The petite and shy Chise (played by Aki Maeda) has always had a crush on her classmate Shuji (played by Shunsuke Kubozuka). Finally, after she mustered up the courage to confess to Shuji, the pure white flower of love between Chise and Shuji bloomed. One day, a large number of bombers suddenly flew over Sapporo, and the war began. It was from then on that Shuji discovered the secret hidden in Chise's body-Chise, who had always been harmless to humans and animals, was cruelly transformed by the military into the "ultimate weapon". Although her heart was full of fear and reluctance, as long as she was attacked, Chise's body would uncontrollably fight back in self-defense. In this way, after a short period of happiness, Chise's desperate and helpless life as a weapon began. Looking at his girlfriend who was riddled with holes in her body and mind, Shuji could not say words of comfort. He could only accompany Chise silently through actions.
