The Town of Fog Where Greed Brews
The gang travels to London to face another Mortal Sin, the Demon Lord of Greed. Maria finds a strange shop that sells a potion that purports to grant anyone their wildest desires. Lucifer makes haste to the shop's location, only for them to quickly fall into a trap, but will Maria and Levi be able to handle themselves once they're separated from Lucifer?
The Languid Diva

Beelzebub is challenged to an eating contest by Lucifer, but when they both eat as much as they can, Lucifer becomes ill and ends up in the hospital. Her magic should prevent her from getting sick, but she's severely weakened. Will her time in the hospital bring her some humility?
Unleashed Wrath
Satan, the Demon Lord of Wrath, plans on stopping Lucifer once and for all. She sets off for Earth to retrieve Beelzebub and defeat Lucifer.
