When tragedy steals everything from Y/N, she rises as the Water Hashira-unyielding, scarred, and sworn to fight until the last demon falls. But fate twists her path into the gaze of Obanai Iguro, the Serpent Hashira-stoic, sharp-tongued, and bound by shadows darker than his scars. What begins as rivalry on the battlefield becomes an unspoken bond of perfect synchrony... and a love forbidden in a world where tomorrow is never promised. Beneath the serpent's gaze, can two broken souls carve out a future together before the darkness consumes them both? ⚠️ Warnings: • Mature/NSFW themes (18+ ONLY - minors do not read) • Graphic violence, trauma, and emotional intensity • Heavy spoilers for Demon Slayer: Kimetsu no Yaiba • Angst, passion, obsession, tenderness tangled with ruin Best Rankings 🥇: #1 in Obanai #1 in iguro #1 in tengenuzui #2 in demonslayer #1 in giyu
