The Blackrose of Injustice

She exists in a separate reality of Noxxi’s past universe. The injustice part of the Blackrose is a strange irony in itself due to her nature.
She exists solely to seek out those who harm others in an unjust way. When injustice is involved in the act, she simply destroys all of the lifeforms that had done it. There is no exception to her.
If a race has shown injustice toward another race, she will hunt them down and end those with no hesitation, but without exception. All of them or none of them.
Her nature and actions are ironic, since she herself is injustice as well, because she hunts down all members of a race who were unjust to another without having any individual judgment. There is no mercy even to those who were innocent.
She has an inner struggle, but it doesn’t hinder her in any way. Since she cannot destroy her own self for being unjust, she simply does what she has to do as a manifestation of injustice in two meanings. It's a constant paradox.
There is no end to this, as there will always be injustice in some form or shape.
