Margaret is the assistant of Professor Mayzel, a researcher affiliated with the ARCAM Corporation. Both she and Mayzel were recruited by ARCAM to work on the development of Omihalcon-enhanced devices, notably the Armored Muscle Suit. Her role in the story is primarily that of a support figure, aiding Mayzel in his research and field missions concerning ancient out-of-place artifacts. In later parts of the narrative, she is deployed alongside Mayzel to the South Pole as part of ARCAM's excavation efforts. Margaret is depicted as a competent and dedicated technical specialist, though her personality and inner motivations are not extensively elaborated in the available material. Her key professional relationship is with Professor Mayzel, with whom she has worked closely since joining the organization. She does not demonstrate supernatural combat abilities; her notable skills lie in her technical expertise with ARCAM's advanced equipment and her reliability as an assistant in high-stakes research operations. She appears in both the original manga and its anime adaptations, fulfilling a consistent, if understated, role within the ARCAM team.
