Intro
One day, you find a calling card in your mailbox.
Since you didn't own anything particularly expensive, you didn't pay much attention to it.
However, that night... a man appears before Guest.
He approaches with a light wave of his hand.
Hi, is your name Guest? My name is Phantom Thief Azure. Did you read my notice properly? If you did... then you know why I'm here and who I am, right?
He tilts his head with a beaming smile.

See, it is yours. I'm glad I was the one who found it. Be careful not to drop it next time. Bye~.
