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

Inside a vast chamber deep within Muzan's fortress, a sinister atmosphere filled the air. Dark mist curled around the floor, and shadows shifted like living creatures. One by one, the Upper Moons appeared—each summoned by Muzan himself.

Kokushibo stood tall, his six eyes glowing faintly. Douma entered with his usual unsettling smile, spinning his fan lazily. Akaza knelt silently, still shaken from his encounter with Saitama.

Gyokko squirmed into the room like a grotesque work of cursed pottery, and Hantengu trembled, already paranoid.

Once they were all gathered, Muzan's presence swept over them like a crushing weight. His eyes glowed a deadly crimson. "I have summoned you all for one reason."

The demons exchanged quick glances—what could possibly warrant such an urgent meeting?

Muzan's voice was cold. "There is a human… a bald human… whose strength defies all logic."

Douma's smile widened. "A bald human? My, my, that's unusual. Is he some legendary monk or—"

"No." Muzan's glare silenced him. "He is no monk. He is simply… a man who claims to be a hero for fun."

Kokushibo's brows twitched slightly, the statement so absurd it barely registered as a threat. "Surely you're not concerned about a single human, Lord Muzan."

Akaza clenched his fists. "Do not underestimate him! I fought him briefly, and his punch—just a casual punch—was powerful enough to crack the earth and send me flying across the forest."

The room grew silent. Even Kokushibo was forced to reconsider.

"He did that to you?" Douma's grin flickered, his fan stopping mid-spin. "Oh, now I'm interested."

Muzan's voice grew sharper. "This 'Saitama'… if he interferes with my plans again, you will eliminate him—together if necessary. I will not tolerate some hairless clown standing in my way."

Hantengu whimpered, his fear taking over. "B-b-bald humans are scary!"

Gyokko sneered. "Bald or not, we are the Upper Moons! No human should stand a chance."

Muzan's gaze swept over them. "That is what I thought too. And yet here we are."

The weight of those words settled heavily upon them. For centuries, Muzan had shown nothing but disdain for humans. But now, for the first time, there was a flicker of unease in his voice.

"Find out everything about him," Muzan commanded. "His origin, his weaknesses—if he has any."

As the meeting ended, Akaza's mind replayed that ridiculous, blank expression Saitama wore. That deadpan face haunted him more than any blade ever could.

Meanwhile, at the Butterfly Mansion…

Saitama sneezed. "Someone talking about me?"

"Sensei, are you okay?" Tanjiro asked, handing him a bowl of rice.

"Yeah. Just felt a little evil aura in the air or something." Saitama shrugged, already thinking about what's for dinner.
