Chise's not very strong but is always trying her best in everything.
Her favorite subject is world history and her worst subject is Physical
Education. Chise became the ultimate weapon when her body was remodeled
into a killing weapon to be used in the on going world war. Chise asked
Shuji out initially under the consistent pressure of her best friend: Akemi.
Shuji
Shuji is the male main character, he likes Chise but was initially afraid
to express his true feelings partly due to his memory of his 1st love and also
to the fact that Chise is a human weapon. Shuji always thought of
himself as useless, as his fellow classmates died one by one in the war, he
became even more hopeless. In the end, Shuji realized how much Chise
means to him and gave up everything in order to protect the one person he
values the most.
Akemi
Chise's best friend. Akemi has a crush on Shuji ever since they were
toddlers, but she was afraid to tell him her true feelings.
Atsushi
Atsushi is one of Shuji's closest friends. He secretly likes Akemi
and later confessed to her only to find out that the person Akemi truly love
is Shuji. Later Atsushi joined the army in order to fight for the ones
he love.
Fuyumi
Fuyumi is older than Shuji and is Shuji's 'first love'. She's now
married but since her husband Tetsu hasn't returned home for a long time,
she's miserably lonely and once again thought of Shuji.
Tetsu
Tetsu is the regime leader. He treated Chise like a ordinary girl and
took her to go shopping despite the strict regulations and schedules in the
military. Tetsu also love his wife, Fuyumi, very much.
Yukari
Yukari used to be a member of the group that hangs out with Chise and
Akemi. But after her boyfriend, Take died (in the first episode), she
stopped going to school.
Take
One of Shuji's close friends. He died in one of the enemy bombings.
Satomi
Akemi's younger sister, she also respects Shuji very much.
Kawahara

He later wanted to save Chise when her human body was dying and she was
getting completely taken over by her machine part.
