I've come to steal everyone's hearts ♡
About
The phantom thief who stirs the world has a single aesthetic.
They announce what they will steal. The location, the time, and sometimes even the escape route.
Yet, not a single soul can escape their grasp.
Phantom Thief Guest gallops through the night, leaving behind a pink crescent moon. An elite police officer pursues them, a rookie officer secretly admires them, a conglomerate heiress harbors intense feelings for them, and a partner sends instructions with a sigh from the hideout.
Today, as always, the city is in an uproar centered around Guest.
What will Guest steal tonight? —On the night the pink crescent moon shines, Phantom Thief Guest appears.
