Demon Slayer: Kimetsu no Yaiba’s Hashira Training Arc has just finished, acting as the prelude to the end. There’s a controversy over its pacing (namely that it streeetches out what is a brief section of the manga despite relatively little source material), but I’d like to put that aside to talk about what I think is the most important moment from the season—one that highlights a core aspect of the main antagonist, Kibutsuji Muzan.

In the final episode of the Hashira Training Arc, Muzan confronts the head of the Demon Slayer Corps, Ubuyashiki Kagaya, who is bedridden and not long for the world. The eternally youthful Muzan mocks Ubuyashiki for his physical deterioration, only for Ubuyashiki to speak about Muzan’s obsession with his own immortality. The demon slayer leader juxtaposes this obsession with the driving animus of the Demon Slayer Corps: though it may consist of mortals, their collective will to defeat the demons lives on. In contrast, the demons rely entirely on Muzan for their continued existence. If he perishes, so too will they.

There lies the inherent opposition between the group structure of demon slayers vs. demons. Muzan has created a system where he alone holds all the cards, going beyond even the most tyrannical despot. And not only does he view his minions as property, he is unwilling to cede any degree of power to them if it is not under his full control. Whereas Ubuyashiki’s followers come to respect him for his compassion and determination, the demons cower in abject fear of Muzan because they are nothing without him. The Demon Slayer Corps legacy carries on, and not simply through childbirth. Instead, it is accomplished primarily through teaching and raising the next generation to be better.

The difference between Ubuyashiki and Muzan comes down to selfishness. It’s the boss who expects everyone to be at their beck and call, the narcissistic parental figure who demands their children listen to them just because, the political leader who passes laws to benefit themselves rather than their citizens. It didn’t have to be the case that toppling Muzan ends the demons, but the man set it up that way, mistakenly believing his weakness to be strength. As we now await the final movie trilogy to conclude Demon Slayer, I’m interested in seeing how this all plays out.
