Plot

Shuji, a high school student in a Hokkaidō coastal town, discovers his girlfriend Chise's exchange diaries at an observatory, prompting him to reflect on their relationship through flashbacks. Their romance begins awkwardly when the shy Chise confesses her feelings, though neither possesses the emotional maturity to navigate the relationship effectively.

During a routine trip to Sapporo, enemy bombers attack the city. Amid the chaos, Shuji witnesses a small flying object intercepting the bombers before discovering Chise with mechanized wings and weaponry fused to her body. She reveals her involuntary transformation into an ultimate weapon by the Japan Self-Defense Forces, designed as Japan's last line of defense.

The central conflict revolves around Chise's deteriorating humanity as the weapon system overtakes her physiology. She struggles to reconcile her mechanical enhancements with her human identity, a crisis compounded by her deepening bond with Shuji. This relationship ultimately becomes key to her self-acceptance. Secondary narratives explore civilian experiences during wartime, including military spouses, enlistees motivated by loved ones, and bombing victims.

Characters

;
:
:
: Chise is a shy, academically struggling student who excels only in World History. Frequently hospitalized during childhood, she has few friends beyond Akemi. With Akemi's assistance, she begins dating the distant Shuji, relying on manga for romantic guidance. Unwillingly transformed into a weapon, she grapples with her fading humanity as her body loses warmth, heartbeat, and sensory perception—except for heightened vision. Her condition deteriorates until she becomes a merciless force, though her love for Shuji remains her last human connection. He helps her reclaim her humanity by proving only humans can love and protect others, enabling her to destroy her weaponized form. This act challenges the definition of an "ultimate weapon," revealing her soul—not her body—as the true power.

:
:
: Shuji is a 17-year-old high school student with above-average grades and a background in track. Initially hesitant about his relationship with Chise, he views it as complicated but gradually develops deeper feelings. After briefly reverting to friendship, he recognizes his love for her—a realization complicated by the return of his first love, Fuyumi. As the sole civilian aware of Chise's identity as the ultimate weapon, he guards her secret while struggling with guilt over his perceived failures. Eventually, he fully commits to protecting her, dedicating himself to standing by her side.
;
:
:
: Akemi, a childhood friend and classmate of Chise and Shuji, serves as Chise's closest confidante, often advising her on romantic matters. Though outwardly embodying a tomboy persona, she privately struggles with self-doubt regarding her appearance. She consistently defends Chise when Shuji's careless remarks cause emotional distress, demonstrating steadfast loyalty.
;

:
: Atsushi, Shuji's best friend, is a grounded and open-minded individual with a strong interest in military affairs. He ultimately enlists in the Japan Self-Defense Forces to safeguard the person he loves.
;
:
:
: The regiment leader and Fuyumi's husband is the sole survivor of Chise's original platoon. His physical and personality resemblance to Shuji initially attracts Chise, who appreciates being treated as an ordinary person rather than a weapon. His military background and relationship with subordinates, including Mizuki, his former commander, further define his character.
;
:
:
: Fuyumi, Tetsu's wife, previously coached a track team where students addressed her as "Fuyumi-" due to their minimal age difference. She frequently experiences loneliness while her husband remains stationed with military forces. The story later reveals her past romantic involvement with Shuji, who admits his feelings stemmed from physical attraction rather than genuine love.
;
:
: Mizuki served as the prototype for the weapon system later implemented in Chise. A former officer severely injured in combat, she returned to duty through the experimental augmentation program. Having worked under Tetsu as his superior, she developed unrequited feelings for him. As one of the few who understood Chise's condition firsthand, having undergone similar modifications herself, Mizuki demonstrated consistent sympathy toward her.

:
: Take stands out as the most outgoing member of Shuji's friend group and maintains a relationship with Yukari, becoming the first among his peers to have a girlfriend.
; Nori
:
: Nori, the least mature of Shuji's friends, maintains a naive outlook, insisting their hometown remains safe from war despite growing threats. He harbors strong romantic aspirations and envies Take's relationship status.
; Yukari
:
: Yukari, Take's girlfriend, withdraws from school following his death. While she later enters a new relationship, she outwardly maintains she will never again experience deep romantic attachment.
; Takamura
:
: A young soldier from Chise's former company deeply admires her, crediting her combat prowess with saving his life during their service together.
; Kawahara
:
: The lead scientist overseeing Chise's case is an anxious individual, constantly dabbing his forehead with a dark-blue handkerchief during tense moments.
