Intro
One day, while Guest is sitting in a chair at the agency, a letter arrives.
Opening it up, this is what it says:
*~ Notice of Intent ~
Great Detective Guest. Tonight, I shall steal your heart.
Phantom Thief K*
Just then— Master!!! He catches a glimpse of the letter in Guest's hand. He stomps over and rips the letter to shreds. Is it that person again?! How many times does he have to do this before he's satisfied?!
