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

The sun was high above the Butterfly Mansion, and Tanjiro, Zenitsu, and Inosuke stood nervously in the courtyard. The Hashira had told them the "Legendary Hero from Another World" would be personally training them today.

Saitama stood before them, looking absolutely bored, scratching his bald head with a chopstick. He held a steaming bowl of ramen in his other hand.

"Alright," Saitama said lazily. "Training starts now."

"Eh? But you're still eating!" Zenitsu complained.

"This is training." Saitama slurped his noodles, then pointed down the hill. "See that noodle shop at the bottom? You're gonna run there, order me another bowl, and run back before this one gets cold."

"WHAT KIND OF TRAINING IS THAT!?" Zenitsu screamed.

Inosuke immediately cracked his knuckles. "I like it! Speed and violence! This is my kind of workout!"

Tanjiro tilted his head. "But… sensei, what's the point of this?"

Saitama looked absolutely serious for once. "The point is — if you're too slow, my lunch gets ruined."

Everyone fell over.

"Alright, ready? GO!" Saitama yelled suddenly, shocking all three of them into sprinting down the hill.

Zenitsu activated Thunder Breathing right away, leaving sparks in his path. Inosuke ran on all fours like a wild beast, while Tanjiro combined Water Breathing footwork with pure desperation.

Saitama sat back down, calmly sipping his broth. He didn't even watch.

At the ramen shop, chaos erupted.

"Three bowls of extra-spicy tonkotsu! Hurry, it's for the bald monster guy!" Zenitsu shouted, slamming his hand on the counter.

"Eh?! You mean that bald guy?!" the old ramen chef panicked. "The one who ate 25 bowls and said he was just warming up?!"

"LESS TALKING MORE NOODLES!" Inosuke roared.

The chef's hands blurred as he made the fastest ramen of his life.

On the way back up the hill, disaster struck. A wild lower-rank demon emerged from the forest, drawn by the scent of human sweat and fear.

"Oh no!" Tanjiro drew his sword.

"Forget it! Just run!" Zenitsu wailed, sprinting past the demon at lightning speed, balancing the bowls on his head.

"I'LL KILL YOU AND DELIVER THE NOODLES!" Inosuke charged the demon directly.

The demon, utterly confused, was punched in the face by a noodle bowl. Ramen splattered everywhere.

"NOOOO! THE RAMEN!" Tanjiro cried out.

"Forget the demon! Save the food!" Zenitsu shrieked.

From the top of the hill, Saitama casually appeared behind the demon. One gentle tap later, the demon disintegrated into dust, leaving only a faint, confused scream.

"Why… ramen…?"

The three trainees collapsed at Saitama's feet, holding up two slightly cracked bowls and one bowl full of grass, dirt, and demon goo.

"Two out of three. Not bad for your first day," Saitama said, giving them a rare thumbs-up.

"That… that wasn't training…" Zenitsu sobbed. "That was delivery service…"

"Wrong." Saitama leaned closer. "Training means doing the job no matter what obstacles get in your way. Hungry demons? Steep hills? Lightning-crybaby teammates? Doesn't matter. You deliver. Every time."

The three of them stared at him in awe. Somehow… it made sense. In a bizarre, Saitama kind of way.

"Tomorrow, we're going for five bowls," Saitama said, slurping what was left of his meal.

And thus began the strangest training arc in Demon Slayer history — The Ramen Sprint Arc.
