So this is the sequel of kaitou joker and 2 kids are phantom thiefs.
1 of the kid is son of queen and joker and the other one is a random kid from school. In my opinion the only thing good is the art style. There is no story arcs so far although it is leading up to it. As the character is ok don't really know how to explain it. But for the enjoyment its really hard to understand what they're talking about and the writer is bad at explaining what the item does. Overall I feel its boring I suggest reading kaitou joker than reading this manga.
