Set in a Sabito-lives AU, Flow Like Water, Burn Like Fire follows Giyuu Tomioka and Sabito from the age of eight to eighteen as they train under Urokodaki, survive deadly missions, and grow from frightened children into formidable Demon Slayers.
Bound by shared loss, relentless training, and unwavering trust, the two learn how to fight side by side-water flowing steady beside fire that refuses to burn out. Across years of battles, failed missions, hard-won victories, and whispered promises beneath the stars, their bond deepens into something neither of them can ignore.
This story explores growth, loyalty, trauma, healing, and love, chronicling the adventures they survive, the demons they defeat, and the names they earn-together.
A slow-burn coming-of-age story about choosing to live, choosing to fight, and choosing each other in a world that takes far too much.
