Mission

"Your welcome... Zenitsu..."

I sheathed my swords, as I watched his Haori float away in the wind.

Ya'know, I haven't actually dealt with a situation like this. Zenitsu was a good guy in the original timeline of Demon slayer, the one who was always scared but still fought with everything he had.

Micheal and Jason? Those were real fucking monsters that didn't deserve any sympathy or pity. But Zenitus? This guy... this guy was broken long before I ever crossed paths with him.

I looked down at where Zenitsu's ashes had settled, the sunlight still flickering through the leaves. He was gone, and with him, another piece of whatever was left of this world. Muzan really did a number on him, twisted him into something unrecognizable.

...Muzan.

He most likely got to Tanjiro, Inosuke, even the remaining Hashira... they were all probably demons now.

But there was no time to dwell on that. I still had a mission to complete, and Zenitsu's death was just a step in that direction. Muzan's probably knows someone killed Zenitsu thanks to all that weird Muzan blood mumbo jumbo, so I should get out of here.

[EMERGENCY!]

[Anomaly corruption level has exceeded hunter August Ramos's level!]

[Assigning emergency hunt:]

[Current hunt: Muzan Kibutsuji?]

[General info: Muzan has almost achieved his goal of conquering the sun, but in the process came in contact with an anomaly. With this added power, the final battle between Muzan and the demon slayer corps ended in his victory, this world of Demon slayer is spiraling to the point of no return.]

[Goal: Hunt down the Anomaly Muzan Kibutsuji to save this world.]

[Disclaimer: By taking on this hunt, you will be given the ability to obtain presets of existing characters/people, aiding you in your hunt for Muzan Kibutsuji.]

[Disclaimer: You will be able to leave this universe once you hunt down Muzan Kibutsuji.]

"Damn, this a little worse then I thought."

Ok so just a light end of the world situation thrown at me, that's not to bad right?

"...."

"Fuck this is bad."

I let out a long sigh, trying to shake off the weight of what I was up against. Muzan's corruption had turned this world into a ticking time bomb, and now it was up to me to defuse it.

Great, just when I thought things couldn't get more screwed up.

I glanced at the remnants of Zenitsu, wishing I could have done more, maybe I should have tried saved him from whatever hell Muzan had unleashed.

No I can't be acting like this right now.

That was a luxury I didn't have. Not with Muzan out there, now more dangerous than ever.

Looking up again, the system screen was right in my face once again.

Can I check the Musashi preset please?

[Of course.]

[Preset: Miyamoto Musashi

-Description: The greatest swordsman of japan 400 years ago, revived into the modern era.

-Equipment: Twin Katanas]

Baki Musashi huh? A ancient swordsman in a world that's basically ancient Japan.

Hmm.

'Yeah this system is trying to push a theme'

[Do you wish to start the hunt?]

[Yes/No]

Man oh well,

Time to start this next hu....

...

...

...

"System, what are these presets doing to me?"

"That Kirei preset was fucking my mind up, is this going to continue happening every preset I equip?"

[Each preset comes with its own set of effects. The mental and physical alterations depend on the nature of the character and their abilities. The Kirei preset was particularly invasive due to Kotomine Kirei's own mentality and nature, so the level of corruption associated with it was much more stronger. Miyamoto Musashi's preset should have a different impact, though it's still important to be cautious.]

"Fantastic,"

"So, it's a roll of the dice with each preset. Just what I needed."

I do NOT want to go through that bullshit with the presets again, Kirei a cool character to watch but not to have fucking up your mind.

Especially with all the memory shit I've been experiencing.

I rubbed my temples, with all this information in front of me. If the Musashi preset was going to mess with my head like Kirei's did, I needed to be prepared for it. Baki Musashi was nowhere near as bad as Kirei, but I didn't have much of a choice. I had to take down Muzan before this world went completely off the rails.

[Do you wish to accept this hunt?]

[Yes/No]

"Fuck it, we ball. Yes!"

Scared? Yep!

Worried but the preset messing my mind up? Defiently!

Weirdly excited to cut down some demons? Hell yeah!

[The hunt for Muzan Kibutsuji has begun]

"Let's get this done, no more time to waste!"

<POV Change: Muzan Kibutsuji>

"Interesting...

Muzan stood in the shadows of a decaying temple, the air thick with the stench of rot and despair. His crimson eyes gleamed with a sinister satisfaction. The world was crumbling, and it was all going according to his plan.

The corruption he'd embraced had turned everything to chaos. The Demon Slayer Corps were shadows of their former selves, twisted into demons who served his will. The sun was nearly within his grasp, and the world was spiraling into darkness.

Yet he sensed a disturbance.

Someone had killed a former demon slayer under his control.

Zenitsu wasn't all that important to his plans, but he had been growing at a steady rate. GIve him a few more months and he could have become a valuable asset.

"Who could have killed Zenitsu then?"

A former fighter of the demon slayer corp?

Impossible.

He made sure to kill every single remaining one of them after his fight with the Hashira.

Muzan's eyes narrowed. Someone must be poking their nose where it didn't belong, and he wasn't going to let that continue.

Of course he wouldn't be the one going after this mystery person.

He had more important matters to attend.

Although, those two had proven themselves useful lately.

"Obani Iguro and Mitsuri Kanroji, the snake and love hashira's respectively"

"They've shown they are the most relentless of my new demons. Their abilities make them perfect for this kind of dirty work."

He remembered the transformation of Obani and Mitsuri after his fight with them, how they had been some of the strongest Hashira, and now they were formidable demons under his command. Iguro's snake-like movements and Kanroji's fiery strength made them ideal hunters.

They were entertaining to turn into his minions, and even more entertaining to watch them become loyal servants to himself

"Obani's unique skill set should be effective in tracking down our unwanted guest. And Mitsuri... her power and speed will ensure that nothing escapes her notice."

Muzan gestured with a flick of his hand, and the shadows around him seemed to pulse and writhe as they relayed his orders to his minions.

" I want this mystery person found and dealt with. They can become a threat to my plans, and I won't tolerate any more disruptions."

The shadows nodded in acknowledgment, vanishing into the dark.

Muzan's gaze turned back to the ruined temple, his thoughts swirling with anticipation and menace.

"Let's see how long this intruder lasts before Obani and Mitsuri close in on him."

He chuckled softly, the sound echoing eerily in the still air. The world was on the brink of destruction, and he was the one pulling the strings. The chaos was almost... poetic.

"Lord Muzan."

"Hmm? What is it Kanao?"

From his shadow, a girl slowly arised. One side of her looked strangely human, while the other half was full of pale blue skin paired with flowers growing out of her arm. A dead look was plastered on her face as she stared behind Muzan.

"We've found her."

A sick grin slowly formed on his faced as his eyes began to glow a pale red light.

"...You're finally in my sights."

The only one to escape his grasp at the end of his fight.

The one to stay hidden even after all of this time.

The girl who conquered the sun.
