Background

Kujo Ryuko grew up admiring her older sister, Kujo Iruka—the celebrated “Empire’s First Archer,” “Star of Hope for Humanity,” and “Empire’s Tiger.” Ryuko sought to become someone equally radiant, but Iruka’s fall into the Abyss as the Abyss of Eternal Smile destroyed that foundation. Ryuko subsequently made it her ultimate goal to personally kill her Anomalous older sister. 18

She was formerly a student of Shiritsu Megumi Garden Academy and addresses Unohana Chiyo as her teacher. The fallout from the Kujo family disaster also left Ryuko isolated: others feared that her Blood Manipulation resembled an Anomaly’s power and treated her as a dangerous omen. 19 773

By the time she met Su Youzi, Ryuko had become the feared leader of the Investigation Department’s Fourth Action Department. Her hatred of Anomalies, especially Iruka, kept her from falling fully into darkness, but also drove her toward the edge of an Anomalous state. 142 461

Appearance

Ryuko is a striking young woman with short black hair, scarlet eyes, and an intimidating presence that can make onlookers freeze or avoid meeting her gaze. Her combat attire is deliberately conspicuous and usually incorporates matte-black bodysuit stockings, an extremely short combat uniform, straps, and mismatched boots. 90 143 347

• Scarlet eyes that become especially frightening when she is angry or applying pressure. 19 347
• Usually wears protective black bodysuit stockings made from high-strength composite silk. 160 406
• Often carries or manifests her signature Blood Saw. 51 160
• Wears a dark-red Loyal Dog’s Collar given by Su Youzi; its chain has become a public symbol of her devotion. 90 174 348

Personality

Ryuko initially presents as paranoid, unstable, and sadistic. She openly states that she dislikes people and prefers dogs because dogs are obedient; she habitually views others as things to be commanded. Even so, she is capable of suppressing her cruel impulses when necessary. 19 22

Her outward severity masks deep trauma, resentment, and an intense fear of loss. She pursues Anomaly eradication with near-manic determination, particularly whenever Iruka or the Eye of Insight are involved. 142 461 496

Su Youzi fundamentally changes Ryuko’s behavior. Around outsiders, she remains a terrifying superintendent; around Youzi, she becomes embarrassed, obedient, affectionate, and dependent. She is fiercely protective of Youzi and repeatedly places Youzi’s safety above her own. 57 59 348

Abilities & Skills

Blood Manipulation

Ryuko’s Third Sequence ability allows her to control blood, particularly blood close to her own body or blood from living humans. 19 155

• Forms blades from dried bloodstains and can shape blood into weapons. 156
• Can turn a blood blade that has absorbed sufficient blood into a massive chainsaw-like Blood Saw. 160
• Uses blood to intercept splatter and protect allies during combat. 58
• Detects living beings through their heartbeats and flowing blood. 51 155
• Human blood is easiest for her to control; Anomaly blood, walking-corpse blood, and dried blood are substantially more difficult. 155
• Is severely disadvantaged against bloodless enemies and can exhaust herself by drawing too much of her own blood. 56

Blood Hounds

Blood Hounds are shadow-dwelling beasts derived from Ryuko’s ability. 20

• Guard targets and create a defensive perimeter around Youzi. 20 57
• Can bare their fangs against potential threats and protect incapacitated allies. 58
• May be unable to act effectively when Ryuko is disrupted by a powerful mental assault. 56

Deterrence

An Innate Ability acquired upon reaching the Third Sequence. 19

• Continuously places psychological pressure on nearby enemies.
• Makes affected targets more vulnerable to panic and fear of battle. 19

Combat Training

Ryuko is an executioner-style close-quarters combatant who favors overwhelming force and relentless pressure.

• Teaches Mixed Martial Arts fundamentals to Saotome Yukina. 29 33
• Fights effectively while surrounded, using Blood Hounds and wide-area blood weaponry. 51
• Can sustain major blood loss and continue attacking, though she is highly vulnerable to mental attacks due to her unstable mind. 160 419

Equipment / Weapons / Items

• Blood Saw — Ryuko’s signature chainsaw weapon, wielded during raids and against Chimeras. 51 56
• Loyal Dog’s Collar — A collar given by Su Youzi; it can serve as an emergency safeguard if Ryuko loses control in battle. 90
• Martyr’s Curse Necklace — An Evil Relic used to redirect damage from Kujo Iruka onto Ryuko during their confrontation; it exploded after Iruka’s attack. 421
• Kaimila composite-silk bodysuit — High-strength protective stockings comparable in durability to Lachiram Metal. 160 406

Relationships

• Su Youzi — Initially a mutually exploitative ally after Ryuko learns that the Eye of Insight is targeting Youzi. Ryuko becomes deeply attached to her, accepts Youzi’s collar, and prioritizes her safety above her own. 20 59 90 348
• Kujo Iruka — Her older sister, former idol, greatest source of hatred, and intended target. Their relationship gradually shifts from murderous resentment toward a tense, unconventional reconciliation. 18 418 573 729
• Hayabusa — Ryuko’s adjutant and emergency “control bolt.” Hayabusa uses Displacement to protect or evacuate Ryuko and remains devoted to her despite Ryuko’s volatility. 56 160
• Unohana Chiyo — Ryuko’s former teacher at Shiritsu Megumi Garden Academy. Ryuko addresses her respectfully as “Teacher.” 19
• Saion Sagara — A teacher whom Ryuko respects; Sagara entrusts her with investigating and destroying a Manifest Manufacturing laboratory. 142
• Soga Toyura — Initially viewed with hostility because of Ryuko’s belief that Toyura mistreated Su Youzi. 59
• Zero — Su Youzi’s pet and Ryuko’s rival for Youzi’s attention; Zero is hostile toward Ryuko, while Ryuko is jealous of Zero’s closeness to Youzi. 175
• Yarai Kenha — A senior who recommended Ryuko for leadership and helped establish the Fourth Action Department; Ryuko later grows suspicious of her connection to the Eye of Insight. 496

Story Role / Major Arcs

Eye of Insight Investigation

Ryuko identifies the Eye of Insight’s interest in Su Youzi and bluntly proposes using Youzi as bait to draw out cult operatives. Their early alliance begins as mutual exploitation, with Ryuko offering the protection of her Blood Hounds. 19 20

Taming by Su Youzi

After losing a wager and submitting to Youzi, Ryuko’s affection rises dramatically rather than collapsing as Youzi expected. Her growing attachment unlocks Youzi’s access to a portion of Ryuko’s Blood Manipulation and eventually culminates in Ryuko accepting the Loyal Dog’s Collar. 25 28 90

Sewer Chimera Incident

Ryuko infiltrates the Eye of Insight’s underground site, defeats walking corpses, and confronts a bloodless Chimera that directly counters her ability. Despite near-total blood depletion and mental attacks, she continues fighting to protect Youzi when Hayabusa’s Displacement accidentally transports Youzi into the battlefield. 51 56 57

Manifest Manufacturing Expedition

After receiving intelligence about a coastal Manifest Manufacturing laboratory experimenting on Abyssal Anomalies, Ryuko resolves to destroy it. During the expedition, she uses improved blood weaponry against walking corpses and joins Youzi in a pincer attack against the Chimera Leviathan. 142 156 160

Conflict with Kujo Iruka

Ryuko attacks Iruka out of long-held hatred, repeatedly returning to battle despite being severely injured and outclassed by Iruka’s Seventh Sequence power. She uses the Martyr’s Curse Necklace to protect Tsukuyomi Fuyu by redirecting Iruka’s damage onto herself. 418 419 421

Reconciliation and Forced Ascension

After Youzi orders her to make up with Iruka, Ryuko begins confronting the affection beneath her hatred. When Iruka attempts Forced Ascension, she entrusts Ryuko with a dagger to kill her if the process fails; Ryuko hesitates, ultimately trusting Iruka’s strength instead. 573 729 730
