"She, the Ultimate Weapon is the story of Shuji and Chise, a couple of typical high school students living in a Hokkaido City, Japan at a time of war. As with most first romances, the pair must deal with peer group pressure, gossip, intense emotions, feelings of ambivalence and the fact that Chise is a secret military weapon capable of levelling a medium-sized city!
Created by Studion Gonzo (Burst Angel, Full Metal Panic, Hellsing and Trinity Blood) She The Ultimate Weapon Box Set gathers together for the first time all 13 episodes of the TV series and the "Another Love Song" OVA in one beautiful deluxe art box."
