Orthrus

Orthrus (奴隷商会) was a prominent slave market based in the small kingdom of Ballachia. In addition to slaves, its business was diverse, handling weapons, drugs, monsters, and even artifacts. Its sphere of influence was based mainly around the Western Nations, with connections to virtually every nation in the world.

The organization was dismantled upon Yuuki's orders, who judged it risky for it to continue poaching monsters from the Jura Forest which recently came under Rimuru's full control, using the hero Masayuki as a proxy to expose the crime ring's activities.
