Chainsaw Man chapter 210 has cemented Yoru’s powers, and maybe is building up on her true personality. In a single chapter, Fujimoto turns the War Devil into something far scarier than any Primal Fear.
He gives her everything she’s ever wanted, not due to a protagonist's failure or some forbidden seal breaking, but because America did what it always does: build weapons. And in doing so, Yoru becomes powerful beyond imagination.
The chapter opens in the aftermath of Yoru’s climactic battle with the Falling Devil, a Primal Fear. At one point, Yoru was clearly outmatched. Falling, as a primal embodiment of a universal fear, seemed nearly unbeatable. But in Chainsaw Man Chapter 210, that imbalance is erased.

With an almost theatrical flick of her fingers, Yoru turns the Falling Devil into a set of clothes. This moment is striking not just because of the sheer absurdity and brutality of it, but because of what it symbolizes: Yoru has ascended. Her power has reached a peak we previously thought impossible. If a Primal Fear can be woven into a cape, who, then, can stop the War Devil?
But this power-up doesn’t come from within Yoru. It’s not the result of emotional growth, a fusion with Asa, or some dormant ability. Instead, her new strength is a direct result of America’s decision to drop nuclear bombs.
America’s role in the resurrection of nuclear power in Chainsaw Man Chapter 210

Here lies the most hauntingly brilliant part of Chainsaw Man Chapter 210: Yoru becomes powerful because America reinvented nuclear weapons from scratch. Up until now, we knew that Pochita (Chainsaw Man) had devoured the Nuclear Weapons Devil, effectively erasing the concept from the world. Yoru’s early motive in Part 2 even revolved around making him “vomit” it back up.
Yet, in a disturbing twist, Chainsaw Man Chapter 210 reveals that the devil wasn’t resurrected through any devilish act; rather, it came back because America built nuclear weapons again. The concept returned because humanity re-created it. In Chainsaw Man’s universe, devils are born from fear. If people forget a concept, its corresponding devil dies.
But America didn’t need help from a devil to restore nukes. The country rebuilt them from the ground up, not out of memory, but out of military ambition. Fujimoto presents this as both horrifying and sobering: humanity’s capacity for destruction doesn’t need supernatural aid. It’s self-sustaining.
Yoru’s “Love” for America isn’t patriotism: It’s power lust in Chainsaw Man Chapter 210

Upon realizing that America has remade nuclear weapons, Yoru bursts into laughter. She doesn’t mourn the loss of life in Russia. She doesn’t even marvel at the human ingenuity that made it possible. She simply says:
“I don’t love Denji. I’m in love with America.”
To her, America is not a nation but a conduit for carnage, a symbol of unchecked war-making potential. She loves America not for its ideals or people, but for what it gives her: power, terror, and attractiveness. She becomes stronger, more fearsome, and by her own account, desirable.
This statement is biting satire aimed directly at the Western romanticization of war. Through Yoru, Fujimoto critiques how America’s identity is so deeply tied to its military dominance that even the War Devil considers it the most attractive quality. It’s a moment that should disturb and provoke readers, especially American ones.
Final thoughts
There’s no subtlety in Chapter 210. Fujimoto’s criticism is raw and direct. America’s role in global violence, its legacy of nuclear warfare, and its cultural romanticization of military power are all laid bare in the pages of a shonen manga. Chainsaw Man Chapter 210 isn’t about shock value. It’s about moral confrontation.
