Information about Inosuke Hashibira

Inosuke Hashibira is one of the main protagonists of Demon Slayer: Kimetsu no Yaiba and a traveling companion of Tanjiro Kamado and Nezuko Kamado, alongside Zenitsu Agatsuma. He is also part of the Demon Slayer Corps as a demon hunter.

Even if you have regrets, don’t cry! No matter how pathetic or humiliated you feel, you must go on living! That’s what Inosuke Hashibira says to Tanjiro Kamado and Zenitsu Agatsuma in the film Kimetsu no Yaiba: The Infinity Train.

Inosuke is a pale-skinned young man of average height, with an extremely toned and muscular constitution for his age. He has well-defined muscles, particularly in his stomach and arms. In contrast to this, he has an incredibly handsome, feminine face, with large, wide eyes surrounded by long lashes. His eyes range in color from dark to pale green. He has fine eyebrows and a small, well-defined mouth. His thick, black hair barely reaches his shoulders, with blue tips. He has an unruly, irregular fringe that falls just above his eyes, thickening before curling and thinning toward his forehead.

Inosuke wears his own modified version of the standard demon slayer uniform. He wears only a pair of loose hakama-style pants in a dark grayish blue, fastened at his hips with a thick, brown deer-fur belt. The usual leg protectors are replaced by bearskin socks that come up to his knees, leaving his heels and toes uncovered. This is also what holds the sandals he wears to his feet. His most distinctive feature is the hollow gray boar’s head he wears to conceal his own. He has modified the eyes on the head so that he can see through them when he wears it. It has been revealed that this head belonged to his adoptive boar mother, now deceased.

Inosuke is an extremely hot-tempered and proud young man. He likes to think of himself as the strongest fighter in any given situation, constantly challenging the people he meets and seeking their respect and praise for his skills. This often leads him to put himself unnecessarily at risk, as he tends to overestimate his abilities relative to his opponent and refuses to accept defeat. An example of this is when Giyu Tomioka has to tie him up after his fight against the Spider Demon Father, to prevent him from challenging the Hashira to a fight while still seriously injured from his previous battle. His constant drive to be the best can also make him very defiant, often seeking to provoke others, notably Tanjiro Kamado, to fight against him. However, he usually fails with Tanjiro due to the latter’s unconsciously kind nature.

Inosuke has a rather rancorous aspect to his personality, especially when he sees his loved ones hurt. He initially refused to help the wounded mechanic who had stabbed Tanjiro, convinced he was within his rights to let him die. He only agreed to help when Tanjiro begged and forgave the man. When he learned that Doma had killed and devoured Shinobu, Inosuke immediately attacked him. He became extremely furious when he discovered that Doma was also responsible for his own orphan situation. He single-handedly defied the Superior Moon, declaring that he was going to create hell for him. Inosuke even confronted Muzan directly, demanding that he redeem himself by dying for maiming and nearly killing all the other demon slayers.

Having been raised by wild boars, Inosuke showed a lack of understanding of normal human interaction, at least at the beginning of his story. He often seems to assume that people who approach him want to attack him, and fails to understand the kindness others show him. He can’t read or write, and has difficulty pronouncing people’s names correctly, saying “Monchiro” instead of “Tanjiro” or “Monitsu” instead of “Zenitsu”. He can be very rude, without intending to be, and treats everyone like an enemy to begin with.

However, as the story progresses, Inosuke is increasingly influenced by Tanjiro’s methods, and opens himself up to affection and generosity. He learns to recognize the strength of others and develops friendly feelings towards Tanjiro Kamado and Zenitsu Agatsuma. Despite this, he retains his proud nature and his constant desire to be praised. What’s more, he begins to think more strategically when he fights, using smarter tactics that he’s learned from more experienced demon slayers. He no longer rushes blindly into battle. Inosuke’s sense of camaraderie has improved considerably. For example, he threw himself at Muzan Kibutsuji, mourning the many demon slayers killed and maimed by the Demon King. He demanded that Muzan return everything he had taken from them or die in retaliation for his crimes.


General skills: Inosuke is an extremely skilled and talented swordsman. He managed to teach himself total concentration breathing and developed his own breathing style, known as “beast breathing”. He relied on his instincts and his upbringing among wild boars in the mountains, without any formal training. Inosuke is more than capable of hunting and killing demons on his own. He easily defeated the Horned Demon without any problems. On several occasions, he has demonstrated his ability to defend himself and contribute to battles against higher-ranking demons, such as Gyutaro and Daki, higher ranks 6, as well as Doma, a much more powerful higher rank 2. He also possesses inhuman senses, superhuman flexibility and a natural talent for combat. Most impressively, Inosuke managed to fend off the Demon King Muzan as well as his comrades, demonstrating fighting skills comparable to those of the Hashira, the most powerful swordsmen among demon slayers.

Animal imitation: Being raised with wild boars in the mountains, Inosuke adopted their behaviors and incorporated them into his fighting styles. Thus, his hand-to-hand combat style and his sword style are strongly reminiscent of the movements of animals and beasts. Tanjiro Kamado has noted that his unconventional fighting style resembles that of a “four-legged beast”, as his attacks come from an extremely low angle, are ferocious and use unique movements, making him unpredictable and formidable.

Increased flexibility: Inosuke possesses extraordinary flexibility, so much so that he can bend backwards to the point of having his head between his feet. He also demonstrates the ability to disarticulate his arm to extend his reach, and to disarticulate any joint on his body at will. This flexibility even extends to his internal organs, as evidenced by his ability to move his heart and prevent it from being pierced during his fight against Daki and Gyutaro.

Enhanced strength: As evidenced by his muscles and incredibly toned stature, Inosuke possesses superhuman physical strength. He is able to wield two katanas instead of one, even twirling them at impressive speed. He managed to slice through the parts of Enmu’s body that had engulfed one of the train’s cabins. During Hashira’s training arc, he was even able to move a boulder almost twice his size with his bare hands. He was able to inflict damage to Doma’s neck and hurl his swords with such force that the impact was enough to drive Kanao’s sword into his own neck.

Enhanced touch: Having grown up in the mountains, Inosuke has developed an extremely acute and sensitive sense of touch. His skin is able to detect the tiniest vibrations in the air. Inosuke has integrated this ability into his spatial awareness technique, using his sense of touch to spot demons scattered across an immense mountain and to pinpoint the position of the Spider Demon Father. Thanks to this ability, he is aware when he is being observed, particularly if the intentions are hostile. His sensitive skin also gives him an advantage against Doma, allowing him to naturally avoid inhaling his dangerous ice powder.

Extrasensory perception: Inosuke’s senses are so sharp that he possesses a form of extrasensory perception, enabling him to detect elements outside the usual field of perception. Inosuke can sense the intensity of his opponents, as when he perceived a drop in Daki’s sash attack, giving him an opening to counter-attack, or when he assessed the power of Akaza and Kyojuro Rengoku. He can also detect a person’s malice and intent to kill even when they’re out of his field of vision, which saved him from a lethal attack by Gyutaro’s scythe. Inosuke is also able to sense the presence of living people inside Daki’s obi, thus avoiding accidentally injuring them in battle.

Exceptional speed and reflexes: Inosuke is incredibly fast, as evidenced by his lightning dash through the Tsuzumi mansion and his ability to narrowly avoid the Horned Demon’s attacks, demonstrating his reflexes and speed of movement. A few months later, his speed and reflexes improved further, enabling him to fend off Daki’s obi sash while protecting the trapped humans, and then to confront the Superior Rank directly. With the help of Zenitsu and Tanjiro, Inosuke managed to get close to Daki and decapitate her before she could react. His superhuman speed is also demonstrated when he manages to stand up to Doma, the second-highest rank, sometimes managing to touch him and grab Kanao’s katana without Doma noticing, even though the sword is at his side. Even exhausted and wounded, Inosuke can rival Muzan in speed, then later the demon Tanjiro.

Exceptional stamina and endurance: thanks to his rigorous training as a demon slayer, Inosuke has developed remarkable stamina and endurance, which he has demonstrated time and again. Both he and Zenitsu were able to face Daki awake for an extended period of time, despite their injuries, and managed to cut off his head. What’s more, Inosuke played a crucial role in the High Rank’s defeat, even after being stabbed in the chest and fatally poisoned. Later, he proved impressively resilient against the second most powerful High Rank demon, withstanding countless attacks. In his fight against Muzan, he suffered multiple injuries, both minor and serious, but persevered to defeat the Demon King and, later, to fend off the demon Tanjiro.

Unshakable willpower: Inosuke possesses an incredibly strong will and spirit, never wavering and remaining courageous in the face of any enemy, even to the point of putting himself in danger. His willpower was demonstrated in his fight against Doma, the second-highest rank, where despite his many wounds, he refused to give up and continued to fight against the demon, despite its overwhelming power. Even in the face of the Demon King, Inosuke remained steadfast and never gave up.

Poison resistance: Inosuke was able to resist and survive to some extent the effects of the higher rank 6 poison, although it is considered incredibly deadly. This suggests that he may have some immunity to certain toxic substances. However, as Aoi Kanzaki pointed out, it also means that Shinobu Kocho’s antidotes won’t work on him. So, if he’s exposed to a poison more powerful than Gyutaro’s, or one to which he hasn’t developed resistance, these antidotes won’t be able to be used to heal him, increasing the danger of death.

Repetitive action: this technique, practiced by a few members of the Corps, enables a person to achieve effects similar to breathing through total concentration by repeating predefined movements or recalling intense feelings. This opens up the five senses and enhances concentration, using the body’s physical capacities over a long period of time. It is possible to use repetitive action and breathing simultaneously through total concentration, giving the user immense strength capable of rivaling higher-ranking demons. Inosuke quickly mastered this technique after observing it at Tanjiro’s and enjoys repeating “Boar Rush!” as he performs it.

Battle style

Sword mastery: Inosuke has demonstrated exemplary skill in handling his Nichirin katanas, enabling him to face and defeat demons on several occasions, and even to take on members of the Twelve Kizuki. As he approaches the Infinity Castle Bow, Inosuke has undeniably perfected his swordsmanship to a level comparable to that of a Hashira, enabling him to follow and challenge Doma, one rank above two.

Sword mastery

Beast Breathing: Beast Breathing is a breathing style developed by Inosuke Hashibira himself, drawing inspiration from his life in the mountains and his struggles to survive. The style also seems to be influenced by the wild boars he grew up with, but is also loosely derived from wind breathing.

Double Nichirin katana: Unlike most demon hunters, Inosuke wields two Nichirin katanas. These swords are chipped and have numerous notches on the blade edge, enabling them to tear and rip demon flesh rather than slice cleanly, a method Inosuke prefers. Both blades are a deep indigo. Unlike his fellow demon hunters, Inosuke uses neither handles nor scabbards for his swords, preferring instead to wrap them in bandages to improve his grip. What’s more, the blades bear no engraved inscriptions.

  • Like Tanjiro, Inosuke is deaf.
  • Inosuke has a strong platonic relationship with Nezuko.

Give them everything! Give them back! If you can’t do that… Then you’ll pay with a million deaths!”
