As the final battle with the Neuroi goes on in Romagna, Yoshika and Sakamoto face major challenges. Will they succeed?

The Allied forces make their way for the Neuroi nest over Romagna and yet the girls are asked to play a lesser role than they'd like. Meanwhile Sakamoto battles with her ever-decreasing magical abilities and her struggle to master the True Reppuzan.

Mission command issues an order for the Witches to attack an island that has become a Neuroi stronghold, in the hopes of preparing them for the impending final battle.

Perrine stops by a small village in Gallia to help them in their restoration. Right after completing building an elementary school, she hears a young girl speak sadly that her friend cannot come to the school because of the local bridge being destroyed. Perrine carefully contemplates how she can repair this bridge.

Miyafuji sees Sakamoto practicing the Reppuzan and asks her to teach her the attack that has been handed down in Fuso since time immemorial. Sakamoto refuses. Miyafuji wants Sakamoto to respect her more, so she'll teach it to her. Unfortunately, she is having trouble flying. That's when the naval fleet from Fuso runs into trouble and Miyafuji has her chance to prove herself.

The maintenance group finally finishes building the bath at the base. After working up a sweat with drills, the girls go to relax in there. But then the Neuroi alarm is sounded and a big commotion occurs!

As Sakamoto and the girls attack an incoming Neuroi, they notice that the smaller Neuroi are not vanishing. From this they discern that the main Neuroi controlling them is in another location. They find out that the core cannot be reached with normal propulsion or magic power alone. The Witches launch a plan to get to the core and attack.

After the Witches have become accustomed to life in the new base, they find that their food supplies have run out. They go to the city of Rome to buy more. Lucchini, a native, leads the way, as Shirley drives the truck and Miyafuji buys the food. The party heads for Rome, but when they arrive Lucchini vanishes!

As the Witches ready themselves for the battle against the Neuroi in their new base, a package from Karlsland arrives: a secret weapon using their latest technology! Shirley issues a challenge to the proud Barkhorn.

With a 6 month gap since the battle of Brittania, Lynne, Perinne, and Miyafuji all struggle with their training. Sakamoto sends the three of them to an island to undergo basic training again. What awaits them there?
