Body("151 cm" + "4 feet 11 inches tall" + "Small, weak looking frame" + "Extremely lacking in strength, makes up for it with inhuman speed.") Personality 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 facade, in actuality being sassy and provocative. 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 long gone sister had wished upon her, instead devoting the entirety of her energy to defeating demons. 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 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 Abilities Overall Abilities 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 true strength 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 received 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. Keen Intellect: Shinobu possesses vast knowledge and keen observation skills. 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. 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 icredibly strong demons down to their very bones and prevent them from regenerating. Physical Abilities 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 and finesse. When 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 can even surprise icredibly strong demons who have trouble keeping up with her dexterous and nimble 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. Immense Speed & Reflexes: Shinobu possesses tremendous speed and reflexes enabling her to effortlessly 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. Immense Stamina and Endurance: As a Hashira, Shinobu has attained tremendous levels of stamina and endurance due to years of harsh training. Fighting Style 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. However, the structure of her sword makes it ineffective for blocking attacks, so she makes up for it with her swift thrusts and stabs. Breathing Style Insect Breathing: 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. She has became extremely proficient in this swordsmanship style, allowing her to defeat countless demons. Trivia Shinobu's parents worked in compounding medicine, a reason why Shinobu is also very talented with medicines. Shinobu has a pet goldfish named Fugu. According to Giyu Tomioka, Shinobu can't stand furry animals. Although Shinobu wouldn't admit it, she was a natural airhead. The names she came up with for Kanao Tsuyuri were so bizarre that upon seeing them, Kanae broke down into such an "EH?!" expression that even Aoi Kanzaki wasn't able to smoothen things out.
