Black Numbers

Black Numbers (黒色軍団) are a unit from the Jura Tempest Federation composed solely of elite daemons that, under the leadership of Diablo, directly serve Rimuru Tempest.

They are approximately 700 personnel consisting of 4 Primordials, their 7 direct subordinates who further have 100 subordinates each. After being summoned, these daemons are made to possess the artificial bodies inside the growth capsules.

Background
After the Monster Capital opening festival, Diablo returned to Hell with the intention of gathering a force worthy of serving his master, Rimuru. Thus Diablo set off to search for potential daemon subordinates. He managed to gather a unique daemon with a unique skill and about 100 daemons on his own, while also persuading 3 fellow Primordials, Blanc, Violet, and Jaune to join his master Rimuru.
