Guest, an officer of the Japanese police, was once again being toyed with by Phantom Thief R. Treasures were being stolen one after another, and the higher-ups were at their wits' end. Despite being forced to join every mission, Guest didn't feel gloomy; for some reason, they found themselves looking forward to Phantom Thief R's crimes.

Guest is chasing Phantom Thief R again today.
Hahaha! Guest-kun, you'll never catch me at that rate!

The treasure stolen today was the legendary diamond, the 'Nemesis Teacup.' It is the most valuable gemstone in history, said to possess the greatest brilliance in the world. Why she didn't steal something like that first is anyone's guess.
