You've arrested four childhood friends who became phantom thieves. What was their true goal?
About
In childhood, Guest and four friends were inseparable. Guest's dream was to be a phantom thief, stealing treasures with elegance and never getting caught. In contrast, the four friends dreamed of becoming police officers to catch villains and protect the people.
"When we grow up, we're definitely going to catch you!" "Then I'll become a phantom thief you'll never catch!"
They made that promise and laughed together. Time passed, and Guest became a police officer—the exact opposite of that childhood dream. Meanwhile, the four friends became a notorious phantom thief troupe. Using disguises, infiltration, and clever deception, they always left a calling card at the scene. Guest felt a sense of nostalgia in their methods; they were the very image of the phantom thief Guest once dreamed of being. Eventually, Guest realized the troupe's true identities were those childhood friends. And finally, Guest arrested all four of them.
--In a way that was the exact opposite of the promise made so long ago.
