"How was your time as a demon slayer?" Asked the handsome man in front of me.
"It was fun overall, but there wasn't anyone that was stronger than me." I responded.
By now, I had already informed Muzan that I could speak once again, and so he just talked with me normally, as if I had been able to speak in the first place.
"So what do you want to do now?" He asked, actually curious about his "son".
"Can I just take some demons and start waging a war agains the Demon Slayers?"
"Sure, take 3 of the upper moons and any demons you find along the way, after all, you should be stronger than all of them by now, right?"
"In a one on one? Then yes, but I would probably lose if I fought all of the upper moon at a single moment."
"Yeah yeah, now, which 3 do you want to fight with?"
"Kokushibo, Hantengu, and Douma."
"Hmm... an interesting lineup, but I'll grant your wish."
"Thank you so much, Father!"
He smiled at me as he heard me call him father, before turning around and getting back to his studies, not forgetting to call the three that I had requested to come here.
Seeing them appear in front of me, they already knew their mission from Muzan's orders and so they just followed me.
Moving outside of the house, as to not disturb Muzan, I stopped and thought for a second about where the best place to attack was.
Thinking that the Swordsmith Village was the best target, I immediately phased away from my previous position, and the rest of the upper moons followed.
Arriving and seeing the hustle and bustle of the blacksmiths making those nichirin katanas, I calmly stroked my own nichirin chokuto.
"Just destroy everything, leave none alive."
Nodding, they all disappeared, and a moment later, screams started ringing out in the air along with the sounds of swords clashing.
Thinking that it might be a good time to try a few of my other forms, I stood there on the roof of the house with my chokuto pressed against my chest.
'Star Breathing - Second Form: Descent of a Red Supergiant.'
Immediately, the sky around the village turned red as a red entity in the sky started slowly falling down on the surrounding area.
I had already signaled to the 3 others, so they had already put up their defenses skill, a stark contrast to the swordsmiths who were just standing there staring blankly at the face of their own death.
Once the red entity touched the ground, everything in the surrounding area was incinerated and a smoking crater was left behind, with only the 4 of us being the only living things left alive in it.
"Where to next, boss?"
Hearing the sudden shift in their attitude, I smiled inwardly.
After all, with that show of power fresh in their minds, they were now much more respectful to me.
If before, they hadn't spoken to me, they were now asking my explicitly for instructions and orders.
Honestly, it felt kind of good, this feeling of power over other beings, but I suppressed this feeling and moved on to my next target.
"Let's head to Tokyo next, I think that it's about time we make some big moves now with their entire supply chain now destroyed."
Hearing this, once again, we all phased away as we headed towards Tokyo.
...
Well, let's just say that Tokyo fell just as fast as the Swordsmith Village.
By now, we must have attracted the attention of the Demon Slayers as we had literally destroyed a whole city after all.
Just sitting down, I motioned for the others to do the same as we just waited in the smoking ruined metal jungle that once was a bustling, happy city.
Grabbing the arm of a woman that I had killed, I started slowly gnawing on it to pass the time.
Finally, looking into the horizon, we saw the image of hundreds of figures backdropped by the orange setting sun.
"It seems like they brought the entirety of the corps."
"Of course, if they hadn't, I would have felt a little insulted, wouldn't you guys have been insulted too?" I asked.
Thinking about it for a second, they all nodded their heads in agreement before we all stood up simultaneously to prepare for battle.
Then, not giving them to draw their swords, we unexpectedly just rushed into the midst of them, tearing our claws through anything that felt soft.
Not reacting due to the shock at first, after a few seconds, most of the experienced Demon Slayers pulled out their swords and started making futile attacks against the four of us.
Just slicing through the cannon fodder like a knife through warm butter, I pushed forward farther and farther until I reached my first Hashira.
'Star Breathing - First Form: Birth of a New Star."
Immediately beheading the Wind Hashira, I didn't even give him time to see my face, so he was never able to take his revenge on me for humiliating him so much.
Sensing his younger flying at me with a sword and gun aimed at my head, I just sliced with my chokuto and he met the same fate as his brother.
Continuing through the sea of Demon Slayers, I finally decided to try using my other arm, as I had never used it before in battle.
Switching, I sped through even faster as my tired left hand was given some time to rest whilst my right hand, full of energy, was allowed to let loose on the poor cannon fodder.
Finally, I arrived at the line of Hashira, as they all kept their eyes on me, afraid to blink in case I just suddenly killed one of them.
"Die!"
Hearing a stupid shout from behind me, I just swung my unsheathed Chokuto at them, but then realized that they had actually been able to withstand my block.
Turning around, I saw a familiar Demon Slayer dressed in a green striped kimono with hanafuka earrings.
"Well, well, well, if it isn't Kamado Tanjiro."
