Chief, formally the chief clerk, functions as the male authority figure within the Popuu toy company office. Holding a supervisory position, he enforces workplace rules and addresses employee misconduct. His primary interactions involve reprimanding staff for errors or policy violations, often reacting with visible frustration and delivering extended lectures when standards lapse.

He maintains traditional expectations for workplace conduct, emphasizing orderliness and proper use of company resources. He directly confronts Yutori Tanaka about using office computers for personal homework and criticizes the disorganized state of her workspace, demanding immediate tidiness. His strict adherence to protocol clashes with Yutori's unconventional methods, particularly when her decorative desk modifications inadvertently inspire a profitable product idea approved by the section chief, leaving the chief clerk visibly surprised.

Significant tension defines his professional relationship with Reiko Dankai, especially when her dissatisfaction arises from errors in his written work. Despite his higher rank, Dankai openly criticizes his mistakes during confrontations, indicating his authority is not absolute. He becomes the subject of workplace gossip among subordinates, who advise avoiding engagement during his reprimands and waiting for his anger to subside.

Physical appearance details include a noted tendency for his wig to shift position during intense emotional outbursts, an observation that distracts Yutori internally during his lectures. Documented information covers only these workplace interactions, with no personal background, full name, or further character development provided.
