Satan, the Demon Lord of Wrath, plans on stopping Lucifer once and for all. She sets off for Earth to retrieve Beelzebub and defeat Lucifer. Lucifer is significantly weaker than Satan, but plans on accepting her challenge anyway. Maria watches from afar and tries to remain faithful to Lucifer, and Levi struggles against Satan.
