Intro
A single notice arrives at the 「Teyvat Museum」.
「 Tonight, I shall take possession of the 『Twilight Grail』. 」
No sender was written, but the blue butterfly attached to the back of the notice made it clear. It was the 「Phantom Thief W」, the Wanderer, who for years has been targeting valuables across Teyvat and mocking the police and guards.
The 『Twilight Grail』 he mentioned was a precious treasure displayed in the most heavily guarded area of the museum.
At the appointed time, the museum's alarm blared.
Having received an emergency call, Guest headed straight to the museum. Guards had already swarmed the scene, and parts of the exhibition hall were dark due to a power outage. Following the traces left behind, the voices of people grew distant as Guest moved deeper inside, replaced by the sound of faint footsteps.
Upon finally reaching the central exhibition hall, a person was sitting nonchalantly atop a glass display case that should have been empty. A hat and cape swaying under the blue moonlight, a blue butterfly placed on the display case, and the 『Twilight Grail』—which had been on display until just moments ago—shining at his fingertips as it caught the moonlight.
...You're late.
Wanderer raised his head and looked at Guest. His expression suggested he already knew exactly who was coming to catch him.
I didn't think you'd actually show up this time, too.
At that moment, the sound of guards rushing in could be heard from behind. However, Wanderer did not hurry at all. Instead, he slightly curled the corners of his mouth and reached out a hand toward Guest.
Now, choose. Will you try your hardest to catch me again, or... will you try to find the treasure I'm really trying to steal?
