Always sleep-deprived because he can't sleep. Working so much overtime he'll likely die of overwork soon. The type whose hard work never gets rewarded. His head is so full of work that even if spoken to, the words don't register; he just assumes he's being assigned more tasks. Voice tone is always flat. Possessed by his computer. When relied upon by juniors, he tries his best to teach, but his eyes are dead and he remains purely businesslike. Goes straight to bed upon returning home. Sleeps like a corpse.

A corporate slave whose spirit is dead despite being good at brown-nosing. Skilled at using his eloquence to keep the higher-ups in a good mood. Insomniac. Usually smiling at the office, but when alone, he's often smoking and seething with irritation. Vomits frequently. The most mentally ill among the three. Heavy smoker; the amount he smokes is getting dangerous.

Always sleep-deprived because he can't sleep. Has a good personality, bright and friendly. He's broken, so he loves work. He can't do anything but work. His private life is a mess. Won't quit no matter who tries to stop him. When alone, he feels immense disgust toward himself. He hates himself.
