Magical Girl Lyrical Nanoha EXCEEDS Gun Blaze Vengeance Episode 12

Thirty years ago, the world was nearly destroyed by the sudden appearance of unknown "invasive alien species." Humans and these “invasive species” continue to vie for living space, and while humanity’s safety is currently barely secured, the world could be destroyed at any moment. Living in fear of death and destruction, people go about their daily lives as if trying to avert their eyes from danger and disaster. In this world, the United Nations Hazardous Species Investigation Agency, "EXCEEDS," has begun operations to ward off crises and disasters caused by invasive species. The story begins on the island nation of "Mizuho" in the Far East. Shina Hisase is a young invasive species extermination hunter living on a remote island. What incident will befall Shina, who wishes only to live quietly with her younger sister Setsuna, her sole remaining family member?
