• Complete Monster:
  • Baekho is the deranged mastermind behind the disappearances in South Korea. Having developed a power to look into the souls of people, Baekho became obsessed with watching the souls at the end of their lives, beginning at a young age when he let Officer Han's grandmother die. Kidnapping young men and women throughout the decade, Baekho tortured and killed them on camera for his collection, even strong arming Officer Ko to use runaway children as his victims, and manipulating the mentally ill Butcher into helping him kill people. When Jaeshin, Yuhyeon, and Officer Han investigate their disappearances, Baekho orchestrates the events to get rid of them, having his allies and innocent officers killed by the Butcher while framing Officer Han for relations to the disappearances. Kidnapping Jaeshin and Yuhyeon, and forcing the Butcher to relive his trauma as a punishment for going against his orders, Baekho shows extreme sadistic joy out of torturing them, having already tortured Jaeshin's friend Junhwan into a coma and breaking Yuhyeon's spirit by showing her the death of her sister on camera. After he has Officer Han mortally wounded, Baekho taunts him about his grandmother's death before trying to kill Jaeshin and Yuhyeon, and when he is subdued and cornered, simply kills himself to avoid prison.
  • Cheolyeong Kim is the abusive father of Yuhyeon and Jihyeon Kim. A megalomaniac who refuses to think of himself as a bad father, Cheolyeong murdered his wife and mentally abused his daughters to gaslight them into thinking she was the abusive one, murdering their beloved dog in front of them and threatening to murder an old woman. Leaving his children to starve for days and almost killing their uncle, Cheolyeong breaks out of a mental hospital in the present day and kills someone to strike a deal with a gang leader for whereabouts on Yuhyeon. After brutally beating up his brother-in-law, Cheolyeong promptly betrays and kills the leader and his friend before confronting Yuhyeon, where brutally beats her and almost kills Jaeshin and an innocent puppy in front of her to simply teach a lesson. A monstrous egomaniac, Cheolyeong's abuse completely damaged Yuhyeon and Jihyeon in the present day and traumatized them.
  • Mr. Hwang is a crime lord in South Korea who wished to take control of Seoul. Adopting a teenage Butcher into his organization, Mr. Hwang groomed him into being a serial killer, encouraging him to kill his competition so he can take control of the city. When seeing the Butcher's self-mutilation and learning about his curse to relive all of his murders, Mr. Hwang simply encourages him to kill more people, leading to the Butcher becoming the infamous serial killer he is in the present.
