Inosuke Hashibira

Subsequently, Enmu ordered several human subordinates to infiltrate the group's dreams using ropes, intending to enter their unconscious realms to destroy their "spiritual cores," rendering them useless before killing them. However, Zenitsu, due to his overly strong self-awareness, appeared in his own unconscious realm and attacked the intruders, as did Inosuke Hashibira. Then, Enmu neutralized Nezuko's Blood Demon Art, and with Tanjiro's call, Zenitsu, still asleep, joined the battle and rescued Nezuko from Enmu, who had merged with the train.

Zenitsu then followed Kyojuro Rengoku's instructions and, along with Nezuko, protected the passengers. When Zenitsu arrived outside the train at dawn, he discovered that Kyojuro Rengoku had suffered fatal injuries and ultimately succumbed to his wounds. Later, Zenitsu learned from Tanjiro of the arrival of Upper Moon Three, Akaza, and was deeply shocked. Afterwards, Zenitsu wept bitterly over Kyojuro Rengoku's sacrifice. From that moment on, Zenitsu never again deserted or caused trouble during missions.

During the battle in the Entertainment District, when the Sound Tengen Uzui, came to the Butterfly Mansion to capture people, Zenitsu volunteered to go to Yoshiwara Tengen Tanjiro Inosuke Hashibira, replacing Aoi Kanzaki.

Later, Tengen disguised her as a courtesan named "Zenko" and infiltrated the famous brothel "Kyogokuya" in Yoshiwara. Her colleagues described her as "ugly but musically talented." Because she was forced into Kyogokuya- ya after being belittled by Tengen, Zenitsu resolved to become the top courtesan in Yoshiwara and teach Tengen a lesson.

Seemingly unlikely, Zenitsu, hearing a girl crying, went to investigate and found Warabihime, the star Warabihime of Kyogokuya, assaulting another girl. During their argument, Zenitsu heard a demon's voice in hers, confirming she was a demon. Despite his fear, Zenitsu mustered his courage and protected the injured girl from Warabihime's attack, but was immediately knocked unconscious by Warabihime —Upper Moon Daki— who discovered his identity as Demon Slayer Corps. Subsequently, Zenitsu and Maki, Tengen's wife who had been kidnapped, were swallowed Makio Daki's ribbon clone and imprisoned underground as food.

Afterwards, Zenitsu was rescued by Inosuke Hashibira after he went underground and caused a ruckus, and joined the battle while asleep. Then, after Tengen arrived and instantly killed Daki's clone, Zenitsu rushed to support Tanjiro with Tengen and Inosuke Hashibira, but because Tengen was too fast, he and Inosuke Hashibira arrived a step too late and discovered that another Upper Moon Six, Gyutaro, had already appeared.

Later, during the battle with Gyutaro and Daki, Zenitsu demanded that Daki apologize to the girl she had abused. However, the Zenitsu corrupt Daki immediately refused and unleashed all her power. Zenitsu, Tanjiro, and Inosuke Hashibira then ganged up on Daki, and Inosuke Hashibira eventually beheaded her. However, since the two demons were two separate entities, they would not die unless both were beheaded simultaneously. Inosuke Hashibira was thus stabbed in the chest by Gyutaro's poisoned scythe and collapsed from the poison. Tengen, who had been fighting Gyutaro for a long time, also collapsed due to the spread of the poison within him. Zenitsu himself and Tanjiro were ambushed by Daki and fell unconscious.

After fainting, Zenitsu once again entered a semi- Awakening state. While Tanjiro was retaliating against Gyutaro, Zenitsu and Inosuke Hashibira also began to attack Daki together. In the end, as Tanjiro Awakening his Demon Slayer Demon Slayer Mark and beheaded Gyutaro, Daki was also beheaded by Inosuke Hashibira Zenitsu together.

After the battle, Zenitsu woke up to find himself covered in injuries, but had no recollection of what had happened.

After Tanjiro and the others returned from the Swordsmith Village, Zenitsu to discover that Nezuko had overcome the effects of sunlight. He then proposed to Nezuko, who was now able to speak. However, Nezuko could only call Inosuke Hashibira by his name, which greatly annoyed him.

So cute! You're back, Inosuke Hashibira... I'm going to slaughter that pig!

While undergoing hellish training under the Wind Pillar Sanemi Shinazugawa attempted to escape due to the grueling training, but was Sanemi Shinazugawa. Later, when Sanemi Shinazugawa intended to cripple Genya Shinazugawa and expel him from the Demon Slayer Corps, Genya Shinazugawa was rescued at Tanjiro's request. However, Zenitsu angered Genya Shinazugawa by speaking ill of Sanemi Shinazugawa and was beaten up. In the end, Sanemi Shinazugawa and Tanjiro fought until dusk, and were ultimately forbidden from contact by their superiors.

Afterwards, Zenitsu and Tanjiro went to the residence of the Stone Pillar, Gyomei Himejima training, but soon after arriving, Zenitsu fainted from the shock of the training. During the training, Zenitsu received a message from Chuntaro sparrow, learning the devastating news that his "grandfather" had committed seppuku because his senior brother Kaigaku, had become a demon. Overwhelmed with grief and after much internal struggle, Zenitsu finally realized that he had to settle things with Kaigaku.

In the Infinity Castle, Zenitsu actively seeks out his former Demon Slayer Corps senior, Kaigaku, the new Upper Moon Six, who had fallen to the demonic path, and engages in battle with him.

When Zenitsu questions why he became a demon, Kaigaku claims he will only follow those who can accurately assess him. In his view, praise is justice, and the opposite is evil. Because his master always wanted him and Zenitsu, whom he despised, to inherit the Thunder Breathing, Kaigaku, who believes himself far superior to Zenitsu, then declares he has no intention of taking responsibility for his master's death, stating that in his eyes, his master Zenitsu are the same. Later, an enraged Zenitsu retorts, mocking Kaigaku: if he is a "useless" person who can only use the First Form, then Kaigaku is a "trash" person who can't even learn the First Form.

Zenitsu's words successfully enraged Kaigaku, and the two officially began their battle. During the fight, Zenitsu repeatedly recalled their past together, and with a heavy heart, he finally made the solemn decision to part ways with Kaigaku. Then, after enduring Kaigaku's second through sixth forms of Thunder Breathing sword techniques, Zenitsu, thinking, "I'm sorry, brother," used his seventh form, Honoikazuchi no Kami, which he had created in the air in the hope of fighting alongside Kaigaku, to behead him in a single strike. He closed his eyes in sorrow and despair.

With a single strike, the Honoikazuchi no Kami and Thunder God decapitated Kaigaku. Zenitsu, who had fallen unconscious in mid-air, was saved by Yushiro before landing. Kaigaku, now decapitated, died alone after being mocked by Yushiro said, "You don't know that giving will never bring receiving, and if you let your desires swell, you will eventually have nothing and die alone. How tragic."

You are my pride...

While in a coma, Zenitsu, in the liminal space between life and death, saw his "grandfather" on the other side of the river. Believing it was all his fault that Kaigaku had become a demon, Zenitsu apologized to his master, feeling he hadn't properly repaid him. However, just as Zenitsu was about to cross the Sanzu River after his apology, his "grandfather," Jigoro, tearfully said to him, "Zenitsu... you are my pride."

Immediately afterward, Zenitsu was pulled back from the brink of death by the members of "Kakuna" and regained consciousness. Subsequently, Zenitsu and Murata acted together and successfully reunited with Inosuke Hashibira and Kanao Tsuyuri, who had already defeated Upper Moon Two, Doma.

When Yushiro manipulated Nakime to control the movement of the Infinity Castle in order to deal with Muzan Kibutsuji, Zenitsu and the others felt the Infinity Castle vibrate.

Not long after, due to Nakime's death, the Infinity Castle began to completely collapse. However, Yushiro still managed to use Nakime's remaining active cells to make the Infinity Castle break through the ground. At the moment the Infinity Castle broke through the ground, Zenitsu and the others were able to escape from the Infinity Castle, which then completely collapsed.

The final battle finally took place on the ground... Zenitsu fell due to Muzan's attack, but was later confirmed to be alive. He then joined the other members in attacking Muzan. After the final battle, he lived with Tanjiro, Nezuko, and Inosuke Hashibira for a period of time, and later married Nezuko.

A new era dawned, and time flew by, bringing them to modern-day Tokyo. There appeared their great-grandchildren, Toko Agatsuma Zensho Agatsuma, siblings. Zentō happened to be in his family's storeroom reading Zenitsu's autobiography about slaying demons.

Remembered by his great-grandchildren living in modern Tokyo

Proficient in Two Sword Style. Growing up in the mountains, Inosuke Hashibira possesses an unusual "touch," allowing him to sense the movement of air. His swordsmanship style is his own creation Beast Breathing. A prodigy who, without a trainer, stole a sword from Demon Slayer Corps member and passed the Final Selection to join the team.

Appearance and Clothing: A burly young man wearing a gray boar head mask, deer fur around his waist, bear fur around his feet, and shirtless, only wearing Demon Slayer Corps trousers on his lower body. The true face beneath the mask is that of a beautiful girl, so beautiful that even the arrogant Upper Moon Six, Daki, has to admit his good looks.

He used to live alone in the mountains, and his hobby was to compete with wild animals in strength. Because of his lack of common sense, he was troubled and had difficulty understanding human warmth, but as he spent time with his companions, Inosuke Hashibira gradually came to understand human emotions.

His catchphrase is "rushing forward like a pig," and although he has a competitive spirit, he's surprisingly sensitive. While he often mispronounces people's names, he actually remembers them all.

When Inosuke Hashibira was young, his mother Kotoha Hashibira, couldn't bear the domestic violence from her husband and mother-in-law, so she ran away from home with the then-infant Inosuke Hashibira. However, the two of them were unexpectedly taken in by Upper Moon Two, Doma, Doma demon, and became followers of the Eternal Paradise Faith.

Because of Kotoha Hashibira's sweet singing voice and adorable personality, Doma originally had no intention of eating Kotoha Hashibira and her child, and even considered letting them stay with him until they died of old age. However, one day, Doma caught Kotoha Hashibira eating people. Although Doma tried to explain, Doma, Kotoha Hashibira had seen through his true nature, did not believe Doma. In order to save Inosuke Hashibira's life, Kotoha Hashibira chose to escape, but ended up getting lost and ending up at the edge of a cliff. In the end, Kotoha Hashibira had no choice but to throw the infant Inosuke Hashibira off the cliff and let him drift away down the river, but she was killed by Doma who caught up with her.

Later, Inosuke Hashibira was fortunate enough to be raised by a female wild boar, which allowed him to survive.

In the years following his childhood, while living on the mountain, Inosuke Hashibira would often visit the home of a young man named Koji at the foot of the mountain. He would ask Koji's grandfather, who suffered from Alzheimer's disease, for food. During this time, Koji's grandfather would often teach Inosuke Hashibira to read the "Hyakunin Isshu" (Hyakunin Isshu). Surprisingly, Inosuke Hashibira had been raised by wild boars since childhood, not only did not fail to understand it, but also quickly learned human language.

After some time, Koji began to worry that his grandfather and Inosuke Hashibira would be in danger if they spent too much time together, so he tried to drive Inosuke Hashibira away several times, but in the end, the young Inosuke Hashibira took over his house instead.

In the selection arc, when Inosuke was 15, a Demon Slayer Corps member accidentally wandered into the mountain where Inosuke Hashibira lived. Inosuke Hashibira then forcibly "competed in strength" with him. Afterwards, Inosuke Hashibira forcibly stole his opponent's Nichirin Sword and learned from him about the Demon Slayer Corps, the existence of demons, and the Final Selection of the Demon Slayer Corps.

Afterwards, without any guidance from others, Inosuke Hashibira created his own "Beast Breathing" technique and single-handedly entered the Final Selection of Mount Fujikasane. Ultimately, Inosuke Hashibira successfully became one of only five students— Tanjiro Kamado, Zenitsu Agatsuma Kanao Tsuyuri, and Genya Shinazugawa —to pass the Final Selection and qualify. However, after passing the test, Inosuke Hashibira ran off the mountain without even taking his Kasugai Crow, so Tanjiro was unaware that he was also among the successful candidates. The Kasugai Crow issued to Inosuke Hashibira by the Demon Slayer Corps nearly ate him more than 18 times, causing it to often hide and avoid showing itself.

In the Drum Mansion arc, after receiving the mission, Inosuke Hashibira entered the Drum Mansion alone to carry out a demon-slaying mission. However, because he was not good at navigating buildings, and because the structure of the mansion was constantly being altered by Kyogai's Blood Demon Art, the head of the Drum Mansion, Inosuke Hashibira wandered aimlessly around the mansion for three whole days without managing to kill his target—the former Lower Moon Six, Kyogai. Just as Inosuke Hashibira was pondering how to find his target, Zenitsu, who had barged into the mansion, unexpectedly bumped into him.

Like fighting a wild beast Inosuke Hashibira sensed a target nearby through the corridor and excitedly rushed out of his room, Luffy the corridor straight into the Kyogai and Tanjiro were. However, lacking social skills Inosuke Hashibira recklessly stepped on the young Teruko upon entering the room. When attempts to stop him failed, an enraged Tanjiro threw Inosuke Hashibira away. Inosuke Hashibira, now intrigued by Tanjiro, disregarded even Kyogai beside him and began attacking Tanjiro. However, Kyogai's Blood Demon Art disrupted the room's layout, and Inosuke Hashibira was teleported away.

After Kyogai was killed by Tanjiro, Inosuke Hashibira sensed through his touch that all the demons in the mansion had been eliminated, so he immediately returned outside. He then detected the demonic aura emanating from Tanjiro Nezuko Kamado had placed outside the Demon House, and intended to kill Nezuko inside. However, Zenitsu fiercely protected the box, preventing Inosuke Hashibira touching it. It turned out that Zenitsu had previously heard Tanjiro say that the box containing Nezuko was very important to him, so even knowing it contained a demon, he was determined to protect it at all costs. Because of this, Inosuke Hashibira repeatedly assaulted Zenitsu, trying to move him away from the box.

Shortly after, Tanjiro and Teruko returned outside after rescuing Kiyoshi and found Zenitsu being beaten. To protect his sister Zenitsu, Tanjiro immediately tried to stop Inosuke Hashibira, but Inosuke Hashibira, naive and inexperienced, only wanted to fight Tanjiro. During the battle, Inosuke Hashibira's attacks were unusually low, described by Tanjiro as "fighting like a four-legged beast." Inosuke Hashibira also disregarded his own injuries. To calm him down, Tanjiro used Headbutt to punish him. Inosuke Hashibira's hood fell off, revealing a beautiful, girlish face beneath the mask. However, Inosuke Hashibira suffered a concussion from Tanjiro's Headbutt and fell unconscious.

After waking up, Inosuke Hashibira could remember but couldn't pronounce the words correctly, immediately started chasing Zenitsu again, shouting and yelling, determined to prove himself. When burying the dead in the Drum Mansion, Inosuke Hashibira refused to help because he didn't understand the meaning of it, but Tanjiro mistakenly thought that Inosuke Hashibira because he was injured, so he told him to rest. Feeling looked down upon, Inosuke Hashibira angrily buried all the dead in a fit of rage.

On their way down the mountain, Tanjiro learns that Inosuke Hashibira is an orphan who grew up in the mountains. Determined to make Inosuke Hashibira less lonely, Tanjiro resolves to befriend him. However, Inosuke Hashibira keeps mispronouncing Tanjiro's name, leading to another argument. Upon arriving at the Wisteria House, Inosuke Hashibira, still recovering from his earlier Headbutt defeat at Tanjiro 'Tanjiro hands, deliberately provokes him. However, Tanjiro is completely oblivious to this, Inosuke Hashibira's provocations are ineffective. During his recovery, the head of the Wisteria House, Granny Hichiru, keeps unexpectedly appearing near Inosuke Hashibira. Because Inosuke Hashibira can easily sense others approaching by touch, he perceives her as a terrifying person.

After receiving the mission, Inosuke Hashibira left the Wisteria House with Tanjiro Zenitsu. Before leaving, Inosuke, who had grown up in the mountains and therefore lacked common sense, was very troubled by Inosuke Hashibira's kindness and could not understand the meaning of the exorcising Hanabi Hyuga that Mrs. Hatsumi offered to everyone.

Upon arriving at their destination, Zenitsu hesitated to proceed due to his fear of the demons in the mountains, so Inosuke Hashibira went ahead with Tanjiro into Mount Natagumo. During this time, Tanjiro expressed his reassurance at being with him and thanked him, reminding Inosuke Hashibira of the kindness his wife had shown him. Although he didn't quite understand the meaning behind it, Inosuke Hashibira realized that Tanjiro Zenitsu were both very caring and supportive partners.

Later, the two encountered Murata, a fellow member of the Demon Slayer Corps. Seeing that they were low-ranking swordsmen, Murata stated that they wouldn't be of any help even if they came. Finding Murata tedious, Inosuke Hashibira punched him and demanded an explanation. After learning from Murata that the team members' actions were being controlled by demons, Inosuke Hashibira immediately used his "Seventh Form: Spatial Perception" to locate his target—the "mother" of the spider demon family. However, all the surviving Demon Slayer Corps members had been killed by the spider mother because they were no longer of any use. Sensing Tanjiro's anger, Inosuke Hashibira understood for the first time the rage of having someone he cared about taken from him. Inosuke Hashibira and Tanjiro then joined forces to kill the spider mother and all her puppets.

After being placed in the middle, the two continued deeper into the spider family and encountered the "older sister" and "father. "Tanjiro was then knocked away by the spider father with a tree trunk, leaving Inosuke Hashibira to fight him alone. Although Inosuke Hashibira was initially evenly matched with his opponent, the spider quickly molted, greatly increasing its fighting power. Ultimately, Inosuke Hashibira was defeated and captured by the spider father, nearly being killed.

In the flashback, Inosuke Hashibira sees a memory of his mother throwing him into the river to save his life. At the same time, the Water Pillar, Giyu Tomioka, arrives just in time, beheading the Spider Inosuke Hashibira and saving Inosuke Hashibira. Seeing Giyu Tomioka easily defeat an opponent he couldn't possibly beat, Giyu Tomioka becomes extremely interested in him. Wanting to challenge Giyu Tomioka, Inosuke Hashibira starts making a scene. Annoyed, Giyu Tomioka simply ties him up and hangs him from a tree, leaving him alone. Seeing his utterly invincible opponent easily defeated, a depressed Inosuke Hashibira begins to feel weak and useless.

Upon seeing the Insect Shinobu Kocho, Inosuke Hashibira mistakenly believed she was the woman he had seen in the flashback, but because he had screamed and yelled while being hung up by Giyu Tomioka, he had lost his voice and had soon forgotten about the incident, thus failing to question her. (Hashira Trial Arc)

Inspired by Shinobu, Zenitsu undergoes treatment at the Butterfly Mansion with Tanjiro and Zenitsu. Having failed to defeat a single demon on the mountain and lost to a smaller girl during recovery training, Inosuke Hashibira Zenitsu Inosuke Hashibira, he rallied and defeated Aoi in training, though he repeatedly lost to Kanao Tsuyuri. Therefore, he refused to train anymore and instead went to play with the animals on the nearby Butterfly Mansion, making a mess of the carefully tended back mountain.

However, after Tanjiro completed his training, Inosuke Hashibira, encouraged by Shinobu's "reverse psychology," quickly completed the "Total Concentration - Normal Concentration" training together with Zenitsu.

In the Mugen Train arc, Inosuke, along with Tanjiro Yamato Zenitsu, boarded the Mugen Train with the Flame Hashira, Kyojuro Rengoku. However, upon seeing the train, Inosuke Hashibira, having never seen one before, mistook it for some kind of animal.

After boarding the vehicle, Inosuke Hashibira, like everyone else, was trapped in a dream due to the Blood Demon Art of Lower Moon One, Enmu. In the dream, Inosuke Hashibira saw Tanjiro and the others transformed into animals (Tanjiro as a tanuki, Zenitsu as Rat, Nezuko as a rabbit), while he became the leader of the group, embarking on an adventure together in a cave.

Afterwards, Enmu ordered several human subordinates to invade everyone's dreams via ropes, attempting to destroy the "spiritual core" within their unconscious realms, intending to cripple them before killing them. However, due to Inosuke Hashibira's overly strong self-awareness, he himself appeared within his own unconscious realm and attacked the intruders (as did Zenitsu). Subsequently, Enmu's Blood Demon Art was neutralized by Nezuko's blood, and Inosuke Hashibira, along with the others, awoke at Tanjiro's call.

After waking up crying, Inosuke Hashibira and Tanjiro stormed into the front of the train, intending to kill Enmu. During this time, the mask Inosuke Hashibira was wearing rendered Enmu's Blood Demon Art ineffective. Ultimately, the disoriented Enmu was defeated by Tanjiro 'Hinokami Kagura: Hiroten. Afterwards, Upper Moon Three Akaza suddenly appeared, and Kyojuro Rengoku bravely fought him to protect Inosuke Hashibira and the others.
