Pre-GameEdit

In Last Specter, Crow is the head of the black market. The children who run the black market (the Black Ravens) find things in rubbish dumps and alleyways, then clean and mend them before auctioning them off on the market. Some things they find (such as Arianna's ocarina, which was found in a rubbish pile according to Louis) hold real value, but most of it is just junk. Nevertheless, the black market is very successful. There are 9 Black Ravens; Crow, Marilyn, Nabby, Scraps, Tweeds, Wren, Socket, Louis and Badger.

Professor Layton and the Last SpecterEdit

The Black Raven appears early into the game as a mysterious and antagonistic character. He leapt down from a rooftop onto a stall Professor Layton, Luke, and Emmy were browsing. Emmy proceeded to chase the Raven in a parkour fashion until he vanished completely. He stopped momentarily to tell the three that they must "complete [his] body" in order to become members of the black market, which was a hint to them to find the medals.

The Raven and the black market turned out to be the idea of a group of schoolchildren led by a boy called Crow. The Raven was a way of testing the potential member to see if they were worthy. In order to give the impression of moving incredibly quickly from place to place, the children dressed up as several Ravens, each trading places with the other at certain intervals.

Later on, the Black Ravens help Layton twice. The first time, Layton needed help with setting up traps for the Specter around Misthallery, so he called upon them. When Descole revealed himself and set his Specter machine to destroy the town, the Black Ravens helped Layton collect parts for and build a catapult, which temporarily took out the machine.
