A rift tears open over Taisho-era Japan and drops Son Goku — full power, zero warning — straight into the middle of the Demon Slayer Corps' endless war. No nerfs, no shortcuts: Goku's ki meets Nichirin steel, Sanemi's Wind Breathing, Muichiro's Mist, Mitsuri's monstrous strength, and finally Muzan Kibutsuji himself — a thousand-year horror that has never once been forced to run from a fight.

Until now.

Watch a Saiyan raised on planet-ending threats collide head-on with the strongest demon lord in history, in a story that stays 100% faithful to both canons from the first frame to the last.

🔥 What happens when the Corps' greatest enemy finally meets something that isn't afraid of him?
⚔️ Can raw Saiyan power actually end a war a thousand years in the making?
🌸 And what does Goku do once the fight is finally over?
