Soooo, we all know that Rui never succeeded in taking Nezuko with him, but…

What if he did..?

Rui still had the headlock on Nezuko, she tried to fight back but was too weak to. Tanjiro tried to save her but he couldn’t…

He got killed by the red spider webs Rui trapped him in…

After that, he took Nezuko with him and killed Inosuke, Zenitsu, Shinobu, Giyuu and all the other humans in the forest. He then hypnotised Nezuko into thinking that he and the others were her family (though he’ll have to find a new mother, father and brother since Tanjiro, Inosuke and Zenitsu killed those 3).
