The best you will find are theories but then again, I don't give a rats ass about theories, I rather have the manga/anime explaining properly these types of big events since they are game changers and some theory won't cut it for me. Demon Slayer simply suck ass at explaining things and this isn't the only time it happened, Demon Slayer leaves things unexplained or half-assed, it also happened with:
*The sword changing colors, and why Tanjiro's sword is black, was never explained
*Tanjiro seeing the ghosts of dead people and even communicating with them
*Tanjiro having good smell
*Zenitsu having good hearing
*The eating demon gun guy gaining demon powers
etc...
In my opinion, some of the above issues could be fixed like this, Tanjiro's sword turns black because, for some reason, he has some affinity with the dead, so he's able to see the ghosts of dead people and he can even communicate with them. It sounds silly, but at least it's an explanation for his sword turning black, seeing ghosts, or communicating with them, I find this explanation better than leaving them half-assed.
While I can't speak of Genya's ability or Tanjiro's sense of smell, the black blade is pretty much self explanatory. The nichirin swords are made with ore that absorbs the sun. Depending on the breathing style of the user they change color. Sun breathing is the original breath with all other breaths being only a part of it. Black is a color that absorbs all light with all other colors only absorbing part of the light.Ant3290 said:No they don’t explain it properly and while medicine lady did say that Nezuko’s blood is constantly changing, it still doesn’t change the fact that it’s LAZY writing. “Nezuko blood is changing” is so vague, that could mean a lot of different things and doesn’t justify her surviving the sun. Nezuko was literally BURNING in the sun then as soon as Tanjiro turned around she was miraculously healed. So you mean to tell me her blood morphed so rapidly that she would survive being SCORCHED from the very same sun that was burning her alive 2 minutes earlier?? No, absolutely not. Anyone who says this isn’t an ass pull is delusional.
Tamayo sees that Nezuko's blood is changing but she can only speculate on why. If burning in the sun is a curse placed on demons for killing and eating humans then it stands to reason that one possible way to break the curse would be to sacrifice yourself for humans. And what is Nezuko shown doing between her "burning in the sun" and being "miraculously healed"? Just because the answer isn't spoon fed to you doesn't make it an asspull.
