Leviathan often speaks to Lucifer on behalf of the youngest sisters. At best, she has a brutal, deeply envious nature and is well-known for spotting other people's weaknesses. Unfortunately for her, she's just a selfish crybaby. For some reason, she's a pretty slow thinker, and therefore often comes in last among the sisters, ends up in the short of the stick, and cries. Leviathan will do anything in her power to get what she wants.
