Demon Slayer: Kimetsu no Yaiba began serialization in 2016 and exploded in popularity after its anime adaptation in 2019, becoming a social phenomenon. The popularity grew even more after the theatrical release of the Mugen Train Arc in 2020, with domestic box office revenue exceeding 40 billion yen, surpassing the all-time record of Spirited Away, and global box office revenue exceeding 500 million dollars, making it the world's number one annual box office revenue in 2020. The appeal of the Mugen Train Arc, which has broken various records, lies in its stunning visual beauty, direction, and the many famous quotes uttered within the story. In this article, we've picked out some of the famous quotes from the main characters.

Rengoku Kyojuro's Famous Quote

"This crimson flaming sword of Rengoku will burn you to the bone!!"

Kyojuro confronting the demon on the train

This is the line uttered when confronting the demon that appeared on the train. With the dignified demeanor of the Flame Pillar and the subsequent First Form Shiranui, he quickly took down the demon. This was a dream dreamed by Enmu, but I'm sure many viewers were still captivated. The film version's background music and production are more captivating.

"I'm a failure as a Pillar! If there was a hole, I'd crawl into it!"

Kyojuro's line immediately after waking up from a dream

This line is spoken by Kyojuro after waking up from the dream Enmu had shown him, in the completely changed train car. Though ashamed of having been put to sleep, he quickly acted and rushed to Tanjiro's side from the rear of the train. In the process, he cut off Enmu's tentacles, slowing their regeneration. After quickly issuing instructions to Tanjiro, he singlehandedly defended the last five rows.

"If you master your breathing, you'll be able to accomplish many things."

Kyōjurō Teaches Tanjiro

This line is spoken by Kyojurō as he trains Tanjiro, who is seriously injured after defeating Enmu. Kyojurō's father, who was his master, became an alcoholic and stopped teaching, so he became a Hashira on his own. This line is particularly compelling because it comes from Kyojurō, who trained himself and overcame hardships to become a Hashira.

"Growing old and dying are the beauty of the fleeting creature known as humans."

Kyōjurō Discusses the Beauty of Humanity

This is what Kyojurō said when Akaza, who suddenly appeared, invited him to become a demon. Pursuing physical strength, Akaza invited Kyojurō, telling him that if he became a demon, he could train for hundreds of years and reach the highest realm, but he showed no sign of being shaken. His values differed from Akaza's, partly due to the fact that Kyojurō's mother was a woman who was extremely strong, not physically but mentally.

"I will fulfill my duty! I won't let anyone here die!"

Kyojuro, burning with heart, musters his last bit of strength

Kyojuro fought a fierce battle with Akaza, but the inextricable difference between demons whose wounds heal quickly and those whose wounds don't is clear, and Kyojuro is cornered. Akaza is without a scratch, while Kyojuro has a crushed left eye and broken ribs. Even so, Kyojuro refuses to give in, and stands up to Akaza with a burning fighting spirit.

"Come over here, let's have a final chat."

Kyōjurō gently speaks to Tanjiro, who exudes frustration

Kyōjurō, mortally wounded on the front lines, is pierced through the solar plexus by Akaza. Tanjiro curses Akaza for fleeing the scene, but Akaza disappears into the forest. Even as he lay on the brink of death, Kyōjurō gently speaks to Tanjiro, whose frustration is evident.

"Young Kamado, I believe in your sister. I accept her as a member of the Demon Slayer Corps."

The moment when Kyojuro, who was opposed to Nezuko joining the Demon Slayer Corps, finally believes her

At the time of the Hashira Meeting, Kyojuro was opposed to Nezuko joining the Demon Slayer Corps, but after seeing her fight on the Mugen Train, he accepted her as a member. In just under a day, Nezuko was able to change the Hashira's mind.

"Burn Your Heart"

Burn Your Heart

These are Kyojuro's final words to Tanjiro and his friends. While showing concern for Tanjiro and his friends, who were powerless in the battle against Akaza, he encouraged them not to give up and pushed them forward. These words symbolize Kyojuro's life, which continued to move forward even when his father, who had lost his mother, was unable to see the future due to grief.

Tanjiro Kamado's Famous Quotes

"I'm so grateful, and so sorry."

Tanjiro Says Goodbye to His Family to Awaken from His Dream

This is Tanjiro's state of mind as he parted ways with his family once again while escaping Enmu's cruel dream. Feeling guilty for being the only one to survive that day, Tanjiro decided to move forward and break away from his dream.

"You'd never say that! My family would do something like that!"

Tanjiro explodes in rage after having a nightmare in which his family is insulted

This line comes as Tanjiro explodes in rage after confronting Enmu and having a nightmare in which his family insults him. Enmu's actions, which trampled on Tanjiro's deep love and trust for his family, were more unbearable than anything else for Tanjiro. This was the first time that Tanjiro, who had previously shown some sympathy for demons, directed pure anger at them.

"Don't run away, you coward! Don't run away!!!"

Tanjiro barks at the fleeing Akaza

After fatally wounding Kyojuro, Tanjiro throws his sword at Akaza, who runs away from the sun as fast as he can, and barks this line with all his heart. Tanjiro could only watch, unable to move due to his abdominal wound and the side effects of the Hinokami Kagura. This line captures Tanjiro's feelings, a mixture of frustration and helplessness.

"It's so frustrating. Even if I manage to master one thing, there's always another thick wall right in front of me."

Tanjiro is overwhelmed with regret after Kyojuro's death

Kyojuro passed away after entrusting his will to Tanjiro and the others. This is what he said shortly after reuniting with Zenitsu. Tanjiro and the others had trained hard and grown little by little, but they were overwhelmed by the overwhelming strength of the Upper Rank Pillars, who were beyond their ability to defeat. However, it was at this point that Kyojuro's last words hit home.

Inosuke Hashibira's Famous Quote

"Charge headlong! Lord Inosuke has to get through!"

Inosuke appears breaking through the roof of the train after waking up from a dream

This is the line Inosuke said after waking up from the dream Enmu had, bursting through the roof of the train in high spirits. While Tanjiro and Inosuke hadn't worked well together in previous battles, they showed impressive teamwork in their fight against Enmu, successfully defeating him together.

"There's no opening, I can't get in. I can't keep up with the speed of their movements."

Inosuke watches Akaza and Kyojuro fight and understands the difference in their dimensions

Inosuke was less injured than Tanjiro and was able to move even when Akaza appeared. Normally, Inosuke would charge in headfirst, but the more he watched the battle between the Upperclassman and the Pillar up close, the more he realized the difference in their abilities, and he was unable to intervene to help.

"Don't be so weak-hearted!!"

Inosuke speaks to a devastated Tanjiro

These are the words spoken to Tanjiro, who remains devastated despite being entrusted with his will. While the words themselves are different, the meaning is the same as what Kyojuro left behind. Inosuke took Kyojuro's words to heart and decided to move forward. This scene also symbolizes how important Rengoku Kyojuro is to Tanjiro, Zenitsu, and Inosuke.

Zenitsu Agatsuma's Famous Quote

"I'll protect Nezuko."

Zenitsu rushes to the rescue despite still having woken up from a dream

This is a cool scene in which Zenitsu dashes to Nezuko's rescue despite still having woken up from Enmu's dream. Zenitsu is usually a comical character, but he showed his cool side in the Mugen Train arc.

"Why did an Upper Rank come? Are they that strong? No way..."

Zenitsu is astonished by the Upper Rank's otherworldly strength

Zenitsu was the only one who didn't see the fight between Kyojuro and Akaza. Kyojuro used techniques on the train to buy time, and even when the train rolled over, he used a powerful technique to minimize the damage. He was undoubtedly Zenitsu's strongest corps member. The despair he felt at losing such a member is immeasurable.

Akaza's Famous Quote

"Why don't you become a demon too?"

Recruiting Kyojuro

This is the line that Akaza uses when he appears before Tanjiro and Kyojuro after their battle with Enmu, inviting Kyojuro to become a demon. No matter what he says to Kyojuro, he refuses to accept the invitation, so Akaza declares that he will kill him if he doesn't become a demon, and he literally does.

"Even if you fight with the intention of sacrificing your life, it's all for nothing, Kyojuro."

Akaza reminds us of the difference between demons and humans

This line brings home the never-ending gap between demons and humans. Even with this realization, Kyojuro refused to accept the demon's invitation and instead faced Akaza with all his heart and soul.

"What is that brat talking about?"

Akaza becomes enraged at Tanjiro's words, even though he is a weakling

After fatally wounding Kyojuro, Akaza is insulted by Tanjiro as they flee from the sun. In fact, Kyojuro dies, while Akaza survives. However, Kyojuro's goal wasn't to win, but to prevent anyone from dying. This scene symbolizes winning the challenge but losing the match.

Enmu's Famous Quotes

"All human hearts are the same. They're as weak and fragile as glass."

Seeing through the Demon Slayer Corps' weaknesses

Enmu employs a vicious tactic unlike any demon before him, avoiding a head-on battle with the Demon Slayer Corps members and instead using underhanded techniques to render them unable to recover. He also employs roundabout techniques to make his spells difficult to see through. If even one of Tanjiro and his companions had been missing, they might not have been able to defeat Enmu.

"Falling asleep, falling asleep. Falling asleep, forgetting to breathe."

Enmu hums an eerie lullaby

Enmu hummed an eerie lullaby as he watched Tanjiro and the others under the spell. The happy dreams didn't just include pleasant ones, but also cruel ones, such as showing Tanjiro, who had lost his family, a dream of spending time with his family, making it impossible for him to resist even if he wanted to.

"What a miserable nightmare..."

Enmu suffers karma

Enmu continues to cause nightmares, but when Tanjiro and the others wake up, their plans are gradually foiled. Enmu's defeat can only be explained as bad luck, as all the people he didn't want to be together all gathered together. To him, Tanjiro and the others were nothing but a nightmare.
