Top 10 famous quotes of Kyojuro Rengoku—one of the most beloved characters in Demon Slayer: Kimetsu no Yaiba
This boy is not weak. Do not insult him.Kyojuro Rengoku
The boy in question is Tanjiro, the protagonist.
During the battle on the Mugen Train, Tanjiro was unable to move when the Upper Rank demon Akaza suddenly appeared and attacked him.
Rengoku protected Tanjiro and spoke with Akaza.
When Akaza dismissed Tanjiro as weak, Rengoku denied it with these words.
On the Mugen Train, Rengoku focused entirely on protecting the passengers and left the demon-slaying to Tanjiro and his companions.
They lived up to his expectations brilliantly.
Because Rengoku acknowledged Tanjiro, he could not accept Akaza’s claim.
No matter how much you’re crushed by your own weakness or inadequacy, keep your heart burning.Kyojuro Rengoku
These are the words Kyojuro Rengoku spoke when he sensed his death approaching, addressed to the young members, including the protagonist Tanjiro Kamado.
Because they came from someone who lost his mother, grew strong enough to become the Flame Hashira, yet was never acknowledged by his father—someone who had every reason to despair but kept living with strength—they resonate deeply.
Even as he himself was about to die, he urged them not to give up on hope; I imagine many people were moved to tears by his final words.
Like him, even when we see reality for what it is and find ourselves on the brink of despair, we want to keep moving forward powerfully, without giving up.
Come! I’ll cut you down along with your grudges!Kyojuro Rengoku
These lines are what Rengoku shouted at a demon in “Demon Slayer: Kimetsu no Yaiba — Rengoku Kyojuro Gaiden.” At the time, Rengoku wasn’t yet a Hashira.
He attended the Hashira meeting in place of his drunken father, and from there was assigned to hunt down a member of the Twelve Kizuki.
The demon he encountered on that mission was Lower Rank Two, who bore a grudge against Rengoku.
For revenge, the demon had planted bombs all across the Imperial Capital and declared to Rengoku that the Demon Slayer Corps could never defeat demons.
But Rengoku remembered his mother’s words, spoke these lines, and charged forward.
It was a line that conveyed his unshakable resolve to defeat that demon once and for all.
I will fulfill my duty!Kyojuro Rengoku
Here is one of Rengoku’s famous lines, spoken even as he’s pushed to the brink in his battle with Akaza, while still trying to protect the passengers and Tanjiro’s group.
It doesn’t just mean he’s doing it because it’s his responsibility to protect everyone; it also conveys his wish to keep his heart blazing and to continue bearing responsibility by doing so.
And the unwavering resolve born of his strength—the determination to let no one die—is truly admirable.
For those who usually take life at a leisurely pace, it might be worthwhile to reflect on his strength.
This crimson flame blade of Purgatory will burn you to the bone!!Kyojuro Rengoku
https://www.tiktok.com/@anime_kimetsu_official/video/7512837942323203335This is the famous line Rengoku said when the demon hiding on the Mugen Train revealed itself.
Right before this, he says, “If you bare your fangs at the innocent,” which vividly conveys his strong sense of justice and overflowing confidence.
In fact, immediately afterward he uses Flame Breathing, First Form: Unknowing Fire, to behead the demon in an instant.
While his flashy appearance and slightly peculiar personality tend to draw attention, his skill ranks high even among the Hashira, and this line alone conveys Rengoku’s strength and his unwavering resolve to surely annihilate demons.
Don’t let yourself be swallowed by that sorrow; someday, it will surely become a precious strength.Kyojuro Rengoku
Hardship is something everyone experiences as they go through life, and there are moments when it can bring us to a halt.
These words convey how the difficulties before us can affect our future while also stirring the strength to move forward.
Above all, not letting yourself be swallowed by sorrow is what matters most; if you can manage that, you can turn it into the power to continue your life’s journey.
If you can remember these words, even a path that feels full of obstacles may be one you can walk with a positive spirit.
Aging and dying are the beauty of humans, a fleeting form of life.Kyojuro Rengoku
These words were spoken in response to an invitation to “become a demon” during the battle with Akaza.
Against the claim that, as immortals, demons can strive toward heights humans can never reach, they speak to the value of time precisely because human life is finite.
It’s because aging and death await us that we learn to cherish the time we have, and it is in living that way that true beauty lies.
It’s a declaration of choosing finitude over infinity, conveying a firm resolve and a gratitude for being able to live in the limited ‘now.’
