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?
Don't forget that I'm a Demon Lord.
Denk daran, auch
ich bin ein Dämonenfürst!
No olvides que soy un demonio.
No olvides que soy un demonio.
Je suis un seigneur démon,
ne l’oublie pas !
Sono una Potenza Demoniaca, ricordatelo.
Não se esqueça que sou
 uma Rainha Demônio.
