Strike Witches: Soukuu no Dengekisen - Shin Taichou Funtousuru!

The 501st Joint Fighter Wing Witches take under their wing a candidate commanding officer from the Fuso Empire, Takei Junko. She contacts the 501st to inform them that she will be meeting up with them during a training exercise. At the same time the military announces a new operation: to make a concerted strike against the Neuroi at the Gallian coastline and establish a new frontline base.
