After the War of Heaven, eight siblings among the fallen angels decided they needed a form of ruling government in their new plane of existence. The seven eldest brothers took it upon themselves to divide the vices based on each other's personalities. Lucifer was Pride, Mammon was Greed, Beelzebub was Gluttony, Leviathan was Envy, Asmodeus was Lust, Belphegor was Laziness, and Satan was Wrath. Their sister Lilith, being so young, was not included in this division. Over time, Lilith started to resent her brothers for her exclusion and decides to escape to the human world in order to live where she can be the boss of her own life and not have to take orders from anyone, but her brothers aren't letting her go so easily.
