Demon Slayer: Veil the Heavens with Mist, Beginning at Mount Fujikasane

A modern college student transmigrates to the Taisho era and takes over Muichiro Tokito's body. Faced with the tragedy in the original story, destined to leave nothing but devastation in its wake, he looks down at his fourteen-year-old body, a vessel for a prodigy, and falls into deep thought. As a descendant of the Tsugikuni line, he awakens to mastery of Sun Breathing, but the influence of his college-student soul leads him to choose a completely different path of training.

On the surface, he's the youngest and worst member of the Demon Slayer Corps.

In secret, he's the one true god who will reshape the world's order.

“Since I've been given another life, I'll keep those flowers that were never meant to wither here in this world.”
