Six months have passed since the victorious Battle of Britannia and the reclamation of Gallia from Neuroi invaders. Yoshika Miyafuji, member of the famed 501st Joint Fighter Wing, has come back home to Fuso and graduated from middle school. However, her fight is far from over. She receives a letter supposedly sent by her long-deceased father, containing blueprints of a state-of-the-art Striker Unit he had been working on before his death. The Unit, designed specifically for Yoshika, might be capable of harnessing her extraordinary magical powers. Meanwhile, a new threat in Europe is rising. A Neuroi nest of an unprecedented size and might has appeared over Venezia, wiping out local Witch forces and instantly swallowing the northern part of the country. To make matters worse, a newly spotted humanoid type of Neuroi is attempting to come into contact with humans. Yoshika, incapable of abandoning her friends on the front lines, must once again venture to the war-torn continent.

After fending off the threat of a Neuroi invasion of Romagna and destroying the enemy's nest over Venezia, Yoshika Miyafuji goes back to her home town in the Empire of Fusou. Despite the loss of her magical and healing abilities, the former officer of the 501st Joint Fighter Wing wants to continue studying medicine. This is in order to help those in need, both civilians and those on the front lines alike. She receives an invitation from a prestigious school in Europe and decides to accept the offer, embarking on a journey back to the war-torn continent. However, a new danger arises, as more and more Neuroi manage to break through human defense lines, appearing unnoticed in supposedly safe areas and disturbing the balance of power in Europe. Yoshika's sense of duty collides with her inability to pilot a Striker Unit, but with her friends in peril, it seems that there is only one thing she can do.

In order to keep ocean peace, PKN was organized. It consisted of the state-of-the-art battle ships of various countries. However, they were raided during the foundation ceremony by the unidentified organization, USR, which plotted to conquer the world. They couldn’t be much for the submarine UX which was operated by Admiral Red of USR. But an old Japanese submarine, the 707 saved them, which was operated Captain Hayami at the risk of his life. One year later, succeeding to the 707, which had been ruined during the former fight, newly developed submarine, the 707 II, went for a sail. Among the crews, there were boys, such as Kenji, Goro, and Senta, who had been trainees. PKN formed a fleet led by the Great Guardian, which was the latest battle ship of the United States. However, the attacks of Submarine U were very server, and the fleet was defeated. Then, the 707 arrived. As soon as Red noticed the 707, he was glad to reunion with his rival and began to fight. Escaping from the submarine attack, they hid the 707 in the valley. But Red tried to destroy the valley in order to put the 707 into the torrents of mud. The 707 nearly escaped from it and got in the crater. However it was the pure water layer where the submarine couldn’t float up. At the moment, numerous torpedoes launched to the 707.
