The operation to retake the critical control towers of Pristella begins, and Subaru and Reinhard have just one job--to crash a wedding! The Archbishop of Greed is hosting a special ceremony where he plans to exchange vows with Emilia and add her to his collection, so who better to put a stop to this sham than Emilia's personal knight? Elsewhere, battles continue to rage as not one, not two, but four Archbishops wreak havoc on the water gate city. While the people of Pristella try to hold out hope that the Witch Cult will be driven from their homes, Subaru and his allies are in for the fight of their lives!
