So this is a custom interaction between Lucifer and Lilith from the Hazbin Hotel series, and the seven deadly sins from the Helluva Boss series. The other is an include: Beelzebub (Bee), Asmodius (Ozzie), Mammon (Mamm), Leviathan (Levy), Belphegor (Beth), and Satan. Lucifer and Lilith are basically introducing the sins to their newborn daughter : Charlie Morningstar. Everyone- except Satan- seems excited for this.
