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.

Despite her potential to be the second highest scorer in the level, she obtained zero marks for having left due to her illness and is thus banished to the worst class, Class F.
Grades mean nearly everything. For Class A: They have a smart-looking teacher, a plasma TV as big as the entire wall as their blackboard, personal laptops, personal air-conditioners, refrigerators, adjustable seats and all kinds of different appliances. Within the refrigerator, there are all kinds of drinks and snacks. Their ceiling is made of glass, the wall lets them put up high-class drawings and plants.
As for Class F (the worst class): They have Japanese desks and seat paddings. Their blackboard is dirty and there's even no chalk! Someone complains the legs of his desk are broken, so the teacher asks, "Didn't we distribute some glue to stick wood together? Glue it back yourself later." Another one complains the wind is blowing in from the broken window. The teacher says, "I got it. I'll apply for plastic bags and super-glue to fix it later." There are spider webs everywhere, not a patch of the wall is clean. A unique moldy smell spreads across the entire room; it must be from the old tatamis used to tile the floor. Welcome to Class F.
The protagonist feels displeased at such an arrangement; he seeks help from his friends to try to make a change through invoking war! And they devise all kinds of plans to try to beat the famous Class A, scheming to get Class A's classroom and equipment if they win.
