A/N: i saw some people doing a half demon half human (y/n), so i deiced to use the idea as well! the concept of a half human half demon (y/n) with a human mom and and a demon dad (muzan). i give full credits to original owner of this idea!
i also do not own demon slayer or its characters! only the book and (y/n).
