Abilities

Overall Abilities: Despite being only two ranks from the bottom, Inosuke is a Hashira-level swordsman with incredible abilities and attributes. He has shown to be able to hold his own and contribute in fights against Upper Rank demons and being more than capable of disposing demons by himself. He is also incredibly gifted, possessing inhuman senses and flexibility, as well as the skills necessary to make his own breathing style and use it to great effect.

Animalistic Combat: Due to growing up with boars in the mountains, Inosuke adopted their habits. Both his hand-to-hand combat style and swordsmanship are very reminiscent of animals and beasts. Tanjiro Kamado noted that his unnatural fighting style which resembles that of a "four legged beast" due to how his attacks come from an extremely low angle while also being very ferocious and incorporating other unorthodox movements, thus making him very unpredictable and very vicious.

Animal Imitation: Due to living and growing up with wild boars, Inosuke has learnt to imitate many of their behaviors, which contributed to his proficiency in his Beast Breathing.

Enhanced Flexibility: Inosuke is extremely flexible to the point where he can bend backwards so far that his head reaches between his feet.^[8] He later displays the ability to dislocate his arm to extend his reach^[9] and dislocate any of the joints in his body at will.^[10] This flexibility additionally extends to his internal organs, as he was able to shift his heart and avoid it being pierced in the fight against Daki and Gyutaro.^[11]

Enhanced Touch: After growing up in the mountains, Inosuke developed a sharp and incredibly sensitive sense of touch. He can even feel small vibrations in the air. By using this ability, he can tell if anyone is looking at him, especially if they have any hostile intentions. He can even pinpoint the exact location they are looking at, which gives him an edge in combat.^[12]

Extrasensory Perception: Inosuke's senses are honed to such extremes that he possesses a form of extrasensory perception that allows him to detect things humans are completely ignorant to. Inosuke can sense how serious his opponent's are, seen when we sensed that Daki's sash attacks were relaxing a little bit, which gave him an opening to attack^[13] and how strong Akaza and Kyojuro Rengoku were. He was also able to sense a person's malice and intent to kill even when they are outside his range of sight, which prevented him from getting killed by Gyutaro's scythe attack. Inosuke was also able to sense that Daki's obi had living people trapped inside it, which prevented him from accidentally harming them when fighting.

Immense Speed & Reflexes: Inosuke is an incredibly fast individual, being able to keep up with the movements of Doma and later on, a weakened Muzan Kibutsuji.

Immense Stamina & Endurance: During the Sunrise Countdown Arc, he lasted around half an hour exerting himself to the peak of his physical and mental condition, despite sustaining wounds all over his body.

Immense Strength: Inosuke possesses amazing arm strength, being able to dual wield two katanas as opposed to one, even swinging them at super speeds. He was able to slice up the parts of Enmu's body that had engulfed one of the train cabins. During the Hashira Training Arc, he even managed to move a boulder nearly twice his size with his bare hands. He was able to damage Doma's neck and throw his swords with such strength, the force on impact was enough to help Kanao kill Doma. He is also able to use precision in his strikes, as he was able to cut Daki's obi easily, while not harming the people trapped inside.

Indomitable Will: Inosuke possesses an incredible and undaunted will and spirit, never faltering and remaining steadfast and courageous in the face of any foe, to the point where it endangers himself. His will was best displayed during his battle against Upper Rank 2, Doma, where despite sustaining dozens of injuries, he refused to give up and continued to fight the Demon despite his overwhelming power.

Poison Resistance: Inosuke was able to resist and survive the effect of Upper Rank 6's poison although it was considered incredibly deadly, which suggests that he may have complete immunity to some poisonous substances. However, as stated by Aoi Kanzaki, this also means that none of Shinobu Kocho's medicines will work on him, so if he is exposed to a stronger poison than that of Gyutaro or one that he has not developed a resistance to, they cannot be used as a remedy and he is in greater danger of death.^[14]

Repetitive Action: A technique practiced by few members in the Corps, it allow a person to achieve the same effects as Total Concentration Breathing by using repeating pre-set movements or remembering intense feelings to open the five senses and raise their concentration, drawing out the physical powers of the body for an long extended period. It is possible to use both Repetitive Action and Breathing simultaneously, granting the user immense strength able to rival Upper Demon Moons. Inosuke quickly mastered this technique after watching Tanjiro and likes to rephrase "Pig Assault" while doing so.

Fighting Style

Master Swordsman: Nearing the Infinity Castle Arc, Inosuke has polished his swordsmanship to the level of a Hashira, allowing him to keep up with Upper Rank 2, Doma.

Swordsmanship

Equipment

Dual Nichirin Katana: Like all Demon Slayers, Inosuke harbors a Nichirin Blade, but instead of one, he has two, both of which he shaped a jagged edge like a beast's teeth and jaws, perfect for tearing through flesh, which is more to his liking. He doesn't have a hilt or scabbard, but rather uses bandages to tie his katanas, unlike his fellow Demon Slayers. His dual blades are indigo-gray in color.
