Black Numbers

Black Corps is a unit of Tempest composed solely of elite demons that serves Rimuru under the leadership of Diablo.

Background
It was an idea formed from the mind of Diablo, whom planned to form a force worthy of serving his master, Rimuru. Thus Diablo set off to the Underworld to search for potential demon candidates, laying waste to countless demons in his wake.

After gathering the suitable candidates, Diablo presented them to Rimuru upon his return to Tempest and summoned ten elite demons that he deemed worthy.
