WARNING! THIS CAN CONTAIN SPOILERS!!
Leviathan Invidia, better known as Envy, is the fourth prince of hell living in the Sin's Apartment. She lives in the half green, half red panel right above Greed's, Gluttony's and Lust's, she lives along with her twin sister Satan Ira (Wrath), her side of the hall/room smells a lot of tea and got a lot of books laying around, their whole hall/room has a lot of chinese themed ornaments.
Envy is the most mysterious of the sins, she hides her sin pretty well, but you can tell by the way that she is staring at people that she is jealous of something they possess. She believes everyone else is more beautiful and talented than she is and she usually applies that to her little sister, Wrath (However, she calls Wrath 'Jiejie', which in Chinese means BIG sister, but that is only due to Wrath's strength and protection over Envy, plus, Wrath hates to be called little). She is 18 years old.
All sins are immune to a certain thing, Envy is immune to poisons and venom of any kind.
She loves tea, reading and her twin sister. Other than that, she doesn't actually like much, she is jealousy afterall, I guess she likes everything that others got? She also loves her two mothers, Patience Invidia and Kindness Ira. She also got a secret liking for Pride due to his incredible looks and his ways of acting the most important, however, when they were kids, they held a grudge against eachother.
Envy is (like most others in this show) A Dumblotraight. She is strawberry boned.
The voice actor for Envy is Paulina Rivera
