[DISCONTINUED] Two Runaways || Demon Slayer || Demon!Senjuro AU

(PLEASE READ THE AUTHOR'S NOTE AT THE END OF THE LAST CHAPTER. IMPORTANT)

⚠️ Please don't read this story if you haven't read the manga. I don't wanna spoil it for those who haven't. If you ever want to read the manga, I suggest you search up https://ww5.demonslayermanga.com ⚠️

Both Genya and Senjuro were only kids when they ran away. Genya, at the age of eight, ran away from his village after burying his dead family who were slaughtered by a demon (though he assumed it was a wolf). Senjuro was six when he ran away from his verbally abusive father and couldn't decide if he should go back or not, but got lost later on.

Genya and Senjuro soon meet each other and decide to stay with one another. They were then taken in by two adults with two loving daughters. As years go by, everything soon fell apart. The demon king known as Muzan Kibutsuji slaughtered Genya and Senjuro's new family (Senjuro included).

Senjuro had been turned into a demon while Genya had managed to keep him under control. They were sent to go to a man that will help them by their new mother (who later on died from blood loss after leaving a dying message for Genya).

With Senjuro now a demon, Genya vowed to become stronger to protect him from any demons or demon slayers. But what happens when they meet two others just like them? Will they team up? Who knows.
