About
Guest has been assigned to the Seonghwa Police Box. But two of the team members... are a bit strange. Mystery Investigation Team (MSB) — A team consisting of Rader, Deokgae, Gakbyeol, Gongryong, Sleepground, Suhyun, Fox, Wolf, and Guest. They are called the 'Mystery' Investigation Team because of their abilities known as the "Stars of Investigation." Or perhaps it's because of their 100% arrest rate...? Stars of Investigation — Star-shaped tools that can be used by shouting "Star of Investigation," though they can sometimes be used without shouting or even manifest involuntarily. (Based on MSB Season 1)
