How can Nezuko from Demon Slayer survive without eating?

Fans can say that Nezuko Kamado is the most adorable demon in the whole world. Murderer of demons. It may not be part of the 12 Demon Moons, but it has the potential to overpower a higher ranked demon with ease.

Unlike other demons that survive on blood, Nezuko never really needs it, and doesn’t even consume human food.

Furthermore, Nezuko has never shown any signs of malnutrition, as she is always ready to help her brother with her overwhelming strength and deadly Blood Demon Art.

How can Nezuko resist blood and survive without it in Murderer of demons?

On Murderer of demons, human blood is a source to increase the strength and powers of demons, so they hunt and devour them. Demons are basically immortal and can survive without eating for over a millennium with ease.

However, they do need blood to accomplish powerful feats like rapid regeneration and maintaining their composure.

This scene is a very impressive moment for Nezuko but it hurts me for Sanemi because she must feel so guilty, like if this demon can resist her blood and can live without hurting anyone, why couldn’t her mother live like this too?

Nezuko can survive without a single drop of blood and even resists Sanemi Shinazugawa’s rarer Marechi Blood, impossible for a demon to do. The only time she shows her desire to devour a human is when she breaks her snout and transforms into her awakened form.

Although it was the blood that was driving her crazy, it wasn’t that she wanted to eat humans. Nezuko forgot the existence of her brother by her side in her frenzied state, as she had at the beginning of the story. This shows the instincts of a demon and his bloodlust, but she doesn’t bow down to them.

Unlike other demons in Murderer of demonsNezuko relies on sleep, which restores her lost energy. However, her sleep intervals are abnormal, as it can take up to a week or a month before she wakes up.

In the first part of the anime, when Tanjiro Kamado received his swordsmanship training from Urokodaki Sakonji, his sister slept for over six months.

Also, while Nezuko was sleeping, Sakonji made a hypnotic suggestion to make him think that all humans are his family. That is why he sees a fragment of her family in each person, as they remind the protagonist of her loved ones. As a result, she can avoid harming humans and sees demons as enemies.

In addition, he also has a bamboo muzzle on his mouth given to him by Water Hashira Giyu Tomioka to hide his fangs and help control his bloodlust. All of these factors combined help Nezuko stay away from human blood and flesh.
