18. Mezametara Saikyou Soubi to Uchuusen-mochi Datta no de, Ikkodate Mezashite Youhei Toshite Jiyuu ni Ikitai

When I woke up, I found myself inside a spaceship.

I guess you guys think I’m talking nonsense here, but I also have absolutely no clue about what exactly happened to me.

I was really close to completely losing it, but fortunately, I managed to notice that this place was really similar to the world featured in a game I was playing recently.

Am I dreaming? Nope, it’s no dream. Maybe I actually got sent to a different world or something?

But didn’t those things usually involve getting sent to a magical world with elves, dwarves, dragons and whatnot?

In any case, I don’t know what caused this, but I guess I’ll just have to suck it up and live properly in this world from now on.

It’ll be okay. I got my trusty spaceship so I can probably make some money. It’ll work out! It has to!

This is the story of a man abruptly thrown into space along with his private spaceship. He runs around with it and saves damsels in distress along the way, flirts with said damsels, earns money as a merc-for-hire and uses his gaming knowledge to work his way into living freely and easily.
