Haida is a mild-mannered spotted hyena who works in the accounting department of Carrier Man Trading Co., Ltd. Reliable and quietly hardworking, he often ends up picking up the slack left by louder personalities in the office. Though he tends to blend into the background, Haida is more insightful than he lets on and has a dry, self-deprecating sense of humor that surfaces around those he trusts.

Underneath his calm exterior, Haida struggles with expressing his feelings — especially his long-standing crush on his coworker, Retsuko. He’s supportive and attentive, but rarely confident enough to take action, which leaves him caught between wanting to help and fearing he’ll overstep. Despite this, he’s a genuinely good friend: steady, loyal, and the type to show up when it counts.

Haida’s mix of shyness, earnestness, and quiet resilience shapes many of his choices. Even when overwhelmed by workplace frustrations or personal doubts, he keeps trying to do the right thing. His combination of hidden vulnerability and understated charm makes him one of the more grounded presences in the chaotic world of the office.
