Demon Slayer's Inosuke Hashibira may be well intentioned, but his hot-headed disposition and impulsive attitude make him a serious liability. Despite his best efforts to improve a situation for himself, his fellow Demon Corps members, or the general public, Inosuke often makes a bad situation significantly worse.
His sword prowess notwithstanding, Inosuke's heedlessness puts himself and others around him at risk. When he's not infuriating people with imprudent speech, he's recklessly jumping into action without considering the consequences. Inevitably, Inosuke's severe lack of composure and injudicious way of thinking threatens not only the Demon Corps' mission but the lives of his peers.
10 Inosuke Recklessly Attacks Kyogai And Tanjiro
After defeating Sasumaru and Yahaba, Tanjiro, carrying Nezuko on his back, makes his way south-east at the behest of a Kasugai crow. On the way, he meets Final Selection survivor Zenitsu. They head into the mountains where they discover a pair of scared children outside a demon's house. Hopeful they can save the children's brother, Tanjiro and company enter the house where Tanjiro discovers the demon, Kyogai. As Tanjiro and Kyogai square off, Inosuke enters the fray and recklessly attacks the demon. After Kyogai forces the room to spin, Inosuke steps on Teruko. Infuriated, Tanjiro tosses Inosuke off of the child, but this just makes the reckless Demon Slayer rasher as he attacks Tanjiro, making an already dire situation worse.
9 Inosuke Savagely Beats Zenitsu
During the battle between Tanjiro and Kyogai, Zenitsu and Shoichi are thrown outside when Kyogai forces the entire house to shift using his Blood Demon Art. Unfortunately, the two run into Inosuke. After learning that there is a demon in Tanjiro's box, Inosuke makes a beeline for it, ready to kill the demon inside.
Zenitsu, knowing how much the box means to Tanjiro, steps in front of it to stop him. Inosuke then savagely beats Zenitsu and prepares to stab him before Tanjiro forces him to stop after striking him in the ribs. When Inosuke eventually regains his composure, he attacks Tanjiro, and once again causes more trouble for his fellow Demon Slayer.
8 Inosuke Acts Rashly On Mount Natagumo
On Mount Natagumo, Tanjiro and Inosuke meet Murata, a member of the Demon Slayer Corps. Murata complains that they should have sent a Hashira instead of Mizunoto-ranked Demon Slayers. Frustrated by Murata's comments, Inosuke audaciously punches him in the face and berates him while completely disregarding his seniority. Later, when Murata's comrades begin to attack the group, Inosuke rashly declares he will slash them all. Tanjiro tells Inosuke he can't, which results in Inosuke unnecessarily head-butting him in the stomach. Even while embroiled in battle, Inosuke still recklessly puts his fellow Demon Slayers at risk.
7 Inosuke's Inflated Ego
When the Father Spider Demon attacks Tanjiro and Inosuke on Mount Natagumo, Tanjiro quickly tries to come up with a way to defeat him after discovering how difficult it is to slash the demon. Inosuke, on the other hand, attacks the demon with reckless abandon. As the battle wages on, the two Demon Slayers are separated, leaving Inosuke alone to fend for himself. Inosuke manages to hack off the demon's arm and it flees to a nearby tree. When Inosuke rediscovers the demon, he laughs and arrogantly assumes the demon is afraid of him. This allows the demon time to recover and gain the upper hand in their battle.
6 Inosuke Challenges Giyu
Giyu arrives on Mount Natagumo and saves Inosuke by quickly defeating the Father Spider Demon. Surprised by Giyu's unbelievable strength and ability, Inosuke's hubris leads to him challenging the Hashira to a fight.
Unfazed by the lack of success he had against the Father Spider Demon, Inosuke claims that he will defeat Giyu and become stronger than him, since Giyu just killed one of the Twelve Kizuki. Unimpressed with Inosuke's lack of knowledge, Giyu clarifies that the demon he defeated was not from the Twelve Kizuki. Shortly after, despite Inosuke's bold claims, Giyu decides he is too proud to realize how hurt he is from battle and ties him to a tree.
5 Inosuke Causes A Stir
Following the battle on Mount Natagumo, the group's next assignment is to slay the demon responsible for the disappearance of 40 Demon Slayers on the Infinity Train. When they arrive at their destination, Inosuke, having never seen a train before, gets ready to unsheathe his swords and do battle with it. Despite not knowing what it is himself, Tanjiro tries to deescalate the situation and tells Inosuke not to attack. Zenitsu explains that it is just a train, but Inosuke refuses to listen and throws himself headfirst into the carriage. This causes a scene and forces the three Demon Slayers to flee to avoid being caught by the police for having swords in their possession.
4 Inosuke Refuses To Think Before He Acts
While aboard the Mugen Train, the group, now joined by the Hashira, Kyujuro Rengoku,come across a demon in one of the carriages. Rengoku, the wisest among the four, remains calm and warns the demon. Inosuke arrives moments after Rengoku and, instead of thinking about how to prevent any casualties on the train, completely disregards Tanjiro's call to help the passenger first and immediately leaps into action. Inosuke's arrogance once again makes things unnecessarily difficult for the Demon Slayers as Rengoku is forced to save him from an attack before getting the passenger out of harm's way.
3 Inosuke Is Terribly Inconsiderate
When the trio, along with the Hashira Uzui, arrive at their destination in the Yoshiwara Entertainment District, Uzui explains the mission. He informs the trio that they are there to help him find his three wives and gather information on the demon causing trouble in the district. While Zenitsu becomes infuriated with Uzui for having three wives, Inosuke casually and insensitively blurts out that it is likely Uzui's three wives are already dead. Tanjiro gasps at Inosuke's lack of discretion before an annoyed Uzui punches him in the stomach.
2 Inosuke Ruins The Ogimoto House
While in the Ogimoto House, Inosuke overhears some of the attendants discussing Makio being unwell and not wanting to leave her room. Sensing something is wrong, Inosuke investigates and goes looking for Makio. He finds her room, but discovers that it is empty.
Noticing that the room is disheveled, Inosuke realizes the demon is nearby. When the demon moves above him in the ceiling, Inosuke follows it, hurling himself through multiple walls in the process and surprising the other workers. Thinking he has discovered where the demon is, Inosuke mistakenly strikes an unsuspecting client, leaving the Ogimoto House in disarray.
1 Inosuke Doesn't Consider The Consequences Of His Actions
As the Demon Slayers go on the hunt for the demon responsible for Uzui's missing wives, Inosuke frightens the girls at Ogimoto House when he dons his boar mask and further damages the building by bursting through the ceilings and floorboards with no regard for anyone around him. Panicked, the house girls flee and watch as Inosuke uses his swords to create another hole in the floor where he believes the demon is. Unable to fit in the hole, Inosuke dislocates his bones to the sheer horror of the house girls as they look on in disbelief when Inosuke burrows underground.
