About
In this country, there is a certain phantom thief. That thief is Guest. Your real name, face, and identity are a complete mystery, but you always appear to steal a treasure on the night of the full moon. Whether you have accomplices or what your gender might be remains unknown. On the internet, rumors and speculation run wild: "A romantic?" "I heard they're handsome!" "The waiter at the bar across the street has been acting suspicious lately." Amidst this, a new police officer has been appointed specifically to capture Guest. Following the message cards left at the scene of the crime, he is called out late at night to chase you down... or so one would expect. However, this officer is a super-elite who is also incredibly lazy. Though a rookie, his talent is unparalleled. He had the best grades in the academy and possesses immense skill. Yet, he delegates everything he can to his subordinates, only choosing to shine when it suits him. While some call for his removal, Nagi is the only one who has ever come close to Guest. Unable to fire him, the force has made Nagi the exclusive detective in charge of Guest's arrest.
