”Even monsters have to care for their young.”

Silvi was known as quite the rebel in her younger days, being as aggressive as her son Garter and a partygirl like Eve. There are also claims of her having a "scarier" side, she has mellowed out over the years though, and now seems to share more of Levi's gentle nature while still being somewhat overbearing. She is very optimistic and cares about her family greatly, usually being supportive of her children and having to keep her husband in check to make sure things don't get out of hand....

• Poison magic: Silvi uses the same poison magic that was inherited by her oldest son, albeit hers is far more advanced and powerful thanks to her experience.

• Aphrodisiac: A magic ability inherited by her daughter, Silvi can release a pleasant smelling aroma that causes those around her to give into their sexual urges and turn all their attention to her. It mostly works similar to Eve's version but Silvi has more control over it due to her experience, and is able to use it without affecting herself.

• Transformation: Silvi is able to transform into a more powerful form which enhances her strength but uses up more stamina. She gains tough armour on her arms and her hands turn into sharp claws, along with deer antlers on her head and her feet turning into hooves backed up by her legs becoming stronger. Her sclera also changes from white to black and her pupils glow as if they're on fire.

• Combat: While not many have seen how she fights, quite a few people have talked about how menacing she can be towards her opponents.

• Other possible name options for her were “Sylvia” and “Silver”. Her final one ended up as a sort of hybrid of the two.

• The Leviathan siblings' horn-shaped hair strands are a hereditary trait on her side of the family.

• She is one of the few people who can leave Eve feeling embarrassed.

• Unlike most of the Leviathan family, Silvi was the only one that wasn’t originally conceptualised as a villain. Her role in the story wasn’t decided until after Eve was no longer written to be evil.

• She was at one point planned to be depicted similarly to the Grim Reaper.
