I Thought I Picked up a Girl Who Had Fallen Down, but It Turned Out To Be the Future Demon Lord

It’s been 25 years since I found myself reincarnated in another world. I’m a traveler by profession, otherwise known as unemployed.

While I was wandering around, trying to enjoy fantasy from top to bottom, I encountered an injured dragon girl.

As she looked at me, the image of the Demon Lord from the smartphone game I had played in my previous life came back to my mind.

She is a powerful opponent who is a great enemy of humankind, a brave man pulls out his sword and confronts the demon lord to get rid of it.

…But.

In front of me, there is a girl whose clan was destroyed by humans and struggled to survive even if it became tattered.

At this rate, her destination is the two characters of ruin.
