What Kaguya Actually Did: More Than Just Vengeance

Contrary to popular depictions focusing solely on her demon-slaying prowess, Kaguya’s actions were driven by a profound, resolute vision: to elevate humanity’s existence beyond mortality and cruelty—no matter the cost.

Here’s what stories and lore reveal about her decisive choices:

1. The Battle of Muken: Testing Humanity’s Spirit

Final Thoughts

Rather than simply annihilating demons, Kaguya fought the Demon Hashira not to destroy, but to test and refine humanity. She saw mortal fragility—not strength—as the key to true evolution. Her brutal battlefield encounters were not only tests of power but existential challenges: Can humans endure suffering and rise wrapped in compassion?

2. Gift of Life: The Birth of S vanilla’s Transition

Kaguya’s ultimate act emerged in her nurturing of Tanjiro’s surrounding realm. While not directly creating S-key DNA, her influence catalyzed the development of transformative life forces—from Senjutsu to the Demon Slayer curse. Her sacrifice paved the way for humanity’s rebirth as sentient beings shaped by will, not pure blood.

3. Brood Mother of the Moon and His-Like Destiny

Peeling back her psyche, Kaguya’s motivations appear deeply maternal and cosmic. She recognized her own powers as a bond to humanity—and saw her “offspring” as vessels for a new age. Her rivalry with Hashira Hashiro was less about conquest, but about fostering freedom over obedience—a quiet rebellion against divine tyranny.
