Shinobu Kocho(Japanese:
Shinobu Kocho is the Insect Hashira, one of the nine Hashira of the Demon Slayer Corps. She hasfair skinand violet eyes[4], and has a slender build. She wears a blue-purple butterfly hair clip year-round, and when her yakaimaki bun is undoneher hair reaches approximately to her collarbone. Over her Demon Slayer uniform, she wears a haori with a butterfly wing pattern, which is her late sisterKanae Kocho's memento. Her appearance is cute and dignified; according to Zenitsu, she is a beauty who could live off her looks until old age[5]. She is also specifically mentioned in the official guidebook as a woman with exceptionally outstanding looks.
She is, aside from the Mist HashiraMuichiro Tokito, the youngest among the Hashira, yet many readers call her Big Sister Shinobu. Among the current nine Hashira, she is the shortest and lightest[6]。
Always smiling and cheerfulForcing a smile,Only when fightingUpper Rank TwowhenHad her composure break,Her personality is gentle and reserved. Before Kanae's death, Shinobu was more outspoken, competitive, and easily angered than she is now; after her sister's passing, she strove to become as gentle as her sister was. But even though she often has a smile on her face, she has always suppressed her anger toward demons. When she finds it difficult to suppress her anger, Shinobu demands of herself that "being unable to control one's emotions is a sign of immaturity" and tries to calm down as much as possible.
Her attacks are characterized by speed and thrusts, and she is the only swordsman in the Demon Slayer Corps who cannot decapitate a demon with her own strength. She felt inferior because her strength was insufficient to cut off a demon's neck, and even after attaining the strength of a Hashira, she could never rid herself of that thought. Her Nichirin Sword has a slender blade with a barb at the tip, forged by Tecchin Tecchikawahara, the chief of the Swordsmith Village; the sword is designed to store toxins and can dispense them as needed[7]. The toxin composition can be changed when the sword is sheathed. Shinobu also has a small knife hidden in the sole of her shoe to defend against enemies in case her hands are pinned,in the manga, onlyGiyu Tomiokaalmost got stabbed。
Born into a family of pharmacists, Shinobu is proficient in pharmacology and toxicology. She is not only skilled at using Wisteria poison to kill demons but also manages the Demon Slayer Corps' medical facility, the "Butterfly Mansion." In terms of pharmacy, she can prescribe medicine to further heal toxins caused by Blood Demon Arts, such as treating the muscle-degenerating poison of the Elder Brother Spider Demon andGyutarothe poison of the Blood Sickles, etc.
Their parents were killed by a demon, and the young Kocho sisters were on the verge of being victimized when they were saved by the Stone Hashira of the Demon Slayer Corps,Gyomei Himejima. Gyomei had the Demon Slayer Corps' cleanup unit, the "Kakushi," take the two to a relative's house. After handling their parents' funeral, the two promised to slay demons together to protect the happiness of others that had not yet been destroyed by demons.
Half a month later, the Kocho sisters found Gyomei Himejima through the "Kakushi" and asked him for guidance on how to hunt demons. Initially, Gyomei refused, believing that he should not deprive these children of their future based on momentary emotions, and urged them to live as ordinary people. However, he was eventually moved by their perseverance and introduced them to Cultivators. On the morning after receiving Gyomei's promise, the sisters set out for their respective Cultivators, underwent training, and survived the "Final Selection" on "Mt. Fujikasane," tearfully fulfilling the reunion they had promised years ago.
One day, the Kocho sisters rescued from a slave trader agirl, and brought her back to the Butterfly Mansion to raise. Noticing that she was completely unable to make decisions, Kanae taught her the method of flipping a coin to decide, which Shinobu criticized for being too arbitrary.
When Shinobu was 14 years old, Kanae, as the Flower Hashira, encountered Upper Rank Two,DomaDoma. When Shinobu arrived at the scene as reinforcements after sunrise, Kanae's injuries were too severe to be treated. Although she pleaded with Shinobu on her deathbed to leave the Demon Slayer Corps and find happiness like an ordinary girl, Shinobu did not agree. Kanae helplessly described the killer's characteristics and passed away with words left unspoken.
At Kanae's funeral, Shinobu noticed that Kanao wanted to cry but couldn't due to psychological trauma; understanding her true feelings, Shinobu comforted her. After the funeral, Shinobu Kocho took her late sister's place as the master of the Butterfly Mansion.
Later, after undergoing rigorous training, Shinobu became the Demon Slayer Corps'Insect Hashira.。
When Shinobu was 16, she traveled to a northern post town to purchase raw medicine. There, she heard rumors of a man-eating bear from an old woman at a pharmacy and witnessed a dispute between Yae, a hunter's daughter and survivor of a "bear" attack, and other hunters.
Giyu Tomioka, the Water Hashira who had arrived to carry out a mission, had been spotted near the scene where a charcoal burner's family was brutally murdered in the neighboring mountains. Due to his poor communication skills, he was nearly tied up and taken to the police station as a suspect. Unable to just watch, Shinobu stepped in to explain. Although she wanted to point out that Giyu was misunderstood by his peers because of his lack of words, she gave up upon seeing he had no self-awareness of the matter.
The two then took the feverish and unconscious Yae to the pharmacy to be cared for. During a conversation with Yae after she woke up, Shinobu sensed that she was intentionally hiding facts related to demons. After Yae left, Shinobu changed into her uniform and headed into the mountains in the dark with Giyu to track Yae and the demon, timely saving Yae from an attack by Matazo.
Initially, Giyu wanted Shinobu to poison the demon directly, but they were stopped by the indecisive Yae. Ultimately, Giyu used Water Breathing, Fourth Form: Striking Tide to slay Matazo, ending the suffering of this father who had desperately resisted his demonic instincts to avoid attacking his daughter. Seeing this, Yae's will collapsed, and she resolved to shoot herself, but the gun's parts froze after being stained with her father's blood, and Shinobu eventually stopped her suicide. Afterward, Giyu conveyed Matazo's final request to his daughter before he vanished—to live on. Shinobu comforted Yae, saying that both she and Giyu had similar pasts and could understand Yae's sorrow, encouraging her to pull herself together.
Although Shinobu did not want Kanao Tsuyuri to join the Demon Slayer Corps, wishing for her to live as an ordinary girl (the mortality rate of the Demon Slayer Corps is high, and the three Tsuguko Shinobu previously had all died in battle during missions). However, Kanao learned Flower Breathing through observation and, of her own will, secretly participated in the Demon Slayer Corps' Final Selection without Shinobu's knowledge. After the selection ended, Shinobu took Kanao, who had become an official member, as her Tsuguko.
At the request ofOyakata-sama, Shinobu and Giyu headed to Natagumo Mountain to slay demons. FollowingZenitsu Agatsuma's sparrowChutaroshe found Zenitsu and the members who had been turned into spiders, saved Zenitsu and the others using medicine, and directed the Kakushi of the Demon Slayer Corps for follow-up processing. Later, while searching for demons in the mountains, she encountered the fleeing Spider Demon (Elder Sister). After seeing through her lies, she poisoned her using Butterfly Dance: Caprice and rescued the one trapped in the cocoon,Murata。
After Lower Rank Five,Ruiwas defeated, she intended to kill Nezuko Kamado, who was a demon, but was stopped by Giyu. Because Giyu Tomioka prevented her from killing the demon and even almost
During the trial, Shinobu empathized with Tanjiro after learning the reason why he traveled with a demon, showing care for the restrained Tanjiro. After the Hashira meeting ended, Shinobu took the initiative to suggest sending the Kamado siblings to the Butterfly Mansion. Once Tanjiro's group had recovered, Shinobu instructed her subordinates at the Butterfly Mansion to conduct rehabilitation training for them.
One night near the end of the training, Shinobu Kocho went to the roof to visit Tanjiro during his training. After Tanjiro saw through the anger hidden deep in her heart, she entrusted her unfulfilled dream of living in harmony with demons to Tanjiro,(This likely carries the meaning of a dying wish)。
Receiving a visit from Tanjiro, she learned about his past and his inquiryHinokami Kaguraregarding its origins, she suggested that Tanjiro seekthe Flame Hashirafor answers.
The anime added original scenes of the Hashira Meeting, Shinobu seeing them off,the Flame Hashiraand her recommending Tanjiro to the Master for the Mugen Train mission.
With her TsugukoKanao TsuyuriLearned from the Kasugai Crowthe Flame Hashiraafter hearing the news of the death in battle, her heart was very heavy.
Before her sister died, Shinobu learned from herthat the demon who defeated herliked to eat young women, so she planned to use herself as bait and consumed Wisteria poison for a yearBased on the timeline, she began ingesting the poison as early as the Mount Natagumo Arc。
Later, withTamayo'shelp, she further completed her body modification. During this period, Shinobu assisted Tamayo in developing a medicine to turn demons back into humans.When asked by Oyakata-sama to collaborate with a demon to create medicine, Shinobu's inner anger could not be quelled for a time, but after interacting with Tamayo, she came to respect her sincerely.
As the final battle approached, Shinobu informedKanaoof her plan: if she encountered Doma, she would use herself as bait. The 37kg of poison in her body would be enough to weaken Doma, and she told Kanao to take his head once the poison took effect. Besides the doses of the demon-to-human medicine used on Muzan and Nezuko, there were leftovers. To be safe, Shinobu also entrusted the remaining medicine to Kanao.
Shortly after falling into the Infinity Castle, she encountered Doma at the Lotus Pondwho was devouring a female member,Douma. She immediately realized that he was the culprit who killed her sister. At first, she tried to fight him head-on; although her speed amazed him, her lethality was limited and far from fatal. The various poisons she used were quickly decomposed by Douma, who then mocked her, saying, "If you were a bit bigger and cut my neck directly, you probably would have won!" At that moment, she felt immense hatred for her short stature and weak strength; if she were only taller and stronger, her blade could have reached the demon's neck to behead him. After a fierce struggle, she was severely injured. On the verge of death, the spirit of her sister Kanae appeared, giving her the resolve to die together with the enemy. After a failed suicidal attack aimed at his neck,sorrowfully,Just as plannedshe was devoured by Douma, becoming the first Hashira to fall in the Battle of the Infinity Castle. Before her death, she left a hand gesture for Kanao, who had arrived to support her, hinting not to inhale the Blood Demon Art within the ice crystals. Later, Kanao and the new reinforcement,Inosuke,successfully held out until the poison took effect. The toxin caused Douma's body to dissolve and crumble, and his Blood Demon Art was dispelled as a result. Douma struggled for a moment, but was still no match forthe powered-upKanao and Inosuke, and his head was sliced off. Her own hair ornament was inherited by Kanao.
After death, Shinobu Kocho's soul met Douma's soul again. After being confessed to by Douma, she mocked him with a smile, saying, "You should just go to Hell by yourself, you scum," and then her soul was reunited with her parents and Kanae's soul as she wished.
In the final battle, Tanjiro was turned into the Demon King by Muzan, and everyone was overwhelmed. Kanao remembered the medicine Shinobu had left behind and stabbed it into Tanjiro's body. As a result, Tanjiro successfully regained consciousness.
She appeared in the vision of Tanjiro, who had become the Demon King. In the ocean of the vision, she, along with other deceased people, used her hands to lift Tanjiro up, helping him break free from Muzan.
Many years after Muzan's death, the timeline shifts to modern-day Tokyo, where Shinobu and Kanaewas reincarnatedare high school students at the modern-day Sekirei Women's Academy, and on the road with the great-grandson of Kanao Tsuyuri.Kamado Kanatapassed by him and his classmate.
The Insect Breathing used is derived from Water Breathing (Water → Flower → Insect).
