After repeatedly being enticed to become a demon, he declared to Upper Rank Three, Akaza, the famed line: “I will not let anyone here die!!” It’s a quote that embodies Kyojuro Rengoku’s way of life, grounded in his promise to his late mother: “Helping the weak is the duty of those born strong.” The resolve that fuels his power—so great that even the enemy Akaza praises it—is overwhelmingly compelling.

True to his words, not a single person under his protection was lost.

It’s a spine-tingling quote that validates Kyojuro Rengoku’s strength.

Why do they target the wounded first? I don’t understand.Kyojuro Rengoku

When Upper Rank Three, Akaza, attacked the injured Tanjiro Kamado, he declared the famous line: “I can’t understand why you’d target the wounded.” It seems to be a quote that symbolizes the clash in values between Akaza, who despises the weak, and Kyojuro Rengoku, who believes the weak should be protected.

Even today, in sports and martial arts, there’s the standard strategy of targeting an opponent’s weaknesses, but there’s also a certain beauty in facing someone head-on with fairness.

It’s a memorable line that conveys a conviction to protect the weak, even in a battlefield where lives are on the line.

Don’t worry. I will definitely save you.Kyojuro Rengoku

Rengoku headed to the maintenance workshop where the Mugen Train had been moved and, saying he’d come with a small gift, he spoke with the foreman.

Then a scream rang out; when he rushed to the back, he found a demon holding a boy hostage.

Terrified, the boy pleaded for Rengoku’s help.

In response, Rengoku answered with these words.

The demon was so fast that a careless swing of the sword could injure the boy as well.

In such a situation, being able to say “I will definitely save you” is proof of Rengoku’s strength, isn’t it? It’s just plain cool!

Let’s work hard together as pillars.Kyojuro Rengoku

The Mist Hashira, Muichiro Tokito, was told the famous line, “Let’s do our best together as Hashira,” when he first became a Hashira.

While acknowledging that he was a genius swordsman who rose to the rank of Hashira just two months after taking up a blade, the line also seems to show consideration for Muichiro, who was younger than himself.

Moreover, since Kyojuro Rengoku has a younger brother, Senjuro, it may have been hard for him to just leave Muichiro alone.

The scene that Muichiro recalls when he regains his memory is stirring, and this quote makes you feel Kyojuro Rengoku’s straightforward kindness without any pretense.

It’s an honor to have been able to protect you, just like my father.Kyojuro Rengoku

In response to being told by Tomi from the bento shop that he’d been saved 20 years ago as well, he replied with the memorable line: “It is an honor to have protected you, just as my father did.” His father, Shinjuro Rengoku, is a man who drowned himself in drink and treated his son coldly, yet Kyojuro unconsciously imitated his mannerisms and was influenced to the point of being mistaken for him.

This scene shows just how much Kyojuro Rengoku respected his father.

It’s a quote that makes you feel how deeply meaningful it was to Kyojuro that he could save the same person his father once saved.

We will take the time to tend even to the hardest-to-heal wounds of the heart!Kyojuro Rengoku

The demon at the maintenance shop was called the Ripper.

The reason was that if he thought a person’s blood tasted bad, he wouldn’t eat them—he would just cut them to pieces.

The demon bragged to Rengoku that he had sliced up a certain woman the night before, but Rengoku replied that she was alive and under their protection.

The demon then said that even if she lived, she would spend the rest of her life ruled by fear.

In response, Rengoku declared these words to the demon: Not only will we slay demons—we will also tend to the hearts of those wounded by them.

It was a wonderful line that conveyed Rengoku’s kindness.

I will never let go. Not until I cut off your neck!!!Kyojuro Rengoku

During the battle with Upper Rank Three, Akaza, he shouted this famous line at the demon as it tried to flee from the lethal morning sun: “I will never let go—not until I’ve cut off your head!!!” Despite having his vital point pierced by the enemy’s right arm, his determination to fulfill his duty exudes the true intensity of a Hashira.

It also connects to Kyojuro Rengoku’s resolve to be strong and kind, inspired by his mother.

This quote brings tears as it portrays his willingness to risk his life to protect those he holds dear.
