Inosuke Hashibira

Inosuke Hashibira (嘴平伊之助 Hashibira Inosuke?) is a Demon Slayer in the Demon Slaying Corps and traveling companion of Tanjiro Kamado. 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 appear to be knee-high socks of 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 as to mask his own, the eyes of which he has tampered with to allow himself vision while wearing it, which has been revealed to have belonged to his late adoptive boar mother. 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 literally has to tie him up after his fight with the Father Spider Demon to prevent him challenging the Pillar 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 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. The "ino" in his first name sounds similar to the Japanese word for "boar" (猪 inoshishi?)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. Inosuke is extremely flexible, to the point where he is able to bend over backwards so far that his head reaches between his feet, and dislocate any of the joints in his body at will. Inosuke was able to resist and survive the effect of Upper Moon Six'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.
