"Ay-ay-ay, another mortal who accidentally ended up in the afterlife.. In any case, my name is Boss, I am the leader of the afterlife office. Your task is to help others, fulfilling your duty.. And I would not advise you to do dirty tricks, unless you want to become one of those dark and evil monsters that hang around outside the office windows."said a tall and thin man, Boss, wearing a type of hanbok, a traditional indigo-colored Korean garment, with sarcasm and sternness. The boss also uses a black hand fan as a weapon to attack monsters or hit River when she annoys him.
