Captain Varrot instructs all Squad leaders to take a break following the Fouzen operation to recuperate and restore morale. When Rosie is asked by Squad 7 to represent them in a talent contest, she refuses to do so and storms out in anger. When she meets Isara, Rosie tells her that armed Darcsen guerrillas came to take shelter in her home during the First Europan War to hide from Imperial soldiers when she was a child. Rosie's parents were killed by the guerrillas in the crossfire when they wrongly accused her father of betraying their location to Imperials. Despite what had happened, Rosie is traumatized by her past and still doesn't want to sing. Welkin decides to try persuading her himself after hearing what Isara had told him that she would avoid being present in the talent show to get Rosie to participate. Faldio later returns back to the barracks with Isara in tow; Rosie had performed even with Isara present as an order from Faldio. Her performance cheers the militia personnel. After the concert, Faldio tells Alicia that he loves her.
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.
