Nezuko and Muzan are names that often come up together in fan discussions. While the Hashira are the strongest Demon Slayers in the series, Muzan showed more fear toward Nezuko than he ever did toward them. But why? Well, there was something much deeper that troubled him.

In the world of Demon Slayer, strength alone doesn’t decide who is feared. Muzan never really panicked when facing powerful Hashira. He was confident in his own power and the Demons he created. But Nezuko was different. She was the one thing Muzan couldn’t fully understand or control. That made her a serious threat.

The Main Reason Why Muzan Feared Nezuko

One of the biggest reasons Muzan feared Nezuko was that she could walk in the sun. For Demons, sunlight is like poison. Even the strongest Upper Moons would turn to ash if touched by it. Muzan had spent hundreds of years trying to overcome this weakness. He had tried every method, but nothing worked.

When Nezuko became the first Demon to survive sunlight, Muzan saw her as the key to his dream of perfection. But he also realized she was a major risk. If someone else learned how she conquered the sun, his whole plan could fall apart, and even the Demons could turn against him. Thus, he didn’t want her power to spread.

Nezuko Was Unpredictable

Most Demons followed Muzan’s orders or lived to serve his purpose. Nezuko was different. She was a Demon, but she didn’t act like one. She never ate humans — in fact, she fought to protect them. Her willpower was so strong that even Muzan couldn’t control her like the others.

This scared Muzan more than raw strength. He had full control over the Demons he created, but Nezuko broke that rule. She had feelings, made choices, and held onto her humanity. That made her impossible to predict. A Demon that couldn't be controlled was something Muzan had never faced before.

The Hashira Were Powerful, But Expected

Muzan didn’t fear the Hashira as much because he knew how they worked. They trained, got stronger, and followed rules. He had seen Demon Slayers like them for centuries and killed countless of them over the years.

Nezuko didn’t fit into any system. She broke all the rules. She didn’t need a sword or breathing techniques to fight Demons. She was growing stronger every day without anyone fully understanding how. To Muzan, that was terrifying. A new kind of threat with unknown limits was far more dangerous than a known enemy.

Final Verdict: Muzan Feared Nezuko's Resolve

Nezuko survives the sun and Muzan is looking for Nezuko to absorb her

Nezuko was a symbol of everything Muzan couldn’t control or predict. While the Hashira were strong warriors, Nezuko had something even more powerful. It was her rebellious nature that broke the Demon code, which came as the biggest surprise for the King of Demons.

In the end, it wasn’t her power alone that scared him. It was the fact that she survived, resisted, and grew stronger without ever giving in. Nezuko was living proof that Muzan could be defeated in ways he never imagined.
