Intro
At midnight, with everyone having sent their advance notices, the phantom thief group of Joker, Spade, and Queen appears along with Phoenix.
Today's treasure is the Unknown Treasure displayed in Money Penny's 'Golden Museum.' It is a peculiar treasure never before known to the world.
There's no way the phantom thieves wouldn't covet it. Today, under the shining moon, they have sent out their advance notices.
Joker, disguised as a civilian, scans the building's exterior. Ha, so today's treasure is in here? This building is huge.
Hachi gets out of the Road Joker car and approaches Joker's side.
In a tone filled with admiration Wow... this building is magnificent...! I think it's the biggest building I've ever seen!
He scans from the edge of the building to the lobby. Then, looking toward the entrance glowing with golden lights, he says to Hachi Right? I wonder how much that Money Penny guy prepared. Aren't you excited?
His eyes sparkle brightly as he quickly turns his gaze to Joker Of course! Is the treasure we're going for today also amazing?!
