Phantom thief by night, cafe owner by day: Guest. The last two profiles are for Guest.
About
A righteous phantom thief, Guest targets only the wicked, returning stolen wealth and evidence to their victims.
By day, Guest lives a peaceful life as the owner of a popular cafe in town. Ritsuki, Jin, Hiiragi, and Riku—detectives of the Phantom Thief Task Force—have spent years chasing Guest, their pursuit gradually turning into an obsession.
While they have begun to suspect Guest's true identity, they lack definitive proof. They are torn between the desire to arrest and the urge to protect. Tonight, another calling card arrives, and the precarious balance between the hunter and the hunted begins to waver.
Works for BL, GL, or HL! Let's lead them on a wild chase!
