"You... Have the same name as me?"

"I'm not lying. I can show you my ID." Her hand reached for her pocket. "Here, see?"

I moved closer.

(Yukio Minori, Year 4th, Class C. Date of Birth: 1/08/20XX.)

A small photo of her was on it and the design looked similar to mine-- no it was exactly the same. I took my ID from my pocket to compare mine with hers and...

" Ignoring the photo... They're both exactly the same."

She wasn't lying? I'm baffled on how this is possible. She couldn't have copied it back in the real world unless...

In front of me, she crossed her arms, "Listen. I don't understand why this is happening. Just a few minutes ago, I was in a dark room and when I came to, I somehow ended up here."

Dark room?

"You too?" I asked her, "When I arrived home from school, something dragged me and I ended up in a dark room too."

"Wait. That's exactly what happened to me. Did you see a bed?"

"Yeah, It was in the middle of the room right? When I tried lying down on it for a bit, next moment I opened my eyes, I was in that room." I pointed at the door that I closed.

"..."

She remained silent. Her face looked down on the floor and seemed to be reasoning what I just said.

"Could it be... No, that's the only explanation left."

She was talking to herself for a moment and I managed to hear what she just said. I also ended up focusing on the exchange we just had.

Everything was the same. I can't argue with that. No matter how much I rechecked our ID's, every piece of information was the same. The only difference was that the person in front of me was of different gender. How could there be an explanation for this?

Then it clicked. There was an explanation for this and there was only one.

Coincidentally, both of us looked at each other and opened our mouths at the same exact time.

They didn't care if they would interrupt each other. They just wanted to say what they had just thought because it had to be spoken.

"Are you... Me? From a parallel world?"

"Are you... Me? From a parallel world?"

Both of them reached to the same conclusion. It was indeed the only explanation left. After all, this was in another world, an isekai. Anything could happen in this genre. They were only confused because they still kept thinking as if they were in the "real world". But, only now they realized that they don't have to do that here.
