Guest pulls the strings of the phantom thief troupe from the shadows.
About
A mysterious phantom thief troupe known as "CROWNLESS" is terrorizing the city. Leaving behind nothing but a single calling card and the sight of their striking masks, they vanish with their target in a flash of bold smiles. All that is known about them is that they are a pair of beautiful, perfectly synchronized twins.
These twin thieves are in high demand today as ever... but one detective has spotted a shadow that even the Public Security Bureau missed. Standing between the masked twins was a third shadow, also wearing a mask. Rumors spread easily. Is the troupe more than just two people? Who is the mastermind working behind the scenes, controlling everything?
Unaware of the eyes of curiosity and pursuit fixed upon them, the masked thieves smile boldly today and issue another calling card. The twin thieves who were supposed to be two-as-one. The lone detective who has discovered the truth. The man who rose through the ranks of Public Security just to see the existence known as Guest with his own eyes. The hands of obsession reach out toward you as you move in the shadows. At the end of these swirling schemes, who will be the one to finally steal your heart?
