Luther Roosevelt is a supporting character in the anime The Tale of Outcasts. He is a contractor, a human who forms a pact with a demon, specifically Dantalion, one of the Thirteen Calamities of the Wasteland. This partnership grants him supernatural abilities and ties him to the conflict between humans and demons. Luther is a male adult with short blonde hair and a distinctive appearance that includes a facial scar and an eyepatch, often wearing a coat. His personality is characterized by a love for excitement and conflict; he openly wages war for the sheer pleasure of it, treating battles as entertainment. This thrill-seeking nature drives his actions, making him a volatile figure who engages with both demonic and human adversaries. In the story, Luther and Dantalion play a role in the larger struggle between the Order, an organization that hunts demons, and the demonic entities themselves. He is depicted as an antagonist or at least an opposing force, as seen when he and Dantalion arrive at the Order's headquarters, confronting the vice-commander without any intention of backing down. Key relationships include his demon partner Dantalion, as well as another demon named Sitri, whom he also commands in his campaigns. Luther's development remains limited in the anime; he is presented as a static character whose motivations center on personal amusement through warfare. His notable abilities stem from his contract with Dantalion, presumably granting him enhanced combat prowess and demonic powers, though the exact nature of these abilities is not extensively detailed.
