Riyou Reaper

Riyo is a teenage girl with an extremely slender build and pale skin. She stands at 155 cm (5'1") — a measurement she supplements with 10 cm boots at all times, bringing her to 165 cm. She has long, messy red hair typically tied up in a sidewards loop that is notably shaped like scissors — an unintentional or deliberate visual echo of her Vital Instrument. Her eyes are a vivid green with a distinctive star or cross pattern in the pupils. She has long eyelashes, short-cropped eyebrows, and three small vertical lines beneath each eye as under-eye markings.

Her standard Cleaners outfit consists of a white sleeveless crop top framed by black harnesses, worn under an oversized Cleaners jacket left open to expose her torso, with the Cleaners' logo stamped on the right sleeve. She wears dark shorts secured by a large white belt holding two knapsacks — one on her back containing her respirator (Full Face), and one on her right thigh holding The Ripper. She wears long thigh-high stockings.

The Doll Festival Outfit

For the Doll Festival, Riyo wore a dark shirt under a long-sleeved light grey jacket with a large collar and a red bowtie. She paired it with teal shorts, dark leggings with spiral patterns, and her standard heavy-soled boots. The outfit reflected her personality in its combination of contrasting tones — not exactly formal, not exactly casual, distinctly her.

Riyo has a strong sense of justice and operates with a carefree, free-spirited mindset that remains largely intact even when facing opponents she has no obvious reason to be relaxed about. She is childish in specific ways, energetic in most ways, and has bad manners in the precise sense that she does not observe social conventions that she finds functionally unnecessary. The author, Kei Urana, intended to create a "decent" character and described Riyo as turning into a "freaky weirdo" during the drawing process. That characterisation is affectionate and accurate.

Fired Up by Challenges

Riyo gets excited at the prospect of a strong opponent in a way that the series presents as genuine rather than performative. A difficult fight does not alarm her — it activates her. She remains calm and free-spirited even in situations that would reasonably produce stress, because she is the kind of person who reads "hard fight" as interesting information rather than as a problem to be afraid of. This quality is not invulnerability. She got thrown from a Trash Beast and broke her spine. She was still cheerful about it in the infirmary.

The Vow and What It Costs

Beneath the cheerful exterior is a person who made a specific and binding promise: she will never use her scissors to kill a human again. This is not a rule imposed on her by Enjin that she resents. It is a commitment she chose, framed as a personal line she will not cross. In fights against human opponents, this means she falls back on a handgun — a non-Anima weapon, a reminder of where she came from — to neutralise threats without breaking her vow. The constraint is visible in how she fights Raiders. She wins. She just wins differently than she could.

Protective Instinct

She is fiercely protective of her "juniors" — Rudo specifically. When she was hospitalised after the Penta fall, she maintained her composure specifically to prevent Rudo from blaming himself for her injuries. The protective instinct is not expressed through hovering or over-explanation. It is expressed through continuing to be Riyo in front of him when it would have been easier not to.

Specific Preferences

She loves spicy food and has a documented, slightly eccentric fascination with hair — a trait the series notes and that she does not explain. She dislikes sweet food, cockroaches, and being included in photographs. She is self-conscious enough about her height to wear 10 cm soles without exception. She calls Rudo a "weird kid" and a "turd" with equal affection.

Riyo was raised and trained as a professional contract killer. The specifics of how she entered that life — who trained her, why, or under what circumstances — are not disclosed. What is established: she was good at it, she used both her scissors and firearms in that capacity, and at some point she chose to leave.

The departure from her former life came with a single parting gesture from her old boss: a handgun, given as a gift. She still carries it. She does not use it as a Vital Instrument. It is a non-Anima weapon that sits on her belt as a functional tool and as a quiet acknowledgment that where she came from and where she is now are not entirely separate — the same hands that committed violence are now deployed in the Cleaners, under different terms.

She joined the Cleaners — specifically Team Akuta — at some point before Zanka Nijiku, which makes her the senior member between the two. Enjin established the condition of her membership as a prohibition on killing humans again. She accepted it and held to it. The scissors she now uses against Trash Beasts were once, by her own description, stained with blood. She intends never to use them that way again.

Her father is a point of mystery. Mymo identified him as a psychological target during the Doll Festival arc — asking "How is your father doing?" as deliberate psychological warfare — suggesting there is something significant about that relationship that Riyo has not disclosed. The full context of that vulnerability has not been revealed.

Introduction — Rudo's First Mission

Riyo's introduction happened when Rudo was overwhelmed by a Trash Beast swarm on his first active mission. She intervened, shredded through multiple enemies using The Ripper with her feet, and then demonstrated the technical depth of her approach: she explained that Trash Beasts must be cut until you reach the core object — in this case, a discarded brush pen from Canvas Town — and that object must be stabbed to end the fight. She called Rudo a "weird kid." She also saved his life. The dynamic was established immediately: veteran detachment with an underlying warmth that she does not name.

Penta Arc — Noerde and the Fall

Intercepted during the Penta mission by the Raider Noerde Hew Amazo — who used electrified hair manipulation and called her "kitten" — Riyo found herself at a tactical disadvantage against an opponent whose power countered her scissors effectively. She stated her vow directly: "fighting other people isn't really my thing" — and then finished the fight using her handgun rather than The Ripper, landing precise non-lethal shots while injured.

Shortly after, she was thrown from a jumbo Trash Beast. The result: a broken spine, broken ribs, and severe internal damage. She was rushed to the infirmary. Rudo felt immense guilt. From her hospital bed, she told him: "Don't bury me too soon... I'm still alive and kicking." She meant it as comfort, and it was.

The Doll Festival Arc — Return and Mymo

Riyo returned to active duty during Mymo's South Ward takeover before she was fully healed. Mymo deployed his most targeted psychological weapon against her mid-conflict: "How is your father doing?" — a question that visibly shook her and confirmed the existence of a familial wound the series has not yet explored fully. She did not break. She coordinated with Zanka to engage Mymo's Apostle form, targeting his sympathetic nervous system with a joint assault. Mymo called their efforts "minor." Both of them kept fighting.

Vital Instrument — The Ripper (Giant Scissors)

Riyo's Jinki is The Ripper — a pair of giant ornate scissors that she holsters on her right thigh and wields primarily with her feet. When activated, her Anima allows her to "cut and cut" through the physical and spiritual components of Trash Beasts until she reaches the core object — the discarded item from which the Beast was formed — which she then stabs to end the fight. Enjin describes her extermination method as "logical": she works through a Beast systematically until she finds what she is looking for, then ends it. It is the most methodical description available for a fighting style that looks completely chaotic from the outside.

Foot-Based Combat — Peerless Dexterity

Riyo's defining technical skill is wielding The Ripper primarily with her feet — performing complex, high-precision manoeuvres with her lower body that most Givers can only manage with their hands. This keeps both hands free for balance, secondary tools, or her handgun. Enjin noted that using scissors with feet is "not something to do in polite company," which is as close as the series gets to describing it as unusual — because it is also undeniably effective. She can shred multiple Trash Beasts simultaneously, slice through high-speed projectiles, and maintain acrobatic mobility across the battlefield while keeping the scissors in continuous motion.

Marksmanship — The Parting Gift

Riyo carries a non-Anima handgun from her former boss — a parting gift from her contract killer days, never used as a Vital Instrument, kept specifically for situations where her vow requires her not to use The Ripper. She is a crack shot: in the Noerde fight, she landed precise non-lethal hits while injured, under pressure, against an opponent who had been countering her scissors effectively. The gun represents the specific intersection of her past and her present — the same marksmanship that served her former life, now deployed under a constraint that was her own choice.

Speed and Physical Capability

She is described as fast even by elite Raider standards — capable of moving across a battlefield with acrobatic ease, slicing through high-speed ballistics without apparent difficulty, and maintaining functional combat operations after a broken spine had removed her from active duty. Her physical vulnerability shows up in environmental hazards and high-impact falls rather than in direct combat exchanges.

Riyo vs. Trash Beast Swarm — Introduction

Riyo's introduction as a combatant. She intervened when Rudo was overwhelmed on his first mission, demonstrating The Ripper's foot-handling style against multiple targets simultaneously. The battle included a larger, multi-limbed Trash Beast that she had to cut through layer by layer until she found its core — a discarded brush pen from Canvas Town — which she stabbed to end the fight. The encounter established her combat method and her relationship with Rudo in the same sequence.

Riyo vs. Bundus Beggalcate — Border Ambush

During the team's initial mission to the Border, the Raiders ambushed them and Bundus engaged Riyo with his mechanical Hand Number 6 — a multi-fingered prosthetic apparatus with Anima quality significantly above standard Jinki. Despite her speed, she was countered and overwhelmed. The encounter confirmed that Riyo's speed-based style can be neutralised by a veteran who has the mass and arm quality to intercept it, and that the gap between Cleaner-level and Raider-veteran-level remained significant at that point in the story.

Riyo vs. Noerde Hew Amazo — Penta

Riyo's most revealing fight. Noerde's electrified hair manipulation countered The Ripper effectively, called Riyo "kitten," and placed her at a genuine tactical disadvantage. Riyo explicitly stated her vow — "fighting other people isn't really my thing" — and then ended the fight by reaching for the handgun instead. Precise non-lethal shots from a former professional marksman closed the gap that The Ripper could not. She proved her marksmanship, confirmed her past, and maintained her promise simultaneously. The fight also left her vulnerable — shortly after, the fall from the Trash Beast hospitalised her with a broken spine and ribs.

Riyo & Zanka vs. Mymo (Apostle Form) — Doll Festival

Riyo and Zanka coordinated precision strikes against Mymo's sympathetic nervous system — technically accurate attacks that should have had meaningful effect on any standard biological opponent. Against a body reconstructed through a Watchman Series pendant, they were absorbed and dismissed. Mymo also used the fight to deploy psychological warfare, asking Riyo about her father — a calculated probe that landed. She did not break her engagement. The battle's significance is less in its outcome than in what it demonstrated: the ceiling of what elite Cleaners can achieve against Watchman-level power, and the specific personal cost Riyo paid for being present.

• Riyo's birthday is April 9th — placing her under Aries, a zodiac sign associated with boldness, direct action, and an impulsive willingness to engage challenges without overthinking them. The alignment with her character is near-perfect.
• In the anime adaptation (Studio Bones, 2025), Riyo is voiced by Yumiri Hanamori (Japanese) and Katie Caruso (English). Hanamori is known for playing Ai Hayasaka in Kaguya-sama: Love Is War and Nadeshiko Kagamihara in Laid-Back Camp. She was one of the first characters to receive an official character PV ahead of the series premiere.
• Author Kei Urana stated that she originally intended to create a "decent" character with Riyo but that during the drawing process, Riyo turned into a "freaky weirdo." The description is affectionate and was confirmed by Urana herself.
• Her hair, when tied up, forms a sidewards loop that is notably shaped like scissors — a visual echo of her Vital Instrument that is either deliberate character design or a coincidence that the series decided to acknowledge. Either way, it is accurate.
• She is self-conscious enough about her height to wear 10 cm platform boots without exception — adding them to her official height stat in her own profile, as a formal declaration rather than an oversight.
• She has a documented fascination with hair — a preference the series notes and attributes to her without explanation. Whether this connects to her scissors, her aesthetic sensibility, or something else entirely has not been addressed.
• She is the only member of Team Akuta shown to have a strong aversion to being in photographs. Given her former life as a professional killer, the aversion to documented visual records is probably not a coincidence, but the series presents it without commentary.
• The handgun she carries was a parting gift from her former boss in the assassination underworld. She does not use it as a Vital Instrument. It is a non-Anima weapon she has carried since leaving that life — the most direct visual link between who she was and who she is, sitting on her belt every mission, used only when her vow requires it.
• Riyo joined the Cleaners before Zanka Nijiku, making her the senior between the two — a seniority she exercises primarily through teasing him about his inferiority complex, which may be the most efficient way available to erode it.
• Her scissors — The Ripper — represent the "cutting" of ties with her murderous past to become a Cleaner of the world's trash. The symbolism is the most deliberate naming decision in her profile and is presented by the series without irony.
