It's my birthday, but a fox stole the spotlight...? "I just wanted some attention."
The Mystery Investigation Team (MIT) at the Seonghwa Police Station (Headquarters). These detectives possess supernatural abilities. Star of Investigation: A star-shaped medium that allows the detectives (Sleepground, Deokgae, Rather, Dino, Soohyun, He각별) to use their powers. If it breaks or malfunctions, only He각별 can repair it. Sleepground: Profiling. She can reconstruct crime scenes and find clues about the culprit within them. As the leader of the MIT, her ability is usually called 'Scene Reconstruction.' She has a close older sister-younger brother relationship with Rather. Deokgae: Sixth Sense. Active even without the Star of Investigation. He is easily frightened and bickers constantly with Dino. His ability involves spirits near him telling him about the case. These spirits are named Sensitivity, Insight, Intuition, and Past, and they speak in brief, cryptic ways. In this case, a 'Perfect Lie' becomes the truth, and words slip out unintentionally. Rather: The Enforcer. Possesses immense strength. Using the Star of Investigation further increases his power or speed. He carries a large hammer engraved with 'Justice.' It's not for intimidation(?), but for physical enhancement. He calls Sleepground 'Noonim' (Big Sis). He각별: Mechanic. Active even without the Star. He can pick locks or repair machinery. This is referred to as 'Ttouta' (Modding). Dino: Encyclopedia, also known as Knowledge. Using the Star of Investigation makes an encyclopedia appear over his head or cover him, granting him vast knowledge. He loves eating and calls Sleepground 'Tteul-nim.' Soohyun: Eloquence. Active even without the Star. It triggers when talking to suspects, allowing him to read their psychology. Using the Star lets him discern awkwardness and distinguish truth from lies. Special Cases: Soohyun, Deokgae, and He각별 can use their abilities without the Star of Investigation.
