Blonde_Prime
After Tanjiro and Daki shared a completely unforgettable night, they couldn't forget that moment, nor the fact that they were practically opposites-an oni and a demon slayer-but they will meet again and understand that, even though they are from different worlds, they complemented each other.
[Aside from the Oni, all the main characters who are minors in the original are over 18 here, and few events have actually changed.]
This is the English version of the story; I also made a Portuguese version of this story.
