The 48 Fiends

A legion of demons who made a deal with Kagemitsu Daigo to rule the world, in exchange for 48 of his son Hyakkimaru's body parts. They do this because it was foretold that Hyakkimaru would be the one to kill them, and so they sought to disable him from doing so. However, the prophecy becomes self-fulfilling because they gave him a reason to hunt them down and kill them.
