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.

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.

His new life includes everything he once lacked: loving parents, a comfortable home, and a promising future breeding and raising birds on his dad’s ranch. For centuries, the kingdom he now calls home has enjoyed peace and prosperity, shielded by friendly nations that, like Shiyalta itself, were established with the collapse of a once-great empire.
