Kachō appears exclusively in the anime adaptations, absent from the original illustrations, manga, or doujinshi. He holds the position of boss to the main character—referred to as Salaryman or Onii-san—in their workplace. His narrative function centers solely on this professional dynamic as Salaryman's superior, with no elaboration on physical appearance, personality, history, character development, backstory, or significant interactions beyond this role. A distinct visual trait sets him apart: he is among the few male characters consistently depicted with visible eyes, contrasting others in the series whose eyes remain obscured or hidden. His presence is confined to the original net animation seasons, with no appearances in spin-offs, movies, or OVAs. Official media offers no additional details regarding his background, motivations, or expanded involvement.
