Zenitsu Agatsuma’s Famous Quotes: Words that resonate with a heart that grows stronger while accepting weakness (1–10)
Even after they’ve cut your neck, don’t give up—go on the attack!
This is a line from Zenitsu during the Entertainment District Arc while Tanjiro and the others are fighting Gyutaro and Daki.
They realize the demons can only be defeated by cutting off both of their heads, so the group splits up to battle them.
However, they don’t actually need to decapitate them at the same time; even if Gyutaro’s head is cut off first, they should keep going and aim for Daki’s head as well—so he says.
In response to this smart idea, Inosuke, clearly surprised, blurts out, “Hey, you’re kind of seriously on point right now!” It was a memorable scene—cool, yet funny enough to make you laugh.
Kick me in the back!!!
These are the words Zenitsu chanted in his heart when he tried to muster his strength.
The person he wished would kick him into action was his master, Jigoro Kuwajima.
Zenitsu was timid and ran away during training, and each time Kuwajima would drag him back by kicking him or rapping him on the head.
From the outside it looked harsh, but Zenitsu adored Kuwajima as someone who would never give up on him, and he even felt affection in being scolded.
That’s why, at the crucial moment, he pictured Kuwajima and wished for him to fire him up.
I will protect Nezuko-chan.
In the Mugen Train Arc, when Nezuko was in danger, Zenitsu appeared with Thunderclap and Flash, cut down the demon, and said this line.
Although he was under the demon’s spell and not fully conscious, he sensed Nezuko’s peril and came to help her.
While Zenitsu is often seen as a cowardly character, it seems he shows his true strength when it comes to girls—especially Nezuko.
Also, because he’s stronger when he’s asleep, he was like a completely different person from the guy who had wanted to get off the train earlier! I bet many people’s hearts skipped a beat.

I’m the one who likes myself the least.
https://www.tiktok.com/@sanemi_0820/video/7468945120818122001At Mount Natagumo, where Lower Rank Five, Rui, lives, Zenitsu ends up fighting the Elder Brother Spider.
However, on his way there he was stung by a spider and poisoned, and when this is pointed out to him, he panics.
He runs away from the spider and ultimately flees up a tree in tears.
While being laughed at by the Elder Brother Spider, Zenitsu says he hates how weak he is and wants to become a decent human being.
It’s the first time he speaks honestly about his true feelings in this line.
And just when it seems like he’ll rally himself and fight… he faints.
Tanjiro… I… protected it… because you said… this is something… more important than life…

After defeating the former Lower Moon demon in the Drum House, Tanjiro steps outside.
There he sees Zenitsu, beaten to a pulp after being kicked by their fellow Demon Slayer, Inosuke.
Noticing that Tanjiro has come out, Zenitsu says this line.
Zenitsu has keen hearing and can distinguish humans from demons by the differences in sound.
So he knew from the start that Tanjiro was traveling with a demon.
However, because Tanjiro had said that the box containing Nezuko was ‘more precious than life,’ Zenitsu put his body on the line to protect it from Inosuke, who had realized Nezuko was inside and tried to cut her down.
I absolutely have to be the one to do this.
These words express Zenitsu’s resolve and tie into the episode of Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle Arc, Chapter 1: Akaza’s Return.
At the time, Zenitsu was training with Tanjiro under the Hashira Gyomei Himejima.
Then a letter arrived.
It likely contained news of their master Kuwajima’s death.
Because one of his disciples had become a demon, Kuwajima took responsibility and committed seppuku.
Tanjiro worried about the downcast Zenitsu, but Zenitsu spoke this line and quietly reflected on what he had to do.
Even if it hurts or is painful, don’t run away to the easier path.

♪ Original song – p – p
While fighting the spiders on Mount Natagumo, Zenitsu is injected with poison and his body grows weaker until he can no longer move.
In that moment, he recalls the words his master—Grandpa—gave him and murmurs, “If I give up, Grandpa will smack me,” as he uses his breathing to try to slow the spread of the poison even a little.
During this battle, Zenitsu remembers many events from his training days.
Seeing this, you can understand Zenitsu’s feelings and what he carries inside.
