Mori smiled confidently as he leaned back.

"I guess I could be a Hashira," he mused, tilting his head slightly. "BUT I don't want to be responsible for a specific territory. I don't wanna manage a certain region or deal with reports and patrols. I just want to travel wherever I want and take down demons as I see fit."

The Hashira immediately turned their sharp glares toward him again, clearly displeased with his nonchalant attitude. However, before they could voice their objections, Kagaya Ubuyashiki chuckled softly and nodded in understanding.

"That is fine," Kagaya agreed with his ever-calm demeanor. "Instead of assigning you a fixed region, how about we implement a quota system? Every month, you must slay at least ten demons. As long as you fulfill that requirement, you will retain your status as a Hashira."

Mori thought about it for a moment before shrugging.

"Yeah, I'm perfectly fine with that," he said, grinning. "But it'll have to wait until my weapon attachments arrive. Without them, I can's exactly kill demons yet." He scratched the back of his head sheepishly. "Until then, I'll probably just travel around and kill demons whenever I come across any."

Just as he was about to leave it at that, a sudden thought struck him. He slowly turned his gaze toward the other Hashira, and a mischievous smile stretched across his face. His eyes gleamed with a dangerous light as he let out a quiet, raspy giggle.

The group standing beside him involuntarily shivered.

"I've been thinking… the current Demon Slayers are too weak," Mori declared, his tone carrying a hint of amusement. "How about I train them a bit? I could teach them some martial arts that would significantly improve their strength. It'll make them much more effective in battle."

Kagaya raised an eyebrow, intrigued by the proposal. After a brief moment of contemplation, he nodded.

"That sounds like a wonderful idea," he said gently. "If your training can improve their overall combat abilities, then I fully support it."

Mori's grin widened even further as he clasped his hands together in excitement.

"Good, good," he murmured. He then turned back to the group of Hashira, who were still unsure whether this was a good or bad thing.

"All of you better be at the Butterfly Mansion within five days," he suddenly announced. Reaching into seemingly nowhere, he pulled out a green military cap and placed it on his head. His smirk deepened as he adjusted it, then pointed at them dramatically.

"I'll whip you all into shape, you maggots!" he bellowed, laughing heartily as he marched away.

The Hashira stood frozen in place, their faces stunned. They had met all sorts of people, but Mori was by far the most unpredictable and bizarre individual they had ever encountered.

With that, the annual Hashira meeting came to an unexpected and strange conclusion.

5 Days Later~

The Butterfly Mansion's training ground was filled with the Hashiras, all standing in a single line, wearing identical training gi. Despite their strength and pride, there was an undeniable tension in the air. Even Kanae, watching from the side with a soft smile, could feel the unease radiating from them.

Then, Mori made his grand entrance.

Marching out of the mansion, he was now fully dressed in a green camouflage military outfit, complete with sunglasses and dog tags. He looked nothing like a Demon Slayer and everything like a drill sergeant.

"Alright, you sleazebags!" Mori bellowed, his voice carrying across the courtyard. "Today is the day you officially start your training! Forget who you are! Forget that you're Hashira! You are no different from a Mizunoto recruit! You are cannon fodder! Get rid of the mindset that you're elite warriors!"

Circling the group, he scrutinized their stances, his expression filled with disdain. He then summoned his staff, Yeoui, from his inventory and began using it to correct their postures with small "taps"—though, in reality, each tap was strong enough to leave noticeable bruises.

By the time he was done adjusting them, their legs were shaking, and a few had large comical lumps on their heads.

"Since you are training under me, you will follow my orders regardless of what you want or think! Is that clear?!?!" Mori shouted, slamming his staff against the ground.

The group stiffened. A cold chill ran down their spines. Even Gyomei, who was usually as steady as a mountain, felt a hint of unease.

"Scary…" they all thought simultaneously.

"First order of business—HAIR!" Mori suddenly declared, pulling out a pair of scissors from his pocket. "All of you will have your hair cut short! No exceptions!"

Sanemi and Tengen immediately protested, stepping forward to argue.

"Like hell I'm getting my hair cut!" Sanemi snapped.

"This is not flamboyant at all!" Tengen complained.

Their protests were short-lived, however, as Mori swiftly knocked them both on the head with his stone staff. The impact was so sudden and powerful that they immediately fell silent.

With a satisfied grin, Mori proceeded to give them all buzz cuts, one by one. Gyomei and Rengoku, who already had relatively short hair, didn't mind, but the others were left utterly devastated.

Once their hair was taken care of, Mori moved on to actual training. He began demonstrating Wolgwang Swordsmanship and Kyokushin Karate, breaking down the techniques for them. Afterward, he let them practice—while ensuring that every mistake was met with swift and painful correction via Yeoui.

Day after day, they trained rigorously. Every session ended with them fighting Mori, testing their limits against him.

This brutal regimen continued for an entire month. By the time they had fully adapted, they had learned how to incorporate martial arts into their Breathing Styles, drastically improving their overall combat effectiveness.

One Month Later~

The group of Hashira stood in a perfectly straight line, facing Mori. Their expressions were exhausted but firm, their bodies significantly stronger than before.

Mori placed his hands on his hips and nodded approvingly.

"You maggots have done well," he said, his voice filled with exaggerated pride. "From now on, you have officially completed my training. You've all made me so proud."

He dramatically wiped his nonexistent tears, sniffling for added effect.

The Hashira shivered.

Without hesitation, they all turned and walked away as fast as possible, not wanting to spend another second under Mori's command.

Kanae chuckled from the sidelines as she watched them flee.

With his training complete, Mori began making preparations for his next journey. He had more important matters to attend to—namely, his upcoming world travel.

After bidding farewell to his sisters, he left the Butterfly Mansion and set off on his journey. He traveled for two days before stopping in a village, where he paid for an inn and settled into his room.

As he relaxed, he opened his system menu.

"System, if I leave this world, will time continue moving here?" he asked curiously.

A blue dialogue box appeared in front of him, displaying the answer.

"Yes and no There is no temporal anchor. Every time you travel to a different world, the time ratio changes from 1:1 to 100:1. This means that for every 100 days spent in another world, only 1 day will pass in your current world."

Mori exhaled in relief.

"Good. That means I can return after just a single day here," he muttered to himself.

Then, his lips curled into a smirk.

"Now that I know how this works… I know just the world to go to," he said, his eyes gleaming with excitement.
