Kadomon Risch is a fruit seller who runs a stall in the Royal Capital of Lugunica. He lives with his wife and daughter and is known for selling local fruits such as linga. He has a muscular build and green hair often tied back, sometimes with a twig held in his mouth, giving him a rough outward appearance. Despite this, he is a kind and good-natured person, though he can become irritated by the behavior of Subaru Natsuki when it occurs near his store. Kadomon is motivated by his work as a merchant and a desire to provide for and protect his family. In the story, he is one of the first residents Subaru encounters upon arriving in Lugunica, and his fruit stall serves an important role as a return-by-death checkpoint for Subaru during the first and third arcs, earning Kadomon the informal fan nickname Mister Save Point. His key relationship is with Subaru, who repeatedly visits his stall, and his family includes a wife and daughter. Kadomon does not experience significant personal development; he remains a consistent supporting figure representing everyday life in the capital. He possesses no magical or combat abilities, with his narrative significance deriving from his occupation and the location of his stall.
