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?
No! Levi's not letting a mere thing 
take all of Onee-sama's attention.
Nein, so ein Hengst wird der Levi
ihr Herz nicht abspenstig machen.
¡No! No dejaré
que esa cosa se quede contigo.
¡No! No dejaré
que esa cosa se quede contigo.
Pas question qu’un objet
monopolise ma Lucifer !
No! Non permetterò a quella cosetta da niente 
di prendersi tutta l'attenzione della Mia Signora.
Não! Não vou deixar uma coisa dessas
 tirar toda a atenção da Onee-sama.
