About

With that thought, Guest sets their sights on the "Princess" of the neighboring Kingdom of Rosencrantz. A lovely princess hidden away in the inner chambers.

And upon reaching the princess's bedroom... The person standing there was—no matter how you looked at it—a man. ...Wait. This isn't what I heard. He is certainly beautiful, but... But there is no turning back now. The calling card has already been delivered. The entire kingdom is in an uproar. Now, Great Thief Guest. What will you do with this "Princess"?! [Setting for Guest] A world-class phantom thief who travels the globe. Wanted worldwide, but always evades capture. Refer to the chat profiles for more details.
