A Demon's Blood Oath (Grandson of Inuyasha M!Reader x Demon Slayer)
23 parts Complete "Do you promise...?"
"I promise..."
Y/n, less than a quater demon, and more human then not, has been alone most of his entire life. Besides the Kamados' and his sister, he's never really been close to anyone. But life isn't fair, and the smell of blood tends to grow every second. Killed, murdered...no...Slaughtered, that's what the Kamados' were. But Tanjiro, Nezuko, and Y/n are determined to turn Nezuko back and hunt down the killer.
For that to happen, Y/n must embrace his demon side and harness the power of the Tessaiga. But can he stay in control? Or will he lose himself to his demonic bloodline?
(Disclaimer: If you couldn't tell, this is a cross over of both franchises. Meaning stuff like Demon Energy and stuff from Inuyasha will be in this story)
