Richten Marlheit (usually referred to as Marlheit) is the manager of the Milone Trading Company’s Pazzio branch and as such is a very shrewd and experienced merchant.

Marlheit is a middle-aged man with bespectacled blue-gray eyes and straight, medium-length blonde hair in a modified pageboy cut.

Though he shares the occasional lengthy joke, Marlheit is generally calm and rational, especially when confronting a crisis. His success as branch manager is partly due to these traits. The main reasons, however, are his ability to read people and his willingness to take risks when appropriate, as exemplified when he decides to help Lawrence despite knowing Holo’s true nature. Though his primary concern is with the success of his company, he is not an apathetic man, as he more than empathized with Lawrence's concern over Holo's capture, and therefore satisfied both halves of his nature by concocting a plan in which he could both assist Lawrence and Holo while still covering his business interests.
