The endings of the Red Light District in Kimetsu no Yaiba show that: Nezuko’s Blood Blast is the biggest “counterweight” to Muzan.
Muzan is the main antagonist in the entire Kimetsu no Yaiba series. Legend has it that he has lived in this world for thousands of years. And the amount of crime he committed is immeasurable. 70% of the demons that exist here were created by him. They slaughtered countless innocent people just to find food. And among the demons, the most aggressive, powerful, and cunning will be included as the Twelve Moon Demons. Even the Pillars must be somewhat afraid of them. But perhaps, they are slowly running out of time.
The reason for this is not so strange. It is something very familiar to every Kimetsu no Yaiba fan. Or to be more precise, Nezuko and her Blood Demon Bleeding Magic. Perhaps from the beginning of the work, it was something too different. Instead of eating human flesh to recover, she did this by going to sleep. Instead of losing its morality because of its bloodlust, it still knows how to love people. And finally, instead of using Blood Demon to kill people, Nezuko “created” Blood Blast with only one purpose: to burn demons.
This flame can be adjusted to Nezuko’s discretion. Which means she can choose exactly what to burn.
Basically, Blood Blast is a move that requires Nezuko’s blood. This blood demon allows her to burn anything at will. To do that, she would think about what she wanted to burn. And the fire will only generate heat to burn only that object. In most cases, what needs to be burned will be the demons under Muzan’s command. Demons that are “baked” by her will have a hard time recovering from their wounds.
Not only that, it can completely destroy exactly the “trace” of the demon on the victim’s body. For example, Enmu’s curse line or Gyuutarou’s poison. Thanks to that, both Zenitsu, Inosuke and Tengen were saved.
If they can make good use of Nezuko’s Bleeding ability, the good side will gradually return to the upper hand on the “balance” of the world Kimetsu no Yaiba. With the ability to burn all the “remnants” of demons, it will bring a lot of advantages. Just taking a direct hit, Daki has burned to the point where it’s hard to recover. Now, if you use it in the right “place”, it can be easy to kill demons. I’m afraid even Muzan wouldn’t take it lightly.
Most likely, if they burned all the demon blood in the people who had just been injected with demon blood, they would still be healthy
In Game4V’s opinion, Nezuko’s Blood Blast preventing the demonization process is completely grounded. Suppose when she finds out that someone is about to be turned into a demon. Just burn all the “remnants” of the demons in them and it’ll be fine. Rest assured that this fire burns accurately so the victim does not feel pain. Moreover, if we spray it on weapons, we will create super hot weapons. Just looking at it, demons are more afraid of fire than you think! They heal quickly from many types of wounds. But this probably doesn’t apply to burns. Just by being cut with them, the cells around the wound would be burned to cinders. That would be very difficult to recover, even the Demon Lord was no exception.
Then why does she have this special ability? It was because of the connection between the Kamado family and the Sun Worshiping Steam. This family has a special connection with the sun for hundreds of years. That was probably the reason why Nezuko possessed the Fire-type Blood Demon magic. And that could also explain why she’s still human after being bitten by Muzan
