Demon Slayer: How did Muzan become a demon? Explained

Muzan Kibutsuji, the main antagonist of the popular anime series Demon Slayer: Kimetsu no Yaiba, is a powerful and enigmatic figure shrouded in mystery. His origins and transformation into the progenitor of all demons are a subject of fascination and intrigue among fans.

Muzan's Life Before Becoming a Demon

Muzan was born into a wealthy family during the Heian period of Japanese history. He was a sickly child, often bedridden and unable to enjoy the same activities as his peers. Despite his frail health, Muzan was known for his sharp intellect and a thirst for knowledge.

One day, while exploring a temple with his family, Muzan stumbled upon a hidden room containing an ancient medical text. The text described a powerful blue flower that was rumored to possess the ability to cure any ailment. Driven by his desire for a normal life, Muzan embarked on a quest to find the blue flower.

Encounter with Kuchiki Tenzen

After years of searching, Muzan finally located the blue flower. However, as he was about to consume it, he was confronted by Kuchiki Tenzen, a demon slayer who had been tracking him. Tenzen warned Muzan that the blue flower was not a cure-all, but rather a gateway to a demonic existence.

Muzan, desperate to rid himself of his sickly condition, ignored Tenzen's warnings and consumed the blue flower. The flower's effects were immediate and transformative. Muzan's body healed, his senses heightened, and he gained immense strength and regenerative abilities. However, the transformation came at a terrible price. Muzan was no longer human; he had become a demon.

The Birth of a Demon Progenitor

As the first demon, Muzan possessed the ability to create other demons by sharing his blood with humans. He began to experiment with his newfound power, turning individuals into demons to serve as his loyal followers.

Muzan's hunger for power grew insatiable. He sought to create an army of demons that would rule the world, and he would stop at nothing to achieve his goal.

The Demon Slayer Corps' Response

The Demon Slayer Corps, an organization dedicated to protecting humanity from demons, became aware of Muzan's existence and his growing threat. They vowed to eliminate Muzan and his demon followers, and a long and bloody war ensued.

Muzan's Legacy

Muzan's transformation into a demon and his subsequent reign of terror remain a dark chapter in the history of the Demon Slayer universe. His insatiable hunger for power and his willingness to sacrifice others for his own gain make him a truly formidable and terrifying adversary.

Even after his defeat at the hands of Tanjiro Kamado and his allies, Muzan's legacy continues to haunt the world of Demon Slayer. His descendants, the Upper Moon demons, continue to pose a threat to humanity, and the scars of Muzan's reign are still felt by those who survived his demonic reign.
