Codename of a member of the A-class intelligence team. While his name is not revealed, his boss used to refer to him as "Shannon". Shadow dresses like a college student and his hair is blonde with a shoulder-length hairstyle. His personality is quite sociable, cheerful and friendly. Shadow also has a yellow car of his own. Shadow usually spends the night, so he has to have snacks with him most of the time. There was one time[1] he cried because he didn't have a drink at night. Fond of Pepsi, he also said that even his mother drank Pepsi instead of water. He helps Candy (Shihyeon) in almost every mission. Once, Shadow accidentally ran into a man on the road towards Shihyeon's place. Shadow suggests to Candy (Shihyeon) that they should move to another location for the briefing. Recently, he and Shihyeon, Hajun and Adam were sheltering on an island. Seemingly wanted, (as seen when he and his boss were on the phone in episode 87) before concluding the conversation with the boss, he said that he would bring back something he was pleased with.
