This won’t kill you at this level! Get down here, you fool!Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba
A famous line directed at Zenitsu Agatsuma as he screamed, “If I train any more, I’ll die!!!” and fled up a tree.
It conjures the image of Jigorō Kuwajima as a stern master.
The words acknowledge that training hasn’t borne fruit yet, but also recognize the disciple’s talent.
To Zenitsu, who wanted to escape the pain right in front of him, the master may have seemed like a demon.
It’s a line born of high expectations, yet it became one of the factors that made Zenitsu look back on the parts of his life he hated.
It’s okay to cry. It’s okay to run away. Just don’t give up.Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba
https://www.tiktok.com/@duffnes7/video/7265306725966810369A quote directed at Zenitsu Agatsuma, who cries that no matter how hard he tries, he can’t get results.
For those who want to meet expectations, who are putting in the effort, and yet still feel they can’t change, it may be a message that offers salvation.
As humans, we all have times when we complain in hardship or want to escape reality, but the message that as long as you don’t give up, you’ll grow little by little supports a heart on the verge of breaking.
It’s a stern yet gentle quote that spurs on Zenitsu, who often runs away from difficulties.
Zenitsu, you are my pride.Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba
Zenitsu has a hard time believing in himself.
Even so, through training under Jigoro Kuwajima, he mastered Thunder Breathing.
However, Zenitsu could only use the First Form of Thunder Breathing.
Meanwhile, Jigoro’s other beloved pupil, Kaigaku, was the only one who couldn’t use the First Form.
Kaigaku became a demon and was ultimately defeated after a deadly battle with Zenitsu.
The words said to Zenitsu came from Jigoro Kuwajima, who had already taken his own life by then.
Weren’t they words about how he himself couldn’t turn his blade of Demon Slayer toward Kaigaku, and about how it wasn’t a form he had taught, but Zenitsu’s own creation—Thunder Breathing, Seventh Form: Honoikazuchi no Kami—with which Kaigaku was defeated? They carry the feelings of someone who cares deeply for the gentle Zenitsu.
If you can only do one thing, master it completely.Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba
Of the six Thunder Breathing forms, Zenitsu Agatsuma could use only the First Form.
Jigoro used to praise him, saying, “If you can master even one, that’s more than enough,” but in the past he apparently blew his top over Zenitsu being able to use only one.
Even so, Zenitsu threw himself into the harsh training, yet still managed to master only the First Form.
These are the words Jigoro said to Zenitsu then.
Just as those words suggested, Zenitsu pushed a single skill to its absolute limits and created techniques only he could use, such as Thunderclap and Flash and Thunderclap and Flash: Sixfold.
He even unleashed the strongest Thunder Breathing technique against Kaigaku after he became a demon.
Believe in it—the days you endured hellish training. You will surely be rewarded.Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba
Zenitsu keeps up with his grueling daily training, even while grumbling and voicing his fears.
Because he was abandoned as a child, he believes that no one expects anything from him.
But only his master, Jigoro, was always on Zenitsu’s side.
He also sent Zenitsu warm messages.
Thanks to that, Zenitsu went on to develop a breathing style that only he could use.
And it’s not just Zenitsu—through daily effort, we can all power up compared to our past selves.
Zenitsu surely drew strength from Jigoro.
It’s an encouraging message that if you give your all, even in tough times, the path will open.
You’re fine as you are. If you can do even one, that would be fantastic.Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba
Zenitsu Agatsuma, a disciple who can only use the First Form of Thunder Breathing.
He sometimes ran away from Jigoro’s harsh training and even cried.
Being able to use only the First Form made him lose motivation and confidence at times.
Yet Jigoro never abandoned him—he always encouraged and supported Zenitsu.
The message in his words, “It’s enough if you can master one form,” acknowledges Zenitsu’s lack of dexterity and becomes a source of strength for him to move forward.
These are words we, too, should remember when we lose confidence and our motivation wanes.
Do you know how to forge a sword?Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba
This is a famous quote addressed to Zenitsu Agatsuma when he tries to run away from training, using the example of forging a blade to teach the importance of discipline.
It later continues, “A sword is forged by hammering and hammering, beating out the impurities and excess, raising the purity of the steel, and creating a tough blade.” It tells him that if he can only use one Thunder Breathing form, then by honing it thoroughly, it can become a weapon that won’t lose to anyone.
People tend to focus on their weaknesses rather than their strengths and try to work hardest on what they can’t do.
But this quote suggests that it’s our strengths that become a unique individuality no one else can imitate.
