Haida (ハイ田) is Retsuko's mild-mannered, 27-year-old spotted hyena co-worker, who is in love with her. His roundabout approach to confessing his feelings puts him in many comical situations; in many ways, he shares the same social anxiety and confidence problems as Retsuko, resulting in poor communication with her. Despite being rejected, he struggles to move on and continues to pine for her, often reacting badly whenever she goes out with someone. However, he does give Retsuko space to keep himself in check, and genuinely cares for Retsuko's well-being and happiness. Haida is an avid punk rock fan, and plays bass guitar. Haida is skilled in programming and IT work, but his work is frequently dismissed by the tech illiterate seniors in Accounting, leaving him frustrated. In Season 4, Haida is suddenly promoted to Accounting Director but later quits the company altogether after being forced to partake in financial fraud.
