Muichiro x Kotetsu (Demon Slayer Kimetsu no Yaiba)

Chapter One: The Doll and The Boy in the Mask (Someone's Dream)

After Mitsuri The Love Pillar Informed Tanjiro about a secret weapon that's somewhere hidden in the Swordsmith Village, the next day Tanjiro sets off thinking it be a fun Treasure hunt and so that he can learn more. Few minutes later Tanjiro watched in the forest of the Swordsmith Village, Muichirou the Mist Pillar arguing with a young swordsmith, Kotetsu.

Muichirou POV

I planned to repair my Nichirin Sword, in the meantime I was walking in the woods to see a boy in a mask with some sort of doll or whatever, though why does the doll look so familiar though, that's when slight curiosity took over and I confronted this Doll and the Boy

"Whoa Whoa wait a second no one told me I was gonna have any wonderers around the Dolls Terrain!" The Masked Boy Exclaimed. My focus was meant to be mainly on the doll but for some odd reason this other kid got my slight attention too, he seemed slightly defensive all of a sudden, I shrugged it off a little. "Listen" I Demanded "What is this thing meant to be and why are you acting so defensive over it." It looks like he was taken back from what I said. "You make it sound like it's not important, I've never met you before so of course you would not know what this is and no offense there is a weird vibe coming you." The Boy Said

As I was thinking about trying to get answers by force seeing as he's talking down on me clearly not knowing his place, I can't help but admire him for his stance. Then in suprise he sighed and explained to me what this dolls purpose was. "It's Called Yoriichi Type Zero, The swordsmith that dating back to the Sengoku period, over 300 years before this period. My descendants built this advanced battle doll modelled after The Legendary Demon Slayer named Yoriichi Tsugikuni and it was used to train swordsmanship and refine the skills of users."

I was a bit Astounded by the history and suprised that someone as him knows this kind of information Though its information that wouldn't matter to me since I'll most likely forget but I do plan as hard as I can to remember this information I just learned, I looked at the doll and the boy. "The only way this Battle Doll can be activated is with this key which is my responsibility to keep it save and to make sure the doll is in perfect function." Upon hearing this I knew that if this doll is what the boys says is true then me as a Hashira is gonna have the privilege to give this Contraption a Test Run. "Give me the Key

3rd Person POV

Few Minutes ago the Masked Boy comes Across the Mist Pillar out of nowhere that gives out this odd feelings towards him, though he seemed to understand and listened about the dolls purpose and it's creation but notice that he got bit to tense when the boy mentions about the key. "Give me the Key" said the Mist Pillar.

"Wait a minute, What are you trying to do! You can't just show up out of nowhere and then call the shots on something that's very important to me what gives!" The boy had his hands in the Air. "I'm not gonna keep asking you this over and over again hand over the key, and don't try to make things more Difficult." Muichirou said with no expressions yet it can still send shivers to anyone. "I said NO" yelled the masked boy.

While The Boy argues with the Older Male they haven't notice the Demon Slayer who's a ray of Sunshine, Tanjiro eavesdropping on the two

"JUST GO AWAY, I'M NOT GONNA HAND OVER THE KEY NO MATTER WHAT, AND FOR HOW THIS IS GOING I'M DEFINITELY NOT GONNA TEACH YOU HOW TO USE IT." The masked boy yelled.
