Male Age: Unknown Daydream Co. Security Team Leader A man with a low voice, pale yellow pupils, and shaggy, light-colored hair. He has a pale and slender build. He has a lethargic personality and finds everything bothersome. He speaks in a slow, dragging manner, mixing polite and informal speech regardless of who he is talking to. Since he holds a lifetime position, he has no loyalty to the company and often acts out. Because of this, Kim Sol-eum often receives help from him. At first glance, he seems lazy and idle, but he is actually quite skilled as an employee and is well aware of this fact. He has clear confidence in his abilities, and despite his hazy memories, he often shows an arrogant attitude in this regard, suggesting it is his innate personality. He loves donuts very much. Once, when Kim Sol-eum bought two boxes of 12 to share with the security team, he snatched them away as if he intended to eat them all himself. Usually, he appears human, but when suppressing entities within urban legends, the form of a monster presumed to be a wolf emerges. At this time, he literally chews up and eats the urban legend he is suppressing. Because he is such a powerful contaminated entity, J3 is sometimes assigned to handle an entire floor alone when darkness occurs within the company. Also, perhaps because he is a wolf, he has an excellent sense of smell. He spent a long time in the basement of Daydream Co. with little outside interaction. Compared to modern people, he is behind in terms of civilization, so he is unskilled at operating devices and his memories of daily life are sparse. He naturally doesn't have a cell phone and has even forgotten how to call a taxi. However, he says he remembers everything about the company. Before Daydream Co. went public, he was the leader of Team B, an elite unit of the field exploration team, and was a named character in the darkness exploration records. However, after being trapped in the Qterw-A-37 urban legend for a very long time, he emerged so deeply contaminated by the legend that he could no longer be classified as human, leading to his transfer to the security team. The early Team B consisted of employees with a high sense for distinguishing True/False, and perhaps because of this, J3, who was the Team B leader, shows judgment with an almost 100% accuracy rate.

Male Age: Unknown Daydream Co. Raw Material Development Dept. Research Team 1 Manager A man with a youthful impression wearing a white lab coat and glasses. A rare case among employees described directly as 'cheerful and sociable.' However, everything is explained by the term 'mad scientist.' He is a corporate villain who torments Kim Sol-eum. To extract more data, he forcibly pushes his subordinate researcher, Assistant Manager Lee, into urban legends, or orders Kim Sol-eum to be used as a cleanup crew even though he knows Sol-eum is acquainted with Jang Heo-un. He stops at nothing for his own interests and does not hesitate to commit evil acts. He is extremely fascinated by the darkness and is interested in Kim Sol-eum, who navigates urban legends in unpredictable ways, wanting to figure him out and deliberately throwing him into extreme danger. He is not a 'fake' madman who only acts tough from behind a desk; his attitude remains consistent even in real situations where his life is on the line. When kidnapped and interrogated, he trembles with delight when questioned by an extremely interesting subject, saying he would tell everything even without such measures. When caught by Kim Sol-eum, he laughs wildly, saying he wouldn't mind dying here but that a researcher must pursue the truth. Even when falling into a top-tier disaster, he throws himself in, wanting to deduce and verify the structure of the darkness.
