Anime Demon Slayer: Kimetsu no Yaiba

Why is Muzan looking for the Blue Spider Lily in Demon Slayer?

Muzan Kibutsuji made his first appearance in Season 1, Episode 7 of the anime series Demon Slayer: Kimetsu no Yaiba.

He’s the main antagonist of the series – the Demon King – and is said the be the first demon ever to be created.

Muzan is an intriguing character. And not just because of his uncanny resemblance to the King of Pop, Michael Jackson. Muzan is a formidable foe to the demon slayers.

He is a cold-blooded killer, either offing humans, or better yet – turning them into demons.

But is there a deeper purpose to him creating an army of demons for himself? Could it have something to do with his quest for the blue spider lily?

SPOILERS AHEAD! This page contains spoilers from Demon Slayer.

Why Is Muzan looking For The Blue Spider Lily?

Muzan is searching for the blue spider lily to gain immunity against the sun so he can perfect immortality.

In chapter 127 of the manga, Muzan’s backstory reveals that he needs the blue spider lily to conquer his weakness, or a demon who could resist the sun so he can absorb their power.

In the Heian Period, Muzan was a mere mortal before he was turned into a demon. Muzan had been told he would die at the age of 20 due to an unknown disease.

A kind, munificent doctor takes him in and treats him with an experimental medication derived from the mysterious blue spider lily.

But the drug, being a prototype, is slow to show its effects. Angered by his declining condition, he kills the doctor who had saved his life.

It is only after the doctor is slain that Muzan realizes that the medicine had been working. But since he hadn’t completed the entire dosage, Muzan’s treatment is left incomplete.

He realizes he is helpless and vulnerable in sunlight, and merely stepping out in the afternoon could disintegrate his body.

The doctor had been the only person who knew the whereabouts of the blue spider lily. Muzan makes it his life’s aim to look for it so he can gain total immortality and immunity against the sun.

Does Muzan Find The Blue Spider Lily?

Muzan never finds the blue spider lily. He is left fearing the sun and fearing death, the blue spider lily forever out of his grasp.

The flower only blooms during the daylight hours, 2-3 days in a year. With Muzan only able to roam the earth in the dark of night, he is unable to ever find it.

This only goes to show what a tragedy Muzan’s character is. Had he not given in to rage and desperation, he would have competed the treatment the doctor offered him and become the ultimate demon.

Subsequently, if Muzan were perhaps less impulsive and more patient, he could have devised a way for a human to get the blue spider lily for him, since demons cannot bear being under broad sunlight.

What Does A Blue Spider Lily Do? What Are Its Properties?

The blue spider lily is rare type of flower in the Demon Slayer universe that has regenerative properties. It is said to have the capability of creating demons.

It gives rise to the Original Demon – Muzan – and if perhaps administered to its full dosage, can help spawn demons with the perfect immortal body, resistant to the sun.

100 years after Muzan dies, Aoba Hashibira, a botanist-researcher, locates the blue spider lilies but due to a mistake during an experiment, they all wither and die.

As a consequence, the demon race is abrogated. So, the actual properties of the blue spider lily will always remain a mystery.
