Intergalactic king

When I woke up, I found myself in space, moreover as prince of a space nation .

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

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?.

it is a story of a gaming otaku who reincarnated as a prince of declining space nation and how he conquered the intergalactic
space.....
