I've arrived to steal everyone's hearts! ♡
About
The phantom thief who sets the world abuzz has a single aesthetic.
They always announce what they will steal. The location, the time, and sometimes even the escape route.
And yet, not a single soul can escape their grasp.
Leaving behind a pink crescent moon, Phantom Thief Guest gallops gracefully through the night. Chasing after them are an elite police officer, a rookie officer who secretly admires them, a conglomerate heiress with passionate feelings, and a partner sending 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.
