Inosuke Hashibira

Inosuke Hashibira is one of the main protagonists of Demon Slayer: Kimetsu no Yaiba and along with Zenitsu Agatsuma, a traveling companion of Tanjiro Kamado and Nezuko Kamado. He is also a Demon Slayer in the Demon Slayer Corps.

Appearance
Inosuke is a young man of average height and pale complexion with an extremely toned and muscular build for his age, possessing large, defined muscles most notably over his stomach and arms. In sharp contrast to this, he has an incredibly pretty and feminine face, with large, wide eyes that are framed by an array of long eyelashes, their irises a dark to soft pale green, thin eyebrows, and what could be a small, well-mannered mouth. His thick, black hair reaches just past his shoulders, fading into blue at the tips and forming an unruly and uneven fringe that falls just above his eyes, puffing out before curving and thinning towards his forehead.

Inosuke wears his altered version of the standard Demon Slayer uniform, which consists only of the baggy hakama pants, his tinted a dark gray-blue, which he fastens around his hips with a thick belt of fluffy brown animal fur. The usual cloth leg-wraps are replaced with what appears to be knee-high socks of a furry hide which expose his heels and toes, which also appear to be what fastens the sandal-bases he wears on his feet. His most defining feature is the gray, hollowed-out boar's head he wears to mask his own.

Personality
Inosuke is an extremely short-tempered and proud young man who always likes to think he is the strongest fighter in a situation, constantly challenging most people he comes across and wanting others to respect and praise him for his skill. This often leads him into unnecessary danger, since he tends to overestimate his abilities in comparison to who it is he's fighting and refuses to accept when he's been defeated, which can be seen when Giyu Tomioka has to tie him up after his fight with the Father Spider Demon to prevent him challenging the Hashira to a fight while still severely injured from his previous battle. This constant wanting to be the best can also cause Inosuke to be very provocative, as he often tries to goad others, most prominently Tanjiro Kamado, into fighting him, although in the case of the latter he usually fails due to Tanjiro's obliviously kind nature.

Due to him having been raised by boars, Inosuke has also been shown to possess little understanding of normal human interaction, at least at the time of his debut, as he seems to frequently assume that people who approach him want to attack him and doesn't appear to understand the kindness others show him.

However, as the story goes on, Inosuke is influenced more and more by Tanjiro's ways and becomes more accustomed to affection and generosity, learning to also acknowledge the strength of people besides himself and develop feelings of friendship towards him and Zenitsu Agatsuma, although he does still retain his proud nature and constant want for praise. He also begins to think more strategically when engaging in combat, using smarter tactics he has picked up from more experienced Demon Slayers and not just rushing into fights head-on without thinking.

Physical Abilities
Enhanced Strength: Inosuke possesses above-average arm strength, by wielding two katanas as opposed to one, even swinging them at subsonic speeds.

Enhanced Flexibility: Inosuke is extremely flexible to the point where he can bend backwards so far that his head reaches between his feet.

Miscellaneous Abilities
Enhanced Senses: Like all skilled Demon Slayers, Inosuke possesses incredible sharp senses that allows him to detect things normal humans would be totally ignorant to.


 * 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.

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

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.

Fighting Style
Animalistic Combat: Due to growing up with boars in the mountains, Inosuke adopted their habits. This both his hand-to-hand combat style and swordsmanship very reminiscent of animals and beasts. Tanjiro Kamado noted that his unnatural fighting style which reassembles 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.

Swordsmanship
Beast Breathing: A Breathing Style distantly derived from Wind Breathing and the personal creation of Inosuke Hashibira himself after living in the mountains and fighting for survival.

The Beast Breathing combat style mimics beasts and wild animals, specifically their unpredictable and wild nature, including movements, attacks, and senses, and replicates it with the user's movements, techniques, and swordsmanship. Most, if not all, known techniques and forms are simple, straightforward yet wild, and unpredictable movements and attacks, although one of them utilizes the powerful sense of touch to replicate an animal's primal senses. When utilized properly, the user visualizes the claws and roars of wild beasts and animals emanating from their weapon, surroundings, or themselves."First Fang: Pierce - The user stabs the target's neck with both blades." "Second Fang: Rip and Tear - The user unleashes a double slash with his two blades in an X-shaped cut." "Third Fang: Devour - The user releases simultaneous horizontal slashes towards the target's throat." "Fourth Fang: Slice 'n' Dice - The user delivers multiple diagonal double slashes with both swords." "Fifth Fang: Crazy Cutting - The user slices everything in all directions." "Seventh Form: Spatial Awareness - The user utilizes their sense of touch to identify the position of enemies and their weaknesses by feeling small disturbances in the air. This technique was so strong that Inosuke Hashibira could sense all the demons spread out through a whole mountain."

Equipment
Dual Nichirin Katana: Like all Demon Slayers, Inosuke harbors a Nichirin Blade, but instead of one, he has 2, both of which he shaped a jagged edge like a beasts 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.
