Reze

Biodata

Background / History

Soviet Military Experiments

Reze was an orphan who suffered severe malnutrition in early childhood. At the Soviet Union’s Experimental Base, she received adequate food and accommodation, but was eventually forcibly fused with the Bomb Devil’s heart. Becoming a Weapon Human halted her physical development at seventeen 63 101 110 141 142.

After the experiment, the military tightly restricted her freedom and trained her to prioritize missions through detached, rational decision-making. She wanted an ordinary life, but feared punishment for entertaining wishes outside her assigned role. Before meeting Kotone, she had never attended school or played video games 65 72 110 143.

Assignment to Asaba Kotone

Reze approached Asaba Kotone after he arrived in Moscow through the International Exchange Program. Posing as a transferred Public Safety Devil Hunter, she became his partner in Division 1 and used flirtation to establish intimacy. Her initial affection reading remained at zero despite her apparent enthusiasm 61 63.

Her superiors arranged for her to live with him. While maintaining their partnership, she also intercepted a Western European spy photographing Kotone. She eventually drove him to the outskirts and demanded that he surrender Pochita, revealing the purpose behind her approach 64 67.

Kotone refused and trapped her in the Kamui Dimension before she could complete her transformation. Rather than forcibly changing her loyalties, he offered to help her gain an ordinary person’s freedom. After he released her, Reze returned to human form and agreed to trust him 67 68.

Gaining Her Freedom

With Reze’s consent, Kotone tested his Genjutsu on her before using it to control key Soviet military officials. Once those officials were under his influence, she stopped receiving missions and effectively gained her freedom. She decided that she wanted to accompany him when he returned to Japan 69 70.

Her military conditioning nevertheless remained difficult to overcome. During a Brown Bear Devil ambush, she hesitated to expose her Weapon Human identity, allowing Bokelin to suffer severe leg injuries while saving Nick. Reze then transformed and destroyed the devil’s head. Kotone concealed her transformation through Kamui, but she remained troubled by her delay and blamed herself for failing to prevent the injury 72 73.

Life in Japan

Reze traveled to Tokyo with Kotone, explaining that her Moscow Public Safety identity was fabricated and required no formal transfer permission. She chose to continue devil hunting alongside him and passed Tokyo Public Safety’s admission test without transforming, repeatedly wounding the test devil with a dagger while remaining untouched 74 75 77.

She became close to Kobeni Higashiyama and assisted with Akane Sawatari’s training. While accompanying Akane and Chun Zhen Ding Yilang on patrol, she recognized a Muscle Devil’s hostage deception, freed the controlled child, and killed the devil before it could harm them 74 107.

After serving in Special Division 2, Reze accepted Kotone’s invitation to join Special Division for Devil Affairs 1. She later enrolled with him and Makima in Sakuradai High School’s Class 2-4 to investigate predicted devil incidents. This assignment also gave her the school experience she had never had 106 115 141 143.

The Nostradamus Prophecy

When Kotone asked his companions to take shelter before the Nostradamus Prophecy, Reze refused to hide and insisted on facing the disaster beside him. She accepted his condition that she first settle everyone else somewhere safe, and completed those arrangements before returning to him 239 240.

Reze transformed when the Death Devil appeared before Kotone, but Makima stopped her, explaining that she could not hurt their opponent. After the Death Devil adopted the name Setsuna and moved into Kotone’s home during a temporary peace, Reze openly objected to her occupying his bedroom 244 252.

Appearance

• Human form: Violet hair, green eyes, a delicate face, and a choker bearing an ornament resembling a grenade pin. At her introduction, she wears a Moscow Public Safety uniform and white sneakers 61.
• Physically seventeen: Her Weapon Human transformation permanently arrested her aging and further bodily development 141 142.
• Bomb Weapon Human form: A torpedo-shaped, devilish head; an apron woven from detonators; and bomb fuses coiled around her arms. Her initially depicted transformed outfit leaves most of her legs exposed 67 82.
• Later clothing: Wears a school uniform for her undercover assignment and an apron or smock while cooking and cleaning at home 134 141 175.

Personality

Reze is playful, perceptive, and skilled at presenting an appealing persona. Her early blushes, affectionate nickname “Koto,” and romantic advances are deliberate tools of her assignment rather than proof of genuine attachment. Kotone’s Catalogue allows him to distinguish that performance from her initially nonexistent affection 61 63 65.

Her military upbringing makes her capable of ruthless action, but her desire for ordinary experiences survives beneath that conditioning. After gaining freedom, she struggles to replace mission-first thinking with choices of her own. Her distress over Bokelin’s injury shows how seriously she takes the consequences of that struggle 65 72 73.

Once genuinely attached to Kotone, she becomes openly affectionate and protective. She worries about outliving him, offers her blood when he is weakened, and refuses to leave him to face the prophecy alone. Although she teases him about bringing home other women, she treats Kobeni as someone to protect rather than displace 74 82 101 175 239.

Abilities & Skills

Bomb Transformation

Reze pulls the pin at her neck to transform into the Bomb Weapon Human. Her powers come from the Bomb Devil’s heart forcibly implanted by the Soviet military 67 101.

• Explosive limbs: Turns her right leg into a bomb and detonates it against the Brown Bear Devil, destroying its entire head 72.
• Explosive propulsion: Uses explosions from her feet to move faster than nearby hunters can visually follow 72.
• Target detonation: Attaches a fuse to the Minotaur Devil and causes its body to explode 81.
• Concealment difficulty: Her explosive attacks are conspicuous, making transformation difficult to hide during ordinary Public Safety work 65 72.
• Upper limit: Makima explicitly warns that Reze cannot hurt the Death Devil 244.

Weapon Human Physiology

Her hybrid body preserves her human personality while granting the persistent survival traits of a Weapon Human 65 70 73.

• Agelessness: Her body remains seventeen and no longer develops 141 142.
• Revival and restoration: Weapon Humans can repeatedly revive and recover their bodies; Kotone specifically considers Reze revivable when agreeing to let her accompany him into danger 70 240.
• Contract restriction: She cannot make contracts with other devils, a limitation previously tested by the Soviet military 70.
• Genjutsu vulnerability: Kotone successfully controls her during a consensual test, although the technique costs substantially more energy than controlling an ordinary human 69.

Close-Quarters Combat

Reze remains a formidable combatant without transforming, combining speed, agility, dagger work, and unarmed techniques 77 107 115.

• Evades a strong test devil for several minutes while inflicting repeated nonfatal dagger wounds 77.
• Severs the Muscle Devil’s connection to a child, then cuts the devil into pieces before it can effectively respond 107.
• Uses chokeholds, including a rear naked choke during her confrontation with Kotone and Makima 64 115.

Espionage and Devil Knowledge

Her spy training includes convincing acting, emotional composure, surveillance awareness, and extensive knowledge of Soviet devil records 107 120 142.

• Maintains a fabricated Public Safety identity while concealing her military affiliation from ordinary colleagues 63 74.
• Recognizes the Muscle Devil and its control mechanism at a glance 107.
• Has specifically researched Quanxi as a person of military interest 134.
• Speaks Japanese and Russian, switching to Russian to tease Elena 175.

Equipment / Weapons / Items

• Neck pin and choker — The pin at her neck is her transformation trigger 61 67.
• Dagger — Used in her Public Safety assessment and to free the Muscle Devil’s hostage before killing it 77 107.
• Detonators and fuses — Features of her transformed body and outfit; fuses can also be used to turn a target into a remotely detonated bomb 67 81.

Relationships

• Asaba Kotone — Initially an assignment target approached through seduction; later her trusted partner and lover. He frees her from military control, and she publicly declares that her dream is to become his wife 63 67 70 115 142.
• Bomb — The female devil consciousness within her heart. Their forced merger initially leaves them distant, but a conversation encouraged by Kotone improves their rapport. Reze retains complete control of her body 101.
• Kobeni Higashiyama — Close friend and fellow lover of Kotone. Reze reassures her that she does not intend to replace her, promises to protect her, and eventually confides her former spy identity to her 74 137.
• Makima — Romantic rival and later teammate and classmate. Their first meeting nearly becomes a fight, but they establish a workable peace and continue living alongside Kotone 115 141.
• Pochita — Her original retrieval target. She later learns more about his significance as the Chainsaw Devil and recognizes that Kotone protects them both 67 163.
• Akane Sawatari — A novice hunter whom Reze helps supervise. She saves Akane from the Muscle Devil’s deception and tells her to study devil characteristics 107.
• Captain Volkov — Her nominal captain at Moscow Public Safety. He mistakes her staged intimacy with Kotone for romance and does not know her military identity 63.
• Elena — A fellow Soviet whom Reze teases in Russian after recognizing her feelings for Denji 175.
• Setsuna — The Death Devil, whom Reze continues to regard as an enemy despite a temporary truce. She resents Setsuna’s intrusion into Kotone’s home and bedroom 252.

Catalogue Record

Reze occupies the Catalogue’s fourth page, unlocked when Pochita’s affection reaches 50%. These readings measure her affection for Kotone, not her combat strength; the listed Constitution rewards go to Kotone 36 61 65.

Trivia

• The Catalogue classifies Reze as human, because her personality remains her original human personality despite the implanted devil heart 65.
• Pochita’s erasure of the Bomb Devil removed the name and concept of bombs from human memory, but did not eliminate Reze’s hybrid existence. She calls her heart “Bomb” in the sense of “bang,” without initially knowing its erased identity 72.
• Reze and Makima tie for second place in Sakuradai High School’s Monthly Exam, behind Kotone 153.
