The opening blitz is pure adrenaline: orchestral war movie energy, witches screaming through the sky on striker units, the Neuroi obliterating everything in their path. You get the full world explained in minutes, weapons and strategy crystal clear, no throat-clearing. One episode of setup that burns hotter than most pilots twice its length.
Extraterrestrial invaders called the Neuroi descend on Earth during the 1940s, leaving civilization in ruins. Humanity's only defense comes from Striker Units: magical exoskeletons that grant flight and combat capabilities to young women with supernatural gifts. These witches form an international military force to push back the alien threat. Among them is a girl with dormant magical potential far beyond her peers. Raised in relative peace while others trained for war, she's spent her life hoping to channel her power toward healing. That quiet existence shatters when she's recruited into active duty. Her untrained abilities make her both a liability and an asset as she joins the ranks of experienced fighters. The OVA strips away the bigger war narrative to focus on character moments and camaraderie among the witches. It balances action sequences with lighter, character-driven scenes that reveal who these soldiers are when they're not fighting aliens. Think found-family bonding mixed with high-octane combat and the strange aesthetics of magical militarism.
