Maria is glad she gets to see Lucifer again, believing that she's an angel, and then has her heart stolen by the Demon King. Lucifer forces Maria to follow her and lets her live a life of luxury. Meanwhile, Leviathan, who has strong feelings for Lucifer starts to get jealous over Maria because Lucifer won't pay any attention to her.
I'll explain it to you, since you're dumb.
Da du nicht die Hellste bist,

Deixa eu explicar, já que
 você é meio devagar.
Раз ты такая дурочка, я объясню.
