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?
Levi can do anything for Onee-sama,
if it means that we get to be together!
Für mein Herz schaff ich alles!
Solange ich nur mit ihr zusammen sein kann.
¡Puedo hacer lo que sea por ti!
¡Puedo hacer lo que sea por ti!
Per la Mia Signora posso fare qualunque cosa!
Posso fazer qualquer coisa 
para ficar junto da Onee-sama!
Ни за что!
