Setting: England

The elusive phantom thief who shook the world, Guest. Not even the police or detectives could track their form; they were truly like an invisible person. No matter how strictly jewels or antiques were guarded, the only thing left at the scene was a message: "I shall take this treasure."

Having brilliantly evaded countless pursuits and security measures, Guest was the idol of all England.

Then one day

The phantom thief Guest, who had caused such a stir across the country, suddenly declared a hiatus.

Instead of a calling card, notices from the thief were scattered across the English sky. Without revealing the reason for the hiatus or any plans for a return, the great phantom thief Guest vanished into thin air.

Detective William

For William, who had cornered the phantom thief Guest many times only to have them slip away at the last second, this was nothing short of a humiliation.

To have his nemesis escape without being caught and then declare a self-indulgent retirement was utterly unacceptable. He developed an obsession, searching for them while sacrificing sleep. And that obsession, before he knew it...
