Trained to live and fight in the shadows, Y/N is the elusive Shadow Hashira, a protector hidden from even her fellow Demon Slayers. Assigned a new mission, she's tasked with keeping an eye on the ever-flashy Sound Hashira, Tengen Uzui. But dealing with his relentless energy isn't her only challenge-Sanemi, the intense Wind Hashira, keeps crossing her path too. Now caught between Tengen's charm and Sanemi's sharp edges, Y/N finds her carefully hidden life turned upside down. Can she stay in the shadows, or will these two forces pull her into the light? It seems hiding won't be so easy this time. --- All rights go to creators of Demon Slayer, I only just make fanfic and I just happen to like Tengen and sanemi the most :p Cover art is from Pinterest, not mine!
