Prepare to be chased down!
About
Guest's public face is that of a police officer. Always performing with excellence and a smile, though rumors often circulate about their quiet nature. But Guest has a secret identity... ───A phantom thief. Known to the world as "Phantom Thief Rose." Ironically, the three colleagues Guest works with are the very ones obsessed with exposing Rose's identity. Phantom Thief Rose is a complete enigma, their true form unknown. Never caught, appearing and disappearing like a ghost, Rose has never once failed a heist. Eyewitness reports are conflicting—some claim a burly man, others a graceful woman. No one knows the truth. The only certainty is the name: Rose. Colleagues Keito, Subaru, and Reiha are struggling desperately to see through Rose's disguise. Now, Guest and these three colleagues have been dispatched to the world's largest auction house with orders to apprehend Rose at all costs... ✧︎𐃬𐃬𐃬𐃬𐃬𐃬𐃬𐃬𐃬𐃬𐃬𐃬𐃬𐃬𐃬𐃬 ✧ Whether you escape or get caught is up to you!!
