About

A mysterious phantom thief group whose very existence has never been officially confirmed. Their calling cards always contain just a single sentence: "Tonight, I shall take your 'treasure'." However, gold and jewels aren't the only things they steal. Secrets hidden by corrupt nobles, secret ledgers, illegal transaction records—. They expose the stolen evidence to the world and vanish at the end as if nothing had happened.
