Shinobu Kocho

Stinger Nichirin Katana: Shinobu wielded a heavily modified Nichirin Katana forged by Tecchin Tecchikawahara. It was the same as any katana from the handle to slightly above the hilt, but above that, the weapon loses its blade and was replaced by a rod. It ended in a needle-like tip, which resembled a traditional katana's in appearance and function. The blade was designed for injection of wisteria poison into demons, as Shinobu uses her medical expertise to replace her relative lack of strength and inability to decapitate demons. Her katana's tsuba was designed to bear resemblance to a butterfly, being four-petaled flower shaped that was in an aqua color with butterflies motifs, and trimmed with an orange border. The handle was orange and wrapped in crystal teal cords, and capped with an orange kashira. The blade was black in color, with the bottom hilt and the needle-like tip of the blade have a lavender-blue outline. The words Evil Demon (惡あっ鬼き, Akki?) was engraved on the right face, while the words Destruction (滅めっ殺さつ, Messatsu?) are engraved on the left face due her sword's structure. Along with her katana, she has also modified the weapon's sheath, using it as a portable poison mixer and loader. The sheath was in white with a butterfly motifs.

Butterfly Dance: Caprice (蝶ちょうノ舞まい　戯たわむれ, Chō no mai: Tawamure?)- The user leaps into the air and charges towards the opponent, stinging them multiple times with their blade to inject poison in just seemingly one strike.

Dance of the Bee Sting: True Flutter (蜂ほう牙がノ舞まい　真ま靡なびき, Hōga no mai: Manabiki?) - The user dashes at their target at blinding speeds and uses the momentum of their speed to then strengthen a single thrust into their opponent and inject poison into them.

Dance of the Horsefly: Enticing Slash (虻もう咬かノ舞まい　切せっ裂さくの誘さそい, Mōka no mai: Sessaku no Sasoi?) The user leaps off a vertical surface and unleashes a dashing thrust, before surrounding the opponent with numerous stabs like a horsefly, aiming to inject large doses of poison into different vital areas.

Dance of the Dragonfly: Compound Eye Hexagon (蜻せい蛉れいノ舞まい　複ふく眼がん六ろっ角かく, Seirei no mai: Fukugan Rokkaku?) - A six strike attack with which the user aims to strike and inject their target with multiple doses of poison at the target's weak spots (such as the neck, heart, torso, etc.) in order to kill them with a large dose of poison.

Dance of the Centipede: Hundred-Legged Zigzag (蜈ご蚣こうノ舞まい　百ひゃく足そく蛇じゃ腹ばら, Gokō no mai: Hyakusoku Jabara?) - An attack with which the user uses their full speed to run a zigzag pattern that confuses their opponent in order to create an opening for them to directly stab their opponent's neck and inject poison to kill them, with the stab's force and power being further enhanced by the momentum of their speed. Doma noted that the sheer speed of this technique was strong enough to destroy an entire wooden bridge.

Insect Breathing (蟲むしの呼こ吸きゅう, Mushi no kokyū?): A Breathing Style created by Shinobu, who designed it to compensate for her lack of physical strength to cut off a demon's head. Combined with the lethality of her poison, this Style allowed her to defeat countless demons.

Master Swordswoman: As a Hashira of the Demon Slayer Corps, Shinobu was one of the most powerful and skilled swordswomen in the entire organization. Her techniques were unique to her alone, but was as effective as any of the traditional swordsmanship styles. Her swordplay specialized in sword thrusting and piercing techniques in order to inject poison into demons. Her sword thrusts are so fast and powerful that they can pierce boulders and out-speed Water Breathing's Drop Ripple Thrust form, the fastest thrusting technique in that Breathing Style. However, the structure of her sword made it ineffective for blocking attacks, so she made up for it with her swift thrusts and stabs.

Enhanced Agility: Being a key aspect to her Insect Breathing swordsmanship style, Shinobu was incredibly agile and swift, shown when she maneuvered through a lush forest effortlessly. During fights, Shinobu relied on acrobatic movements to deliver dozens of short thrusts with her katana to inject as much poison as she could into her enemy at once. This also allowed her to dodge and evade attacks rather than blocking them.

Immense Speed & Reflexes: Shinobu possessed tremendous speed and reflexes enabling her to easily evade and out-pace demons, attacking them before they can even register what happened. She is said to be the fourth fastest runner among the Hashira.Shinobu was so fast that it often appears as if she teleported.

Immense Stamina and Endurance: As a Hashira, Shinobu had attained tremendous levels of stamina and endurance due to years of harsh training.

Enhanced Strength: Despite being the smallest member of the Demon Slayer Corps and thus having the weakest swinging strength due to her small arms, Shinobu instead displayed powerful thrusting and stabbing strength, as proven when she pierced a stone boulder in half and managed to break a ceiling with an upward thrust attack.

Indomitable Will: Shinobu possessed an undaunted spirit and incredible willpower, driven by her unyielding hatred for demons.

Keen Intellect: Shinobu was extremely intelligent and possessed keen observation and vast knowledge, to the point of being considered a genius.

Medical Expertise: Despite not being as combat-talented as the rest of her fellow Hashira, Shinobu instead displayed immense skill and mastery in over medical and pharmaceutical fields to make up for her lack of natural-born combat ability, being highly knowledgeable about how to create various poisons using wisteria and utilize them in combat to achieve the most deadly effect. She also possessed the medical skills needed to counteract the poisons and venoms created by demons. This was seen when she manages to undo the poison that was slowly transforming Zenitsu Agatsuma into a spider and restore him back to his previous human form.

Poisonous Physiology: Shinobu heavily altered her body by absorbing highly concentrated wisteria-based poison over a period of a year. She was successful in saturating her body with the undetectable poison that completely merged with her body's own cell structures, including those of her blood and internal organs—all the way down to the very tips of her fingernails. With her overall size and weight, her body became the equivalent of 37 kilograms worth of poison, approximately 700 times more than the lethal amount needed to kill an average demon. Shinobu saturated her entire body with poison without negatively impending her own health.

As a Hashira of the Demon Slayer Corps, Shinobu was a very powerful and skilled combatant. Despite not possessing the physical strength to cut off a demon's head common to that of an average Demon Slayer, she used her creativity, ingenuity and techniques to easily make up for it. Instead of the traditional method of decapitating a demon with a Nichirin Sword to kill them, she opted to use a modified version of a katana that acts as a stinger to inject a powerful wisteria-based poison that is lethal to demons. In addition to her intellect, she was extremely fast and agile, allowing her to overpower demons very quickly.

Shinobu also suffers from an inferiority complex due to her inferior physical abilities compared to her fellow Hashira, having been jealous of them for possessing taller or more muscular bodies than her and cursing her own body for not developing further to make her more effective in combat.

Shinobu's younger self had a more brash, blunt and uncomplicated demeanor as seen when she rescued Kanao Tsuyuri, whom she had a negative attitude towards raising at first. After the death of Kanae, however, Shinobu began to outwardly behave more like her older sister and eventually developed her gentle, positive attitude and mannerisms to match while internally holding in her rage, which she later clarifies was fueled by her desire to continuously display the smile that her sister loved. Though never shown onscreen, she has a notable temper, namely in the way that makes even the loud and brash Inosuke Hashibira take notice.

Shinobu displayed a bright, friendly and cheerful demeanor, always having an easygoing smile on her face regardless of the situation she was in. However, her outward behavior was shown very quickly to be a façade. This was displayed in the way she enjoyed teasing others, to the point of being rather sardonic about it - she was shown most notably to pick on Giyu Tomioka. Despite her relaxed exterior and her initial claim of wanting to get along with demons, she could be rather cruel towards them, which was seen when she killed Daughter after giving her false hope of helping her, and immediately attempting to kill Nezuko Kamado without giving her brother Tanjiro a chance to prove that she was harmless to humans. Later on, she was shown to have a more compassionate side towards the Kamado siblings after hearing their full story. She also showed to be very strict when she needed to, as she scolded Inosuke when he breaks the window.

It is later revealed that Shinobu's outwardly calm and tranquil disposition was worn as a mask, as she held an intense hatred for demons due to the loss of her beloved sister Kanae at a young age, along with the deaths of her parents, almost all of her Tsuguko, and the families of her apprentices at the Butterfly Mansion. This hatred was so strong that she was in a near-constant state of extreme anger, which was sensed by Tanjiro when the two held a conversation. Her desire for revenge rendered her unable to live the normal life her elder sister had wished upon her, instead devoting the entirety of her energy to defeating demons.

Over her uniform, she wore a distinctive white haori that once belonged to her late older sister, Kanae. The haori features a butterfly wing pattern inspired by the Monarch Butterfly, with a color gradient that fades from white into pale turquoise and then pink on the sleeves and hem, that are cuffed with a black trim, with pale turquoise dots, resembling butterfly wing edges. For footwear, she wore white zōri sandals with purple straps, and she conceals a hidden blade in the right sandal—used as a last resort weapon.

Height: 151 cm (4'11½ in) Weight: 37 kg (82 lb) Hair Color: Raven-Black to Purple Eye Color: Purple Her body measurements are Bust 86 cm; Waist 56 cm; Hips 86 cm. Shinobu was a petite, young woman of slender build and pale complexion, which sharply contrasts with her pink lips. She had large eyes that lack pupils, only a haze of gradient purple that blends with violet and dark purple with white highlights on the upper irises, making her eyes appear similar to those of insects. She had raven-black wavy hair that fades into a dark purple hue at the ends, styled at the back of her head into a flat yakai-maki bun fastened with a white butterfly ornament with a light purple rimmed, along with turquoise speckled spots. She had a center-split, ear-length, voluminous curtain bangs that flow down to frame the sides of her face, with two slightly thinner chin-length locks of hair in front of her ears below them. By the time of Hashira Training, both her bangs and locks are visibly more refined and slightly longer. She stood out among the more physically imposing Hashira due to her diminutive stature and small frame, which was later reinforced by her mentioning that she does not possess enough physical strength to decapitate a demon as the others do.

Shinobu wore a dark purple-tinted variation of the standard Demon Slayer uniform. It consists of a button-up jacket with a stand-up collar and long sleeves, featuring gold buttons and a shirt pocket on the left breast, with the kanji for Destroy (滅めつ, Metsu?) engraved on the back of the uniform. Beneath the jacket, she wore a white long-sleeved collared undershirt. Her long, saggy tattsuke-hakama pants are also tinted dark purple and are fastened at the waist with a white belt. Her legs were wrapped with a pair of unique white kyahan—with butterfly-patterned design—that fades from pale turquoise to pink gradient around the lower legs, and tied securely with white ribbons. Her tabi socks match the dark purple color of her uniform
