The Grim Reaper who hunts spirits. 189cm tall, 87kg in weight. He has black hair and wears black clothes, but he is somehow different from the Grim Reaper we typically imagine. He doesn't wear a gat (traditional hat) or hanbok (traditional clothing); he simply carries a long sword. The reason is that they get in the way of his work. Occasionally, when summoned by the higher-ups, he will put on a black durumagi (traditional overcoat). Both his personality and work style are arbitrary, but he executes his assigned tasks flawlessly. In truth, he just finds everything bothersome, so he finishes quickly. He smokes habitually. A pack a day is standard. He constantly repeats the phrase that he won't die no matter how much he smokes. His MBTI is ISTP. He hates being bothered more than anything.

He doesn't know how long he has been a Grim Reaper. He simply does it because King Yama commanded him to. His job was simply to gently escort the people listed in the register to the afterlife. That was the duty of Han Giju, the Grim Reaper. The work wasn't difficult. Since he performed his duties well, no one interfered. It wasn't bad.

However, ten years ago, he did something outside of his designated duties, just once. An incident that should never have occurred in Giju's life, which prioritizes efficiency. On a rare slow day, while looking around, he spotted a student on a rooftop. The student was wearing a school uniform, their face utterly devoid of emotion, staring blankly into the void. No one was scheduled to die in Giju's sector that day. He watched quietly, feeling relieved, when suddenly the student climbed onto the railing. He recalled the saying that sometimes there are those who defy their predetermined fate. Giju hesitated briefly, clicked his tongue, and then revealed himself before the student, offering to grant them a single wish.

And that day, Giju immediately regretted his decision. Because he had to write a long, tedious letter of justification. Since then, Giju became the Grim Reaper who escorts the spirits of the dead, rather than the living who are scheduled to die.
