawrence, in a high‑risk gold smuggling job for Hans. This suggests that Liebert is cautious and perhaps unaccustomed to or uncomfortable with illicit schemes, though his loyalty to his employer motivates him to follow through. His role in the story is limited to this single job; he serves as a contact and helper for Lawrence during that episode, providing minimal direct interaction with other characters beyond Lawrence and Hans. There is no significant character development or notable abilities associated with him, as he appears only briefly and does not return in later story arcs. His motivations are tied to his employment: he carries out his duties for Hans despite the apparent stress.
