When Satou Takahiro is swept away from his ordinary life into the world of his favorite video game, a universe of space battles, interstellar colonies, and danger in the vastness of outer space awaits.

Seventeen-year-old Hajime Nagumo is your average, everyday otaku. However, his simple life of pulling all-nighters and sleeping in school is suddenly turned upside down when he, along with the rest of his class, is summoned to a fantasy world! They're treated like heroes and tasked with the duty of saving the human race from utter extinction. But what should have been any otaku's wet dream quickly turns into Hajime's nightmare. While the rest of his class are blessed with godlike powers, Hajime's job, Synergist, only has a single transmutation skill.

Magic powers? His own mech? A whole airship of gorgeous women desperate for his genes? Yes, please! Paralyzed by a drunk driver, let go from his job, and stuck in a sad, stagnant town in the middle of nowhere, Joseph Locke was having the worst day of his life. And then he died. But considering that he wakes up with a brand new body, in the cockpit of a badass steampunk robot, on an airship of nothing but hot babes, his next life may not be all that bad. Especially when he learns that he’s a void mage—the rarest and most powerful of all mages on the world of Haven.

When Kazuya Souma is unexpectedly transported to another world, he knows the people expect a hero. But Souma's idea of heroism is more practical than most—he wants to rebuild the flagging economy of the new land he's found himself in! Betrothed to the princess and abruptly planted on the throne, this realist hero must gather talented people to help him get the country back on its feet—not through war, or adventure, but with administrative reform!

The usual result of a human taking a runaway semitruck head-on is a very sudden, very fast track to the pearly gates. But for one newly noncorporeal man, there's another option: become a dungeon. Feeling sorry for the desperate angel assigned to him, the man relents. Heck, if it doesn't work out, he can always chat with Saint Peter about it later. Next thing you know, he's a dungeon. Admittedly, a small run-down, somewhat unimpressive dungeon (more of a house, actually), but you gotta start somewhere, right?
