A collection of quotes from Lord Ubuyashiki Kagaya. Words of unwavering resolve and salvation (1–10)
The resolve to never forgive those who unjustly took the life of a loved one is eternal.
A famous line that directly rejects the claims and very existence of Muzan Kibutsuji, progenitor of demons: “The resolve to never forgive those who senselessly stole the lives of our loved ones is eternal.” Most members of the Demon Slayer Corps have lost family or lovers to demons and had their lives thrown into chaos.
That hatred gave rise to people who would never otherwise have become swordsmen, and it is precisely what is now driving demons into a corner—so the line asserts.
Later, when Kagaya Ubuyashiki carries out his plan to raise morale, the weight of these words grows even heavier.
Eternity is the will of people. It’s human feelings that are truly eternal and indestructible.

While searching for each other, he finally came face to face with Muzan Kibutsuji and delivered this famous line: “Eternity is the will of humans.
It’s human will that is eternal and indestructible.” It’s a line that speaks to the futility of targeting Nezuko Kamado in pursuit of eternal, undying life.
Even if one’s life comes to an end, their will is passed down to future generations and will not vanish until their purpose is fulfilled—a message made all the more convincing coming from a clan that has fought demons for a thousand years.
It’s a quote that highlights the stark difference in values between demons and humans.
Amane, thank you so much for everything up to now.

As his condition worsened and he was unable to attend the meeting, his wife Amane participated in his stead and reported on its proceedings.
These are the words Yoya addressed to Amane.
They convey his gratitude for always being by his side—despite being tormented by a curse and facing a difficult path, with the support of their comrades, she remained his constant support.
It’s striking how his words sound almost like a final farewell, even though the battle is still far from over.
While leading the Demon Slayer Corps, he still expresses his thanks with earnest sincerity, and you can clearly feel his character in that straightforward gratitude.
Quotes of the Master, Kagaya Ubuyashiki: Words of strong resolve and salvation (11–20)
Welcome, my cute little swordsmen.

These are the words Yoya Ubuyashiki spoke to the assembled Hashira during their meeting.
Delivered as if a parent were speaking to their children, they convey a familial bond of trust between him and the Hashira.
Even within that trust, the fact that he stands as the parent and they as the children highlights the hierarchy in the room—an important point.
With this single remark, you can see the nature of the relationships among the characters in that scene.
It’s a statement that carries both the strength of a leader and a sense of affection.
I can’t prove that there’s no guarantee they won’t attack people. But I also can’t prove that they will attack people.
There is a quiet, probing line spoken by the leader who supports the Demon Slayer Corps—the Master—during the Hashira meeting about Nezuko: “We cannot prove a guarantee that she won’t attack humans, but neither can we prove that she will.” These words express the Master’s calm perspective and deep compassion, acknowledging that we cannot deny the possibility that Nezuko, even as a demon, may not attack humans and is not bound by her past.
It’s a line that truly resonates with the fighters who struggle in the harsh world of the Demon Slayer Corps.
Could you patiently talk to them so they can look forward (move on)?
These are gentle words spoken by Kagaya Ubuyashiki to Tanjiro, conveying his wish that Tanjiro be there for Giyu.
The key point is that he doesn’t use direct expressions like “help” or “support,” but instead emphasizes “listening,” which also communicates the importance of understanding the other person.
Along with his concern for Giyu, you can feel his trust that Tanjiro will be the one to help Giyu overcome his past.
By choosing not to do everything himself and entrusting things to his comrades, Ubuyashiki also demonstrates qualities befitting a leader.
When you regain your steadfast self, you can become even stronger.
These are the words Muichiro Tokito remembered during the battle—words once spoken to him by Kagaya Ubuyashiki.
It’s a situation where words he didn’t understand at the time now resonate with persuasive force, and through that we can see Muichiro’s growth.
The fact that he unleashed his strength the moment he became aware of the path he should follow, just as those words suggested, also shows how deeply Kagaya understands his comrades.
They’re words that convey, with clarity, the direction of growth suited to each individual, and in that sense they also reveal his qualities as a leader.
