10 Best Kokushibō Quotes from the Demon Slayer Manga & Anime

The Demons of Demon Slayer are a truly fascinating lot. They come in all shapes and sizes, and while they are evil in their demonic form, their backstories and their lives while they were human usually contain a tragic note that makes you sad for them. But there are also exceptions, and one such exception is the protagonist of this article – Kokushibō. The Upper-Rank One of the Twelve Kizuki, Kokushibō was the second strongest Demon in the lore, behind only Muzan. In that aspect, Kokushibō is one of the series’ most powerful villains (and characters overall) and one of its most interesting characters. And he definitely deserves an article of his own.

This list will include a total of the best 10 Kokushibō quotes you need to know from the Demon Slayer: Kimetsu no Yaiba anime and manga. The quotes are taken from various contexts and situations, and we have decided to list them here for you and also explain the context and the meaning a bit.

1. “The ugliness of not admitting defeat even though they took my head, chopped me up and crushed me. Living in disgrace. Have I lived hundreds of years for this? Was I so afraid of defeat that I became a monster? Did I want to be strong even if it meant eating people? Did I become this miserable creature because I didn’t want to die? No. Yoriichi… I just wanted to be you.”

Regardless of how vile and evil he was, regardless even of the fact that he was the Upper-Rank One who had betrayed the Demon Slayer Corps, Kokushibō was a former samurai and he had a sense of pride inside of him even after becoming a Demon.

Kokushibō would ultimately loath himself for what he had become, but his whole life was just one hollow competition with his brother, Yoriichi, who loved him very much and who did not want to compete with him, making Kokushibō’s fight a solitary one. He would ultimately find solace in death, but the whole thing was sad.

2. “Akaza’s presence is gone. He has fallen. Akaza… weren’t you going to defeat me? A path had open for him to attain further heights… but he renounced it himself. How exceedingly weak.”

Demons could sense other Demons, and when Kokushibō noticed that he could not sense Akaza, the Upper-Rank Three, anymore, he criticized him for being so weak and taking Muzan’s gifts for granted (note: Akaza had realized the error of his ways and decided to die by stopping his own regeneration). Ironically, while Kokushibō was really true to his beliefs initially, he would end his life in the same way as Akaza, not much later.

3. “The old and ugly creature that was once my little brother had pity for me. But… I wasn’t angry. Even though 60 years ago, he had been such an eyesore. The voice calling me “brother” was terribly hoarse. My brother had never shown the slightest emotion… so at the sight of him shedding tears, something welled up in me for the first time since birth. I was confused… at my own unexpected unrest. But I must kill… this part of me from when I was human… This old man of brittle flesh past his prime… He was a Demon Slayer, and I must cleave anyone who turns a sword upon me. But his odd sentimentality… disappeared the next moment.”

We have already talked about the fated duel between Kokushibō and Yoriichi, during which Kokushibō almost died but survived thanks to the fact that Yoriichi died of old age, standing on his feet, just as he was about to kill his brother. Kokushibō often reflected on that fight and its implication, knowing that it had shaped his life forever, especially in how he perceived his brother and their relationship. And this quote is a perfect example of that.

4. “Yoriichi… when you smiled, I couldn’t help it… but I always found it disturbing. And when we were talking about how there were no successors for the various breathing techniques you suddenly started viewing things with strange optimism and you smiled. In my conceit I believed that only our generation was special. I felt sick with disgust and irritation. What did you find so amusing? […] What is so amusing about imaging such a future? Just thinking about losing makes me boil with anger.”

Kokushibō was a character with a lot of anger. Although he could be perfectly calm and composed, even during a fight, when talking or thinking about his brother, all the negative emotions he had harbored against him since their childhood would easily come to light and show just how disturbed Kokushibō was. This quote is yet another ideal example of how and why Kokushibō’s relationship with Yoriichi shaped him into becoming the monster he would ultimately be.

5. “I could never grab hold of anything. Anything at all. I abandoned my home. I abandoned my wife and children. I abandoned my humanity. I cut down my descendants and abandoned being a samurai. But even all that wasn’t enough? You said that those who master their paths all reach the same place. But I never did. I could not see the same world that you did. Why could I not leave anything behind? Why could I not become someone known? Why are we so different? Why in the world was I ever born? Tell me… Yoriichi.”

Yoriichi and Michikatsu, as Kokushibō was called when he was a human, were twins, but all that Kokushibō ever felt for his younger twin was jealousy. Where Yoriichi had become a legend, Kokushibō, despite everything he had done (and he has done, from his own perspective, comparatively more than Yoriichi), had become a vile and detested villain who had nothing to hold on to but the hatred he felt towards his brother.

This quote is another great example of how the relationship between the two wins functioned.

6. “Be thankful for the blood… You are not allowed to spill even a single drop on the ground… for if you do… your torso and head shall have a sorrowful parting.”

And while we cannot deny that Yoriichi was always the focus when Kokushibō’s personality was concerned, it is also a fact that he was quite a layered character and that he had a lot to offer in terms of his personality.

He was a character with a lot of pride, and when he became a Demon, he was exceedingly loyal to Muzan. He considered Muzan’s blood a gift and wanted others to cherish it as well, which explains this particular quote and how it reflected both Kokushibō’s personality as well as his relationship with his peers.

7. “Only you are outside of the natural laws of this world. Only you won Gods’ favors and are living your life. I hate you. I want to kill you.”

You’ve guessed it – Yoriichi again. Well, it’s not what we’re implying that Kokushibō was obsessed with his brother, but he really was obsessed with his brother. His hatred and jealousy towards Yoriichi drove him. They fueled his anger, making him, thus, even more powerful, as the negative emotions increased his demonic powers in more ways than one.

Ultimately, when Kokushibō was concerned, it all came down to his brother and how his brother influenced him and his behavior, which is also evident in how he spoke and thought, as this list of quotes has shown.

8. “I should draw… or else it would be rude.”

But, as we have said, Kokushibō also had another side to him, a side that enjoyed the battle and demonstrated a certain warrior’s pride that had nothing to do with Yoriichi per se. This line was said to Muichirō Tokitō just as the Mist Hashira was about to engage the Upper-Rank One in direct combat.

We all know how what fight ended, but this quote tells us two things. First, Kokushibō was quick to underestimate his opponents, and second, he did not let anything get in the way of his warrior’s pride, which is why this quote is relevant.

9. “Didn’t I want to lose that much? Even though I turned into such an ugly monster.”

This was the moment, referring back to quote #2 of our list, where Kokushibō realized that he had become a true monster and that he did not want to live like such a monster. Regardless of all the hatred and jealousy, regardless of all the negative emotions he had experienced and harbored over the centuries, he realized that he had taken it too far and that he did not want to be a literal monster now that he had already become a metaphorical one.

This is why Kokushibō ultimately chose not to regenerate and allowed himself to die and join his brother in peace, finding solace in death.

10. “One who doesn’t get jealous of others is just lucky because they just haven’t met the one who got Gods’ favors, yet.”

And finally, we close off our list with another Yoriichi-related quote. This one is connected to quote #7 and explains the philosophy behind Kokushibō’s jealousy. It explains how and why he hated his brother and how he perceived Yoriichi, as well as himself, in comparison to him. Kokushibō had a deeply rooted hatred because he was jealous because he thought Yoriichi had received it all, but he did not. The truth was that he simply did not know how to appreciate what he had.
