The One Punch Man (a.k.a Saitama) in Demon Slayer

The wreckage of the ramen shop crackled softly, faint embers flickering in the morning breeze. The Hashira stood on edge, blades drawn, eyes locked on Kibutsuji Muzan.

Yet… nothing happened.

Muzan's crimson eyes swept over each of them, but his focus landed — and stayed — on Saitama. The caped man stood there casually, hands tucked into his sleeves, face blank like always. To any normal person, Saitama looked harmless — like some forgettable extra who stumbled into the wrong story.

But Muzan wasn't normal.

And what he felt when he looked at Saitama was terrifying.

It wasn't bloodlust.

It wasn't malice.

It was… emptiness.

An overwhelming, suffocating void where an aura should be. No fear. No intent to kill. Not even the excitement of battle. Just absolute nothingness — the calm presence of someone who could destroy everything without even trying.

"Who… are you?" Muzan asked, voice quieter than usual.

Saitama tilted his head.

"Me? Just a guy who wanted ramen."

The Hashira all exchanged confused glances. Was this some kind of joke? But Muzan's face showed no humor — only suspicion, maybe even a hint of fear. Something was off, and they could all feel it.

Muzan's fingers twitched at his side, blood techniques ready to activate at any moment, but something stopped him. Instinct. For the first time in centuries, Muzan felt something primal — like standing at the edge of a cliff, knowing one wrong step would mean falling into a void with no bottom.

He couldn't read Saitama. And that terrified him.

"I have more important things to do," Muzan said, voice returning to his usual smooth arrogance. "This… was just a waste of my time."

He turned his back to them, cape billowing slightly as he walked away, steps eerily calm.

"Running away already?" Sanemi barked. "Afraid to fight?"

Muzan didn't even glance back.

"Your time will come," he said, "when I have no further use for you."

The Hashira were furious — ready to chase him down — but Saitama raised a hand.

"Let him go," Saitama said, yawning. "If he doesn't want to fight, I'm not interested either."

The Hashira nearly fainted from frustration.

"What is wrong with you?! That's Kibutsuji Muzan — the king of demons!" Rengoku roared. "We can't just let him—"

"He's scared," Saitama said simply.

That shut everyone up.

"Scared?" Giyuu frowned.

"Yeah," Saitama rubbed his bald head. "You saw how tense he was? People only act like that when they feel something stronger than themselves. Kinda like when I met that mosquito in my world."

"…What?" Shinobu whispered.

"Anyway, I'm still hungry," Saitama said. "Any other ramen shops around?"

The Hashira collapsed to the ground, completely exhausted mentally and physically.

But inside their hearts, a strange new hope flickered — because Muzan, the creature they feared most, had just walked away from a fight.

All because of this bald man in a cape.
