Aboard Monstra, Cinder Fall recovers from injuries sustained from her fight at Amity, and reports to Salem alongside her master's subordinates. Salem tortures Cinder for her failures, and orders her to free Watts from his imprisonment to claim the Winter Maiden's powers, in a race with her experiment, The Hound. Salem orders Tyrian Callows and Mercury Black to Vacuo, and launches her attack as they leave.
In the farmlands of Atlas, Salem begins to conjure various Grimm through Monstra. Ready to fight, a legion of Atlas Soldiers and advanced Atlesian Paladin-290s meet them. The two enter into a fight which appears to last the entire day.
After arresting Yang's group, the Ace-Ops receive orders to go on a mission inside Monstra to blow the creature up from the inside with bombs. Jaune and Ren convince Winter to let them scout the monster and make sure the coast is clear in the operatives' stead, while searching for their friend Oscar Pine, who was held hostage in the whale, in the process.
In "Witch", the war continues with many Atlesian soldiers, including the Ace-Ops and Team FNKI fighting the seemingly never-ending army of Grimm. Winter prepares a platoon of soldiers including Marrow to clear a path to Monstra to deliver the bomb in an attempt to stop the whale.
