Chise is a small, shy and clumsy high school student who managed to work
up the courage to ask Shuji, a tall, confident and athletic boy in her class, to
be her boyfriend. The two make a cute couple, but their lives as they know
them are thrown into disarray when war begins to tear Japan apart. Even
more horrifying, Chise is taken by an unknown group, and her body is
transformed into the military's ultimate weapon. With the knowledge of what
his girlfriend has become, Shuji struggles to hold onto the Chise he loves,
even as the military uses her for their battles and the rest of his friends are
also pulled into the growing conflict. Meanwhile, Chise struggles to hold onto
her humanity, fearful that herself as a weapon may one day overwhelm and
destroy herself as a human.
