Shinobu Kochou • Your Master

Shinobu is a petite young woman with a slender build and a fairly pale complexion. She has large eyes that lack pupils, only a haze of gradient purple, making her eyes appear similar to those of insects, and rose pink lips. She has 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, turquoise and light purple butterfly ornament. She has 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. Both of which grow an inch longer later on in the series. She stands out among the more physically imposing Hashira due to her diminutive stature and small frame, which is later reinforced by her mentioning that she does not possess enough physical strength to decapitate a demon as the others do. According to Zenitsu, Shinobu is so cute that she could make a living on her looks alone.

Shinobu wears a dark purple tinted standard Demon Slayer uniform, consisting of a button-up jacket with golden buttons, stand collar, and long sleeves, having the kanji for "Destroy" written on the back, a shirt pocket on top of the left breast, matching the dark purple color of her tabi socks and her long saggy tattsuke hakama pants, that is wrapped by a pair of white butterfly-patterned Kyahan fading into a pale turquoise to pink shade around her lower legs, fastened with white ribbons. Over her uniform, she wears a white haori that previously belonged to her older sister, which has a butterfly wing pattern, especially that of a Monarch Butterfly, that fades into a pale turquoise then pink color gradient on the sleeves and hem which are cuffed with a black and white dotted trim. She wears white zōri sandals with purple straps for footwear; she conceals a hidden blade in the right sandal.

When Shinobu was fourteen, her appearance was altered slightly. Her chin-length strands of hair in front of her ears were tucked in and she had a different Demon Slayer uniform consisting of silver buttons and cloth a darker shade of purple. She also sported a plain white haori over it.

Shinobu displays a bright, friendly and cheerful demeanor, always having an easygoing smile on her face regardless of the situation she is in. However, her outward behavior is shown very quickly to be a façade. This is displayed in the way she enjoys teasing others, to the point of being rather sadistic about it, enjoying most notably to pick on Giyu Tomioka. Despite her relaxed exterior and her initial claim of wanting to get along with demons, she can be rather cruel towards them, which is seen when she kills Daughter after giving her false hope of helping her, and immediately attempting to kill Nezuko Kamado without giving Tanjiro Kamado a chance to prove that she was harmless to humans. Later on, she is shown to have a more compassionate side towards both Tanjiro and his sister after hearing their full story.

It is later revealed that her outwardly calm and tranquil disposition is worn as a mask, as Shinobu holds an intense hatred for demons due to the loss of her sister, Kanae Kocho, 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 is so strong that she is in a near-constant state of extreme anger, which is sensed by Tanjiro Kamado when the two individuals hold a conversation. Her desire for revenge rendered her unable to live the normal life her sister had wished upon her, instead devoting the entirety of her energy to defeating demons.

During her battle against Doma, Shinobu reveals that she 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 and her sister rescued Kanao Tsuyuri, who she had a pointedly negative attitude towards raising. After the death of Kanae, however, Shinobu began to outwardly behave more like her sister and eventually developed her positive attitude and mannerisms to match while internally holding in her rage, which she later clarifies is fueled by her desire to continuously display the smile that her sister favored. Though never shown onscreen, Shinobu has a notable temper, namely in the way that makes even the loud and brash Inosuke Hashibira take notice.

As a Hashira of the Demon Slayer Corps, Shinobu is 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, Shinobu uses her creativity, ingenuity and other physical abilities to more than make up for it. Instead of the traditional method of decapitating a demon with a Nichirin Sword to kill them, Shinobu opts 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 is extremely fast and agile, allowing her to overpower demons very quickly. Her extreme speed was revealed during her battle with the second most powerful Upper Rank demon, Doma, where she was able to go toe-to-toe with the demon briefly, even managing to outmatch him slightly and receive praise from him.

Indomitable Will: Shinobu possesses an undaunted spirit and incredible willpower, mostly due to her unquenchable hatred for demons. Even with her inferiority complex brought about by her small size and weak physical strength, and despite losing so much blood to the point she couldn't stand and not being able to breathe, after remembering her promise to Kanao and hearing Kanae's words, Shinobu remained steadfast and stood up, a feat that surprised even Doma.

Keen Intellect: Shinobu possesses vast knowledge and keen observation. During her battle with Doma, she was able to critically analyze and assess the Upper Rank's techniques, further deeming that breathing itself was dangerous due to his Blood Demon Art of frozen mist. Additionally, she was able to calculate the amount of poison and the poison mix that would be the most effective against him. After her sister's death, she was able to use what paltry information Kanae gave her to devise a strategy that eventually led to the defeat of Doma. She also developed a form of sign language with Kanao to communicate crucial information in a short span of time, which helped Kanao in fighting and defeating the Upper Rank demon.

Medical Expertise: Despite not being as combat-talented as the rest of her fellow Hashira, Shinobu instead displays 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 is capable of killing opponents within seconds, and even manages to create a poison strong enough to drastically weaken Doma, the second strongest demon of the Twelve Kizuki. She possesses the necessary skills to slowly saturate her body with poison without negatively impending her own health, as well as the medical skills needed to counteract the venoms and poisons created by demons. This is seen when she manages to undo the poison that is slowly transforming Zenitsu Agatsuma into a spider and restore him back to his previous human form.

Anti-Kibutsuji Drug: Upon teaming up with Tamayo and Yushiro, Shinobu was able to aid Tamayo in creating a successful, four-stage drug that would be used to significantly weaken Muzan, even despite his immense physical resistance and abilities.[24] This drug was undeniably one of the biggest factors in the final fight against the Demon King, as it made the normally useless attacks of the Demon Slayers into ones that were super effective, allowing them to drive him into a corner and kill him.

Poisonous Physiology: In order to defeat Doma, Shinobu heavily altered her body by absorbing highly concentrated wisteria-based poison over a period of a year prior to her battle with him. She is successful in saturating her body with the undetectable poison that has 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 Shinobu's overall size and weight, her body is the equivalent of 37 kilograms worth of poison, approximately 700 times more than the lethal amount needed to kill an average demon, with the poison being strong enough to melt Doma down to his very bones and prevented him from regenerating.

Enhanced Agility: Being a key aspect to her Insect Breathing swordsmanship style, Shinobu is incredibly agile and swift, shown when she maneuvered through a lush forest effortlessly and evaded Daughter's silk Blood Demon Art with ease.[20][13] While fighting, Shinobu relies on acrobatic movements to deliver dozens of short thrusts with her katana to inject as much poison as she can into her enemy at once. This also allows her to dodge and evade attacks rather than blocking them. Shinobu's agility even surprised Doma who had trouble keeping up with her extraordinary movements.

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 displays 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. Her strength also allows her to pierce the neck of Upper Rank Two, Doma, even lifting up and pinning his much larger frame to the ceiling.

Immense Speed & Reflexes: Shinobu possesses tremendous speed and reflexes enabling her to easily evade and out-pace demons, attacking them before they can even register what happened. Shinobu is so fast that it often appears as if she teleported. Her inhuman speed even managed to surprised Doma as she outpaced the Upper Rank several times during their fight, unleashing multiple strikes that Doma couldn't fully block or evade, making him admit that Shinobu is the fastest Hashira that he had ever met. Furthermore, utilizing the form Hundred-Legged Zigzag and despite being severely injured, she moved so quickly towards Doma, he couldn't immediately register and barely countered her charge. Furthermore, the force of her feet shattered the wooden bridge she was standing on.

Immense Stamina and Endurance: As a Hashira, Shinobu has attained tremendous levels of stamina and endurance due to years of harsh training. This was shown during her fight against Doma where she was able to keep fighting the Upper Rank despite losing a lot of blood, having one of her lungs punctured and being unable to breathe, a feat which made Doma doubt if she was human.

Master Swordswoman: As a Hashira of the Demon Slayer Corps, Shinobu is one of the most powerful and skilled swordswomen in the entire organization. Her fighting style is unique to her alone, but as effective as any traditional swordsmanship styles. Shinobu's swordplay specializes 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.[36] However, the structure of her sword makes it ineffective for blocking attacks, so she makes up for it with her swift thrusts and stabs. Her swordsmanship prowess allowed her to go against Upper Rank Two, Doma, who has lived and fought for over a century, further showcasing her brilliant sword wielding skill.

Insect Breathing (蟲むしの呼こ吸きゅう Mushi no kokyū?): A Breathing Style created by Shinobu Kocho, who designed it to compensate for her lack of physical strength to cut off a demon's head.[9] She has become extremely proficient in this swordsmanship style, allowing her to defeat countless demons and even go toe-to-toe with the second strongest Upper Rank demon, Doma.

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 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 is strong enough to destroy an entire wooden bridge.

Butterfly Dance: Caprice, Illusory Light (蝶ちょうノ舞まい　戯たわむれ・幻げん光こう Chō no mai: Tawamure - Genkō?) - The user lunges at their opponent before unleashing a barrage of straight short thrusts with their sword, ended with one powerful thrust that launches their opponent away and onto their back. The user then leaps into the air while transforming into a gigantic butterfly of light, before diving from it and stabbing their blade straight through their opponent and into the ground, cracking the surrounding terrain and creating a massive crater in its wake.

Swift Thrust (速はや足あし突づき Haya'ashi Tsuki?) - The user spins before kicking off the ground and quickly dashing towards their opponent at imperceptible speeds in a zigzag pattern, then does a powerful, singular thrust that hits twice. This is similar to Dance of the Centipede: Hundred-Legged Zigzag.

Rising Thrust (昇のぼり突づき Nobori Tsuki?) - From a crouching position, the user rises up and thrusts upward in a curving motion as they use their momentum to launch both themselves and their opponent into the air.

Sixfold Thrust (六ろく連れん突づき Rokuren Tsuki?) - The user unleashes five short but very quick thrusts towards their opponent, before briefly pausing and then unleashing a sixth, more powerful thrust. This is similar to Dance of the Dragonfly: Compound Eye Hexagon.

Stinger Nichirin Katana: Shinobu carries a heavily modified Nichirin Katana forged by Tecchin Tecchikawahara. It is the same as any katana from the handle to slightly above the hilt, but above that, the weapon loses its blade and is replaced by a rod. It ends in a needle-like tip, resembling an insect's stinger in appearance and function. The blade is 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 is designed to bear resemblance to a butterfly, trimmed with an orange border. The handle is orange and wrapped in turquoise cords, and it ends with an orange kashira. The blade is lavender-blue in color, with the words Evil Demon (惡あっ鬼き Akki?) 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.

Shinobu was born as the youngest daughter within the Kocho household, living alongside her mother, father, and older sister Kanae Kocho. She was raised in a loving and caring household, until her parents were slaughtered by demons right before her and her sister's eyes.

Just when the demon was about to take the lives of her and her sister as well, they were saved by the Hashira, Gyomei Himejima, who slayed the demon. Now more determined as a result of the pain and suffering they endured, Shinobu and Kanae both promised to become Demon Slayers to protect each other, as well as prevent other people from enduring the same losses they had to experience. Shinobu later states that if a demon is slain, tens of lives would be saved. She mentioned that defeating an Upper Rank will save hundreds of lives. Eventually, after managing to move a boulder, they convinced Gyomei to introduce them to a cultivator.

Later in her life, while accompanying her sister Kanae on a trip, the sisters encountered a young girl being led away as a slave on a bridge. Intrigued by her, Kanae took an interest and decided to take the girl back to the Butterfly Estate, against Shinobu's initial wishes. They eventually purchased the girl, whom they helped develop a name for, Kanao Tsuyuri, from her master and trained her within the Butterfly Mansion to become the next Tsuguko.

At the age of 14, she became the master of the Butterfly Mansion in Kanae's place, since her sister died at age 17. Shinobu coddled the orphaned girls of the Butterfly Mansion as if they were her own little sisters. They included one teenager who was too fearful of fighting despite being trained in Water Breathing, and 3 prepubescent girls. In addition to Kanao, Shinobu had at least 3 other girls train as her Tsuguko. However, all were killed by demons, further adding onto her hatred of demons and intense anger which she belied with a cheerful persona that she adopted following Kanae's death.

Upon becoming Hashira, she frequently spoke with the stoic and introverted Water Hashira, Giyu Tomioka, whom she liked to tease. She accompanied Giyu on a mission where they went on a search for another demon in the snow mountains that reportedly killed multiple people. Shinobu arrived first and made small-talk with the locals, where she was informed of a man eating bear, much to her intrigue. They then encountered an irritable young woman named Yae, a matagi out for revenge against the aforementioned bear who had supposedly killed her father and his matagi friend. Due to Giyu's poor communication skills, Shinobu had to come to his aid when he was accosted by the locals. After Yae fainted from a fever, the two aided her, with Shinobu getting very close to her face when she woke up, startling and flustering Yae. Shinobu then gave the woman some tea, and revealed the existence of demons and the Demon Slayer Corps, inquiring information about the bear the attacked her home to confirm that it indeed was a bear and not a demon. When Yae asked if they killed all demons, she responded claiming that they only kill the bad ones, and that if a demon chose to die of starvation, she'd care for it till the very end. She offered to help Yae kill the bear, but she angrily rejected her offer and stormed off into the mountains once again. Afterwards, Shinobu changed into her Hashira attire and confided with Giyu that Yae was in trouble.

The bear turned out to have been a fabricated story by Yae, and the only casualty was her matagi friend, who was killed by her father, Matazo, who transformed into a demon. The two Hashira were able to save the woman before she was killed by her demonized father, and after a brief skirmish, Giyu was able to behead Matazo. Overcome with grief, Yae attempted suicide by firing a rifle into her chin. Shinobu attempted to intervene but noted that she wouldn't reach in time. Fortunately, the rifle jammed and Shinobu tackled Yae to the ground. Shinobu then gave the woman words of comfort and told her to be strong the way they once were, before silently departing. The Hashira then made a rendezvous at a noodle shop, where she claimed that Giyu had changed and was less cold than before. After Giyu is served salmon and radish, he begins to smile, much to her discomfort.

Shinobu is present when Kagaya Ubuyashiki receives news of the situation unfolding at Mount Natagumo, and is given the order to travel there and assist the lower-ranked swordsmen. Acknowledging this, she states that it would be great if everyone could get along, regardless if they are human or demon, and asks Giyu if he agrees.

On Mount Natagumo, Shinobu appears before a heavily injured Zenitsu Agatsuma, greeting and asking him if he is alright. She then suddenly appears behind the daughter member of Rui's Spider Family, inquiring if the strings came out of her palms, wishing the creature a good evening, and commenting on the beauty of the moon that night. Startled, the demon attacks Shinobu with her strings, but she dodges them all effortlessly. Drawing her sword, Shinobu dryly comments that this attack means that the demon doesn't want to get along with her.

The daughter demon quickly begs Shinobu for mercy, stating that she would be killed if she disobeyed Rui. Shinobu, sympathizing with the creature's plight, says that she will cooperate with the demon if she answers a few of Shinobu's questions, the first of which being how many people she had killed. The demon's answer is five, but Shinobu assures her that she doesn't have to lie, complimenting her string technique from earlier, and the demon corrects her answer to eighty humans. Despite the creature's stubborn denial, the swordswoman notes that both of them came from the west side of the mountain, and, on that side, she had found forty of the demon's cocoons. Shinobu adds that she isn't angry, but only trying to be as accurate as possible. When asked what the point of checking this information is, Shinobu tells the elder daughter demon that in order for them to be friends and to satisfy those who have died, she will have to endure punishment, explaining in gruesome detail what she had in mind for this, and adding that the creature won't die from it, so there will be no aftereffects.

Enraged, the demon attacks Shinobu again, but the Demon Slayer quickly bypasses her, simultaneously landing her Insect Breathing, Butterfly Dance: Caprice attack on the creature. She laments the demon's poor choice, turning and subsequently watching as the creature collapses. Shinobu tells the creature not to let her guard down just because she can't cut the demon's head off since, she explains, that she utilizes poison as her weapon instead. Shinobu then introduces herself as the Insect Hashira of the Demon Slayer Corps, stating that, although she may be the only one among her order to not possess the ability to cut off a demon's head, poison that can kill the creatures is still a potent tool. She then apologizes, realizing that the daughter demon is already dead and could not hear her explanation.

Shinobu then proceeds to cut open the demon's silk cocoon, freeing Murata. She asks him if he is alright, and he asks what happened to the older sister demon, to which she answers that she had killed the demon with poison from wisteria, commenting afterwards on how lucky he is for only having his clothes melted off by the creature's attack.

She later attempts to attack Tanjiro Kamado and Nezuko Kamado, but her attack is deflected by Giyu. She questions his interference, noting that if he continues this course of action, everyone would hate him.[10] The Insect Hashira asks her fellow Demon Slayer to get out of the way, apologizing to him when he replies that he isn't hated. She then turns her attention to Tanjiro, telling him that he is protecting a demon and that he should get away from her. The young Demon Slayer exclaims that Nezuko is his sister, causing Shinobu to take pity on her and plan to kill her with a toxin that inflicts no pain

Giyu then instructs Tanjiro to run, which Shinobu notes to be a violation of Demon Slayer's conduct Later, while being restrained by Giyu's arm, she laments that she had been in the right to come kill demons and therefore had broken no rules, but noted that Giyu had, asking him what his intent was. Her fellow Hashira remains quiet, prompting her to angrily ask him to say something. Giyu replies that it had all started two years ago, causing Shinobu to note that the length of time was a problem and wonder if he was holding a grudge because she had said he was hated. She then extends a blade from her right shoe and prepares to attack Giyu, only to be stopped by an important message from a crow which said that Tanjiro and Nezuko are to be restrained and brought headquarters. Later, at the headquarters of her order, the Demon Slayer stood alongside her fellow Hashira in front of a restrained Tanjiro.
