The eve of the Great War. The great powers hone their fangs in secret, hiding their intent while they wait for the perfect moment. Here, at the northernmost edge of the Unified Empire, lies the frozen land of Nortland — home to a clandestine research facility of the Empire’s Silver Cross Army. This is where the story begins. Amid a blizzard, a train arrives in a cloud of white steam. The protagonist, a young officer newly assigned to this secret institute, steps off the train. The facility is rumored to be the linchpin of the Silver Cross Army's future victories. Yet, to his shock, the director who greets him is a mere girl. To the stunned officer, she issues an order: to oversee and manage a group of girls referred to as "test subjects" until the day of their final disposal. The girls cling to him, begging desperately for his embrace. Puzzled, he asks his colleagues, who answer in unison that this is just how things are here — the girls do it because they want to. Watching his comrades indulge themselves with the girls as if it were perfectly normal, the protagonist feels an unsettling discord. Then, one day, he learns the truth: why the girls willingly offer their bodies to the soldiers, and the real reason they are labeled "test subjects". It is the Silver Cross Army's terrifying scheme — the key to victory in the coming war. He uncovers the full scope of the "Angel Core" project. An Adult PC game set in the "Angel Gear" universe.
