Demon Slayer spinoff scenario one: Humanity becomes Muzan’s prey

In this scenario, Muzan becomes an unstoppable predator, with humanity as his helpless prey. His new immunity to sunlight means there’s no escape, day or night. Muzan, already a selfish and cruel being, would act without limits, feeding on humans whenever he pleased. People could do nothing but hope they aren’t his next target. The world would turn into his personal playground of fear.

Even the strongest weapons, like nuclear bombs, wouldn’t be enough to stop him. Muzan’s ability to change his body at will would let him escape or hide before anyone could attack him. And if humans did try something as extreme as nuclear weapons, it would cause massive destruction, hurting humanity more than him.

In this version of events, Muzan would rule the world as a predator with no equal. Fear and chaos would dominate, and humanity would struggle just to survive. It’s a nightmare vision of a world where no one is safe.


Demon Slayer spinoff scenario two: Muzan's endless fear of death

Muzan has always been obsessed with staying alive. His whole life, both as a human and a demon, was about avoiding death at any cost. In this version of the story, even though he gains ultimate power, he doesn’t feel peace. Instead, his paranoia would grow worse.

Now free from the sun’s threat, Muzan might start worrying about other ways he could be destroyed. He could spend hundreds of years searching for anything that might harm him. His endless fear of death would turn into a new obsession, and he would likely attack anything he thought could be a danger.

This scenario shows that even with his victory, Muzan wouldn’t be truly happy. His fear would keep him trapped in a life of constant worry. It’s a tragic idea, where his greatest success only makes him more miserable.


Demon Slayer spinoff scenario three: Muzan curse of emptiness

What if Muzan achieves his goal and realizes it’s not what he wanted after all? This scenario explores what happens when someone like him gets everything they’ve ever wished for but still feels empty inside.

At first, Muzan might celebrate his immortality, enjoying his new freedom from the sun. But over time, he would likely realize that he has nothing left to live for. He spent centuries focused on survival, but now that he has no enemies or weaknesses, his life feels meaningless.

In his frustration and sadness, Muzan might lash out, destroying humans and demons alike. Not because he needs to survive, but because he’s angry at how empty his existence has become. His immortality becomes a curse, leaving him stuck in a hollow, miserable life.

A spinoff where Muzan becomes immune to sunlight would be an exciting twist to the Demon Slayer story. Each scenario shows a darker side of his personality and the outcomes of his ultimate victory.

Whether he turns into an unstoppable predator, a paranoid loner, or an empty destroyer, this story would show how power and immortality can cause more pain than happiness. It would be a gripping addition to the Demon Slayer world and a strong reminder of the dangers of greed and selfish ambition.
