Inosuke Hashibira

Inosuke was extremely temperamental, impulsive, not very patient, and full of excessive pride. His pride was such that he was even willing to fight against opponents who were technically stronger than him [11]. He was not the kind of person who stopped to think about the difference in levels that existed between him and his opponent, which often put him in serious danger of dying. This has happened on several occasions, such as when he was convinced of being able to defeat the Higher Moons Six, Daki and Gyutaro, after being influenced by the words of Tengen Uzui [12].

At times he had trouble admitting defeats to him, so he was a bad loser and was always trying to compete against Tanjiro Kamado and provoke him into fighting him, failing miserably in his attempts [13]. Despite this, deep down Inosuke seemed to have an insecurity that he hid with his arrogant attitude for not knowing how to adapt to those around him and with the fear of being rejected for being different. His low self-esteem becomes known after his defeat suffered by one of the Spider Demons and then humiliated by the water pillar Giyu Tomioka, even apologizing to his companions for his weakness.

Because he grew up alone in the mountains, Inosuke had trouble interacting with others and only cared about himself most of the time. However, as time goes on, he becomes more influenced by the kindness and good deeds of the people around him, and he also begins to think and use strategies before facing an opponent. Every time he interacted with other people he didn't know, the first thing he did was assume that he was an enemy and that he thought about attacking him, ready to fight him. This may be due to having grown up surrounded by wild animals which, as an instinctive reaction to danger or towards something unknown, they put themselves on guard, ready to defend themselves against any possible threat.

Inosuke was a young man of average height[3]. He always wore a mask made of a boar's head[4] with grey fur and blue eyes[5]. Instead of wearing the standard Demon Slayer uniform, he wore a black Hakama with a skirt made of fur at the waist protecting his groin and genitals[6]. By not wearing the jacket of the average Demon Slayer uniform, he showed off his torso which had a completely muscular and toned appearance[7].

When not wearing his Boar mask, Inosuke's face was that of an effeminate-looking young man[8] with short dark hair with extensions that faded into shades of blue and green eyes[9] with thick eyelashes accentuating his feminine-featured face[10].

Personal skills
High Sensitivity of Touch: As a result of living in the mountains for most of his life, Inosuke had developed a rather acute sense of touch. Thanks to this highly developed sense, he was able to sense even the slightest vibration in the air, thus managing to detect both enemies and allies.
Flexibility: Inosuke had complete control of his own body, even being able to dislocate the joints of his limbs to execute more effective attacks at greater distances. He was also able to move in tight spaces.
Ability to move organs at will: This ability allowed him to move his vital organs around his body, preventing them from being damaged by any external physical attack.
Skills as a Swordsman
Main article: Beast's Breath
As a member of the Demon Slayer Corps, Inosuke was a very powerful and talented swordsman. His combat style consisted of Beast Breath (獣ケダモノの呼こ吸きゅう,, Kedamono no Kokyū?). Throughout his active time as a hunter, he faced numerous powerful enemies and members of the Twelve Demon Moons.

Master Swordsman: He possessed a high level in the use of Nichirin swords, being one of the powerful swordsmen of his generation. He was even capable of using two swords in combat; these were splintered at the edge of the blade allowing him to tear the flesh of his opponents with great ease. His skills as a swordsman allowed him to face and defeat Upper Moon Two, Doma with the help of Kanao Tsuyuri. He was also able to cut off the head of the former Upper Moon Six, Daki.
