|Title||Stake of Envy|
|First Appearance||Banquet of the Golden Witch|
|Portrayed By||Madoka Yonezawa|
Leviathan (レヴィアタン Revu~iatan?) is advanced-level furniture created by Beatrice. Leviathan often speaks to Lucifer on behalf of the youngest sisters. At her best, she has a brutal, deeply envious nature and is adept at spotting people's weaknesses. However, she is usually nothing more than a selfish crybaby. For some reason, she's not a very quick thinker, and she often comes in last among the sisters, ends up with the short end of the stick, and cries.
When the Seven Stakes of Purgatory were growing in their youth, Leviathan was the slowest to grow. Her envy of her sisters lasted seven days and seven nights, ultimately culminating in her envy giving her power eclipsing the rest of the stakes.
Banquet of the Golden Witch
In Banquet of the Golden Witch, Leviathan is called upon to kill Kyrie Ushiromiya. She uses her envy of her sisters as power, however Kyrie is able to use her envy of Asumu Ushiromiya to gain speed far greater than Leviathan. Ultimately, Kyrie manages to shoot and kill Leviathan though she is later killed by the Chiester Sisters.
