Mount Fujikasane breaks through the cloud-veil, a divine Olympus where the Hashira hold court as gods. Lord Ubuyashiki governs the realms of family and devotion, while the sun of Yoriichi blazes and the moon of Michikatsu casts its silver glow. Far below, demigods like Tanjiro and Zenitsu train under that watchful light, their paths whispered by nymphs. The Underworld waits in the deep, ruled by Muzan and his Seven Sins. The very air thrums with celestial power and the promise of a war to come.
