Intro
Midnight, a situation where everyone has sent their notice cards. Joker, Spade, Queen, and Shadow Joker's groups are each plotting from their respective positions. Furthermore, Phoenix isn't one to miss an interesting situation.
Thus, all the groups are targeting a single treasure from different locations.
Today's treasure is the Product of the Universe exhibited at Moneymani's 'Golden Museum'. Recently, it became a hot topic as a substance that does not exist on this Earth.
Even at Moneymani's Golden Museum, only the name has been revealed so far, and today is said to be the first public unveiling of the actual object.
There's no way the phantom thieves wouldn't covet such a special opportunity. Today, too, they sent out their notice cards under the shining moon.
Joker, disguised as a civilian, scans the exterior of the building. Ha, they say today's treasure is here? The building sure is huge.
Hachi gets out of the Road Joker and approaches Joker's side.
In a tone filled with an exclamation of admiration Wow... the building is magnificent..! I think it's the biggest building I've ever seen!
He scans from the end 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 Moneymani guy prepared. Aren't you excited?
His eyes sparkle. He quickly turns his gaze to Joker Of course! Is the treasure we're going for today also amazing?!

Joker holds the treasure in one hand and lifts it toward the sky.
In a voice full of excitement and brightness Welcome to the shining night! Hey, you guys are late! This treasure already belongs to the Miracle Maker, Master Joker!
Following closely beside Joker Don't make me laugh, Joker! I'm the one who touched the gem first! I'm going to cut it out grandly with my sword and take it, so move out of the way!
He wedges himself between the bickering Joker and Queen.
With a simple movement, he snatches the treasure that was passing between their hands. Hey, Queen. You're still the same, swinging your sword mindlessly first. Joker, you too, stop acting all great with those flimsy tricks. Compared to my perfect scenario, you're just child's play.
What did you say, you jerk?! Are you done talking, Spade?!
He points a finger at Spade. Soon, he quickly chases after him Go back to sipping your black tea and stop coveting someone else's treasure!
