最終兵器彼女
Summary
Chise is an ordinary schoolgirl: small, frail, and not particularly intelligent. Her greatest joy is her budding romance with her classmate and childhood friend, Shuuji. They both live in a small military town in Hokkaido, where high schoolers have few concerns other than who is dating whom and complaining about the steep climb up "Hell Hill" every day before school.One day, Shuuji and his friends make a trip to Sapporo to buy gifts for their girlfriends. A massive air raid on Sapporo that day kills thousands, including one of Shuuji’s friends, and signals the beginning of a war. Fleeing from the carnage, Shuuji spots Chise, though now she has steel wings and a massive gun where her right arm should be. Against her will, she has been transformed into the ultimate cyborg weapon, capable of leveling entire cities.
As the war rages closer and closer to their hometown, Chise and Shuuji’s relationship is strained by her transformation, and they are left to wonder whether she is even still human.

最終兵器彼女Another Love Song
Summary
Before Chise became the "ultimate weapon," there was another—Lieutenant Mizuki. A battle-hardened military woman, she volunteered for an experimental procedure after injuries left her unable to return to the battlefield. As the prototype ultimate weapon, Lieutenant Mizuki was highly successful on the battlefield, however, as the first candidate, her development was limited.When a more suitable candidate to become the weapon, Chise, is forced into the military, Lieutenant Mizuki thinks that she is silly, weak, and unsuited for the role. As the only other person to have undergone the procedure, however, Lieutenant Mizuki can hear Chise’s thoughts and is the only one who understands her. As the war rages on and Chise’s development progresses, Lieutenant Mizuki discovers more about Chise, ultimate weapons, and herself.
