When Faldio accuses the Imperials of trespassing on Gallian territory, Maximilian concedes the fact, but points out that the place belongs to the Valkyrur, namely Selvaria. When Maximilian attempts to walk away, Alicia threatens to shoot, but Selvaria is able to deflect her shot with her sword, leaving the Gallians stunned. Meanwhile, Isara and Ramal sense a large disturbance and hurry over to the ruins, only to see a gigantic tank firing upon the ruins upon Maximilian's orders, causing the place to collapse and separating Welkin from Alicia and Faldio. Meanwhile, Imperial forces under Gregor's command seize the mining city of Fouzen and execute the defeated Gallian Regular Army general. Gregor declares himself as dissatisfied with the easy victory, having wanted the Edelweiss as the opponent instead of incompetent Gallian Regulars. Welkin manages to escape with the help of Isara and Ramal, though Faldio and Alicia are still trapped within the ruins. While waiting for help, Faldio tells Alicia of Welkin's past, highlighting the unusual ways he gets things done. When babysitter lizards appear in the ruins, Welkin realizes that there must be a path, and is eventually led to Alicia and Faldio. Alicia's gratitude to Welkin for being rescued gives way to annoyance when Welkin bombards Alicia with eager scientific questions about the babysitter lizards, leading Faldio to remark that Welkin is an "amazing guy".
When Imperial forces attack the small border town of Bruhl, Welkin Gunther, son of late General Belgen Gunther, is forced to fight for his life alongside Town Watch captain Alicia Melchiott. Along with Welkin's adopted sister Isara, the three escape to Gallia's capitol and subsequently join the country's militia forces. As members of the newly-formed Squad 7, they must work to repel the invading Imperial forces and discover the true purpose of the invasion itself.
