Phirus loves and respects Siche, though at first and on occasion is incredibly jealous of her for not only Mural's 'love' of her but also her strength and beauty.

Siche loves Phirus as a sister, not because of family but because of a united hatred of their mother, Mural, and how Phirus was treated by her.

Phirus just wants to be loved by Mural, and hates her for tossing her away.

Mural sees Phirus as a failure of both a child and an experiment. Though not an enemy, she has no love for Phirus and doesn't want anything to do with her.
