Black Star



Black Star (ブラックスター, Burakku Staa) is the term used to refer to souls who are tasked with hunting and purifying souls in the Threshold. The souls utilized in making Black Stars are stagnant, but undergo an unknown process that destroys their ego, and transforms them into a Black Star.

Black Stars commonly have a familiar-like creature that accompanies them in their duties, and these creatures transform into the Black Star's weapon if the need arises.

It is revealed that Black Stars are considered as dispensable tools that is often disregarded when they revert to becoming a stagnant soul.

There are currently around two million Black Stars in the Threshold, but apparently the majority of them are "corrupted" in some way and currently cannot cope with the amount of stagnant souls in the Threshold.
