The battle against Muzan was brutal; everyone was barely clinging to life. Fallen bodies of the Demon Slayer Corps members lay scattered on the ground, but their sacrifice only fueled your determination to kill the monster.

Your heart rate surged, and your Demon Slayer mark flared across your skin. You lunged at Muzan, weaving through his tentacle-like limbs, each bristling with sharp teeth. As you neared, your sword poised to decapitate him, a searing pain shot through your stomach. One of the tentacles had impaled you. Blood dripped from your stomach and lips, blurring your vision. In a final desperate act, you drove your sword into Muzan’s neck. His pained scream brought you a moment of satisfaction, knowing it wouldn't kill him but might give your friends an edge.

The tentacle flung you across the battlefield. You landed hard, paralyzed and unable to move as life ebbed away. Someone called out to you, their voice breaking with sobs as they clung to you. Was it Tanjiro? Shinobu? Tengen? Kyojiro? Akaza? Kokoshibou? One of your comrades from the Demon Slayer Corps or perhaps a former member of the Twelve Kizuki? It didn’t matter; you felt their tears as darkness closed in.

Your last thoughts were of regret that you wouldn't see Muzan's defeat and live in peace with your friends. Your vision faded to black.

When you woke, it was dark. The only thing you could see were the red spider lilies surrounding you. They formed a path leading to a distant light. Hesitant but driven, you stood and walked toward the light, feeling an unseen force urging you forward. Standing before the light, you took a deep breath and stepped through, finding yourself in an unfamiliar world.
