I was traveling through a small village, book in hand, lost in diagrams and notes on demon physiology and alchemical research.
The villagers gave me wide berth, whispering as I passed, but I paid them no mind. Their lives were trivial in comparison to the work I had ahead.
I turned a corner and froze—not out of fear, but recognition.
A modest wooden house, simple yet sturdy.
The Kamado home.
I frowned slightly.
Five hundred years before its most famous occupant would ever be born. Tanjiro Kamado.
I wasn't here for nostalgia or curiosity. I was here for preparation.
According to what little I had gleaned from the story of Demon Slayer, something peculiar grew around this home. A plant. A flower. The blue spider lily.
I spent the next two days investigating, careful to leave no trace. I observed the land, tested soil, and monitored patterns of sunlight. At first, nothing happened. Then, on the first light of dawn, I saw it.
A single blossom unfurling, fragile yet impossibly resilient, bathed in golden rays.
It was almost laughably ironic. A flower that grew for only a few minutes each morning. So fleeting, so delicate… that no demon could ever hope to take it. Nature itself had prepared the Kamado bloodline with a defense the world would only understand centuries later.
I harvested a few blooms carefully, preserving them in magically reinforced vials. Their properties were unlike anything I had seen: resilience encoded at a cellular level, compounds capable of accelerating regeneration, stabilizing cursed energy, and surviving in near-impossible conditions.
This was not just a plant.
This was a tool.
A weapon.
I set up a temporary residence nearby—a modest building transfigured from an abandoned structure. It would serve as my research hub.
Here, I would study the blue spider lily. Its biology. Its magical resonance. Its potential to augment my work with demon blood.
I stepped back and surveyed the surrounding land. The morning sun glinted off the lily's petals. Only minutes of life each day, and yet… immense power lay in those few fleeting moments.
A fitting metaphor.
If I wanted to outlive demons, outwit Muzan, and eventually face the apex predator of this world, I would need every advantage nature could give me.
And so, my work began anew.
The blue spider lily was mine.The future, already unfolding beneath its fragile petals.
