"My my my...this is such a new setting, it's truly amazing" you smile as you looked up from the crowd of people. Walking silently from the street of England you have finally arrived near the destination of your new assignment. Multiple reports have said odd behavior of people dying and disappearing without a trace has been going on in England. You were one of the Pillars; from an organization originated in Japan from centuries ago of swordsmen who hunt down Demons and protect human beings. Your Master had to assign you out of the country and hunt down the demons causing this, but something was off.

The body's left or discover were not eaten; not even one. Which was odd to say at least for a demon. Another part of you thinker with the information that was given to you. Your Master had told you once that there where demons who made contracts with humans, mutual agreements between these two until the human's desires are completed, the demon will feast on them as their part of the deal for being their servants until the end of the contract. It was a troublesome thing since the demons are under control of a human the harm that a demon Slayer can do on them is limited if a human is involved in controlling these creatures.

You sigh as you kept on walking down the road; people look so different. The atmosphere unique from anything you have gone through before, it was almost welcoming, but behind it...you could sense negative emotion ever since you step in this country. It seemed to overpower all over. How saddening you glanced up to the road, forestation started covering it. A loud squawk interrupted your thoughts, a crow flying above you before descending on your shoulder. "Y/N L/N!! Your assignment is up ahead in nearby wealthy Mansions around the area, noble families seemed to be involved! squawk locate the demon causing havoc in England and stop them!!" The Crow screams at your ear. You didn't even flinch instead, you petted its head with a finger. "Thank you for the update on information" it let out another high pitch squawk before it flew off your shoulder. "I guess there is no more time to waste now" you whisper out before jumping on a tree with ease. "Not when people are on the line.." you kept jumping between them, you looked like you were flying on air. You inhale softly as you close your eyes. Don't let them bring anymore bloodshed on the innocent y/n...

Soon enough you were faced with a Mansion, it was far larger than any of the buildings you have seen so far, it had you taken back. It looks like a castle from a scroll you have read from countries out of your own. "How beautiful..." You mumble out as you slow down your pace as you stop on a branch. Scanning around the area with curious eyes, everything seemed quiet from the outside, but the scent... The scent was so sudden that had you holding into your nose in surprise. "One..? No no two?" You mumble out to yourself as you tried getting a better scent, the aroma left different trails all around. The small scent of blood hidden around the forest. It felt like it has been there for maybe months? You squinted your eyes, the sudden sound of doors open as someone darted out. You hold onto the handle of your sword as you watch a blonde boy run out chasing after a cart. "AHH wait wait wait!!" He screams out with tears in his eyes. You blinked several times, he smelled human but something was different about the kid. You jump down in front of the cart, your hand extended as you stop it in a harsh halt. The boy crash into it by its sudden stop. "O-ow.." he pulled back as he rubbed his face. "Are you alright?" You poke your head around the cart to look at him. He had a farmer attire, he looked young as well. "Huh?" He looked startled by you before wiping his face. "I'm okay! Where did you come from? are you a guest from the young master?" He tilted his head, completely forgetting about the sudden injury in his face. You just smiled back at him, "no I'm just a traveler, I'm looking for something here, would you be kind enough to help me? It's been long since I stop to rest, do you mind if I take a breather I promise to pay back" you bowed your head at him, he seemed startled by it but you pay no mind. "Oh no! You been traveling for so long? I think Mister Sebastian won't mind if we help, follow me please!" The boy grabbed the cart with one hand and the other motion for you to follow him. "Thank you so much for your generosity"
