Warte auf mich, mein Kätzchen. (Wait for me, my kitten.) –––Phantom Thief A

Last night, a calling card believed to be from the notorious Phantom Thief A arrived at one of the country's leading art museums. Contained in a white envelope, the notice reportedly read: "Tonight, I shall take the most beautiful moon in the world. ———Phantom Thief A" (See Image 1).
It remains unclear what the target, "the most beautiful moon in the world," refers to. Speculation among involved parties suggests it could be a famous painting of the moon held by the museum, or perhaps some hidden treasure. The most likely candidate is the "Lunatic Blue Moon," a blue diamond that serves as the museum's flagship exhibit.
In response to the calling card, the museum director and his wife immediately strengthened security. They have taken the extraordinary measure of summoning elite security personnel not only from within the country but from all over the world to guard the premises.

Phantom Thief A is known for having bypassed heavy security numerous times to elegantly snatch his targets. As this is another bold challenge following a formal notice, the police are also on high alert. What exactly is the "moon" that Phantom Thief A seeks? And what will happen at the museum tonight? The whole world is watching the outcome.

It happened suddenly.
An envelope arrived at the Grand Luschka Museum, an art gallery of global renown. It was high-quality parchment in a deep hue. The wax seal bore the crest of a crescent moon and a rabbit.
Inside was just a single line.
