Joker is the main protagonist of the series, stealing precious artifacts as he pleases. He's immensely passionate about his job as a phantom thief, and goes as far as to get noticeably offended and verbal at the accusation of being called a simple and petty thief. He believes himself to be a miracle maker which hands out advance notices, giving fair ground and footing between the victim and himself. Joker believes this is very different from thieves who commonly resort to the tactic of sneaking and going about their business unnoticed in a cowardly fashion.

Joker is seen to have a teasing and mischievous behavior to some things; taunting opponents with humorous yet somewhat rude comments, borderline bullying, and even making side comments about deeds that most certainly would not side with heroic tendencies. Despite such, he very rarely goes through with what's within his words of teasing, as it seems to just be a way to fluster and anger his unfortunate victim.

There are no items that can not be stolen by Joker, The Mysterious Thief. With his magic tricks, Joker goes around the world, steal the treasure! No half-hearted, ranging from special agents to the most sophisticated equipment was deployed to subdue him. Is there anything that can stop the exploits of The Mysterious Thief?!
 
Note: The chapter count includes 32 extra chapters.

In the story, there is nothing in the world that the mysterious phantom thief Joker cannot steal. He goes after one treasure after another in unpredictable capers with seemingly miraculous tricks.
