It was supposed to be a normal morning for Twilight, it was now a lazy Sunday afternoon. Anya was busy munching on her toast with fried eggs and butter (which was of course, made by Loid himself) Yor was busy unpacking a new packaged box which she had just received the night before.

However, it was from an unknown source.

Twilight, being all suspicious of everything and all. Decided he would open the box up. While having Anya and Yor peering over his shoulders.

Suddenly, the box started to shake, it trembled in the palm of Loid's hand. That's when a light had engulfed the trio into the box. The three were transported into another world. Anya's mind started to spin, Yor was closing her eyes, afraid of what was going on. While Twilight had to keep his eyes open, fearing that they were in the hands of unknown enemies.

...

On the other side of the universe, on the very old timeline, there lied a girl with a pink dress. She was busy holding the bags of food to bring back to her family, her family who was her big brother: Tanjiro, and her close friend: Zenitsu.

(Sorry, please don't ask where this is coming from, it's mostly in the setting of AU, but I looked up that Demon slayer was placed in the Taisho era 1912-1926. So, I'm writing down some references is all)

Nezuko was her name. And she had a job, which was bringing back tasty food for her family. As she made her way up the stairs, a round circle in the sky appeared before her. It opened up a tear in the space above her, that was when a small girl with pink hair, had fell out from the sky.

Along with a woman who had black long hair, and a man wearing a suit with light coloured hair.

Nezuko quickly hid behind a tree.

...

Twilight quickly got back up from the drop, he dusted off his suit while looking around. He also checked if Yor and Anya were ok. They were all good. As Twilight looked around the place, he felt a piercing gaze not too far from where he and the others were. He called out.

"Who's out there?"

"..."

"Come on out, I know you're here somewhere"

"..."

When Anya had a feeling that Twilight was looking if anyone was around, she used her mind powers to track down any thoughts. She heard Nezuko's voice.

'I can't speak. I wish to help them, but brother said to stay away from strangers'

'I don't know who's here, but I have a feeling someone is watching us...'
