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?
I only did this because 
Onee-sama said I had to.
Ich mach das nur, weil mein
Herz mir das so gesagt hat.
Solo lo hice porque Lucifer me lo pidió.
Solo lo hice porque Lucifer me lo pidió.
Je te le dis clair et net,
si Luci avait pas insisté…
L'ho fatto solo perché me l'ha chiesto la Mia Signora.
Só fiz isso porque a 
Onee-sama mandou.
Скажу сразу! Я спасла тебя только 
по настоятельной просьбе сестрицы!
