Mystic Demon Slayer

{3 Days latter}

Zenitsu walked Inside a forest as he looked bored, in those 3 days he finished another mission and now he is just walking around until he gets another one

'I Hope I get a powerful enemy, I may be strong with all the training and techniques I created but nothing yet was able to force me to exert my power and use my most powerful techniques and my eyes are just too overkill to use in any scenario, if this keeps on I may go hunting for a Hashira to fight at least that would be fun'

Suddenly his head snapped towards the south as he sped towards it in insane speed, getting closer to his destination he started slowing down until he got our of the grand expanse of trees as a mansion appeared in from of him

in from of the mansion a corpse lay there as dead as it could be, looking to his right a small box appeared in his field of vision, looking at it he couldn't help but feel weird

'A Demon in a box? Weird…. Should I directly cut the box and kill it? I am too lazy to check the box out…meeh ill just destroy it'

Raising his hand a sword appeared in it as it started shining with lightning, without hesitation he slashed down with all his power as the sound of thunder spread everywhere, Just as the sword was about to hit the box it stopped as Zenitsu looked weirdly at the box

'It didn't react? Not does it have the scent of blood on it, and even when I was about to kill it the demon didn't react or show any intent harming me… weird'

"I Have never seen something this interesting..."

Holding the box Zenitsu walked towards the forest as the shades of the trees caused the place to become devoid of sunlight so a demon can walk there

Opening the box slowly Zenitsu looked blankly at what was inside of it as the demon walked out, a small girl with black hair that fades into orange near the end and bright pink eyes as she carries a piece of bamboo in her mouth bound by a red tie

Looking at zenitsu she tilted her head to the side as if confused she just dropped back into the box as if tired, Looking at her Zenitsu couldn't help but wonder

'How can something this cute be a demon, well she doesn't seem to be dangerous as I sensed no will from her to harm me… weird, this box she is in appears to be made so someone can carry it and for it to walk in daylight it must be a human'

Looking back towards the house he could sense some demons inside of it, and also some humans 4 of them or so, focusing more on it one of them seemed to possess a familiar aura to zenitsu

'It must be someone I met before, but I can't remember from where...'

Looking at the box behind him he closed the small box as he walked towards the house slowly

'I am not interested in those weak demons, but this girl is interesting and I want whoever carried her here to be alive for me to ask what is happening, so I gotta kill the demons inside…. I never tried doing this before to a house but whatever...'

'This whole house is the demon's territory, its the strongest demon I have ever met till now...its a pity I won't fight it but it's easier'

Raising his head to the sky he looked at the sun blazing in the sky, slowly looking back to the house his eyes became sky blue with rainbow color around the pupil

Holding his sword he looked at the house and activated 'awareness' looking at the multiple lines around him Zenitsu chose one that won't touch any of the humans inside

Waving his sword he cut along the line, a fraction of a second later the top of the house slid down and crashed to the floor next to the house causing everything inside to be exposed to the sun

Soon after screams came from inside the house but died soon, noticing some places still not exposed to the sun become of the fact that the mansion was a 2 story one

He just waved his sword a couple more times destroying their top as to expose them, That caused more screams to appear that ceased soon after, with that Zenitsu's eyes reverted to their golden color as shock head

'Too boring… never gonna use those eyes again unless I am in danger, things are too easy using them'

With that, he went back and sat next to the box as he waited for the humans inside to come out, and as if they heard him they came out

2 Kids with 2 guys that appeared demon hunters, well...those demon hunters doesn't appear to be together as one of them, more precisely the one with a bore mask on his face ran towards the box next to him waving his sword, While the other one ran behind him as he tackled him as they started fighting, it ended fast with one getting a headbutt that probably caused some sort of concussion

Seeing it end he looked at the guy with green and black haori and called for him

"so are you the guy walking around with the demon?"

'No wonder I felt the presence inside familiar so its the guy from the final selection...'

Looking at Zenitsu next to the box Tanjiro couldn't help but worry but with his sense of smell he could smell she is not hurt so he calmed down and looked at Zenitsu before recognizing him

"You are the guy that ran into me in the final selection!"

"Yes that's me but can you tell me about this demon I am quite curious about it"

Hesitation for a bit Tanjiro decided to tell him as seeing what happened to the house and no other demon slayer here it was probably this guy, and seeing that he didn't harm Nezuko he is probably friendly

"Uhh, it's like this…."
