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.

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!
