Section Chief Moon heads the Product Planning Division at his fictional workplace. His round face evokes a full moon, and a unique visual trait depicts his face appearing on the back of his head whenever he dozes off at his desk. Moon routinely works excessive overtime, leading to prolonged absences from home that can last over a month. His personal living space suffers significant neglect during these periods, accumulating problematic levels of garbage. This personal disarray sharply contrasts with his professional conduct. Moon exhibits perfectionist tendencies in the office, compelled to clean immediately upon perceiving even minor untidiness. This cleaning compulsion often distracts him from his core responsibilities. A recurring preoccupation with nasal hair maintenance causes him ongoing concern. He communicates taciturnly, particularly with colleague Brown, relying primarily on gestures and expressions rather than words. Moon's established traits remain consistent throughout the series; his role centers on workplace scenarios highlighting corporate challenges without revealing personal history or undergoing significant development.
