How did Muzan Become a Demon?
Muzan Kibutsuji, the main antagonist of the anime and manga series Demon Slayer: Kimetsu no Yaiba, was born a human. However, he became a demon after being injected with a serum made from the Blue Spider Lily flower. The serum gave him immortality and superhuman strength, but it also made him susceptible to sunlight and water.
Muzan was born in the Heian period of Japan, around 1,000 years before the events of the series. He was a sickly child, and he was constantly dying. His parents took him to see many doctors, but none of them could cure him.
One day, Muzan's parents heard about a doctor who lived in a remote village. The doctor was said to be able to cure any illness. Muzan's parents took him to see the doctor, and the doctor agreed to treat him.
The doctor gave him a serum that he had made from the Blue Spider Lily flower. The Blue Spider Lily flower is a rare and poisonous flower, but it is also said to have the power to grant immortality.
The serum worked, and Muzan was cured of his illness. However, the serum also had a side effect. It turned Muzan into a demon.
He was furious when he found out that he had become a demon. He blamed the doctor for turning him into a monster, and he killed the doctor.
Muzan then set out to find a way to cure himself of his demonhood. He traveled all over the world, but he could not find a cure.
Eventually, he gave up hope of finding a cure. He decided to embrace his demonhood, and he vowed to rule the world.
Muzan is a powerful and ruthless demon. He is the creator of all other demons, and he is the main antagonist of the Demon Slayer series.
