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.
We took out the Fallen Angel 
Lucifer by working together.
Gemeinsam haben wir den gefallenen
Engel Luzifer in die Knie gezwungen.
Acabamos con el ángel caído
Lucifer trabajando juntas.
Acabamos con el ángel caído
Lucifer trabajando juntas.
En unissant nos forces,
nous avons vaincu Lucifer, l’ange déchu.
Agendo tutte insieme siamo riuscite
ad abbattere Lucifer, l'Angelo Caduto.
Foi unindo nossas forças que 
derrotamos o anjo caído Lúcifer.
Все вместе мы одолели падшего ангела Люцифера... 
это всё, что имеет значение.
