ONI SLAYER
Amnesiac and lost, three mysterious youths appear out of nowhere, wielding a unique gift: the mastery of legendary combat styles known as "Breathing Techniques." Taken under the wing of the powerful Commander Kuyo, Tanjiro, Zenitsu, and Inosuke join the Shadow Slayers to defend what remains of humanity.
But during the cataclysm known as "The Awakening," as Yokohama is ravaged by flames, a colossal, multi-headed dragon tears through the heavens. In the absolute chaos, the trio is swallowed by a violent miasma vortex.
When they finally open their eyes, the world has changed forever.
Stranded near the fortified village of Mahoroba, they discover a horrifying truth: ten years have passed. They entered the portal as teenagers, but emerged as battle-hardened, twenty-five-year-old warriors. Yokohama has fallen.
Now adults in a post-apocalyptic future they don't recognize, they must adapt to Mahoroba's advanced tech, navigate deadly political factions, recover their lost memories... and exterminate the Oni down to the last one.
