Sun Chaser And Firework Maker

In a blink of an eye, Hanabi's life went up in flames and she was left for dead in a dark valley. As the world began to close in on her though, she saw through the haze of death and clung to life just long enough for the sun to rise and for a young Demon Slayer, Rengoku Kyojuro to find her on the brink.
