Well, Whaddya Know, Another Isekai Light Novel!
The year is 20XX, and Shinichi Kanou is a pretty typical otaku: he loves anime, manga, games, and light novels, but his devotion to the two-dimensional hasn't always made him the most popular guy around.
What he doesn’t know is that Japan has discovered a portal to another world in the vicinity of Mount Fuji. The government sees a great chance to make a profit, if they can keep the secret long enough to corner the market on exports to the Holy Eldant Empire, their point of first contact with this new land.
The people of the Eldant Empire, though, only have eyes for one of Japan’s traditional exports: pop culture. When it quickly becomes evident that government bureaucrats and “Japanimation” don’t really mix, the bigwigs realize they’re going to need help bringing “otaku culture” to the Eldant masses.
Enter Amutech, a purveyor of “general entertainment” that’s secretly run by the Japanese government. Shinichi lands a job as the company’s general manager, whereupon he learns the state’s biggest secret. Now he finally has a chance to put his nerd know-how to good use spreading the otaku gospel in the Eldant Empire. And wait... he has to work with a half-elf maid, an empress, AND a female soldier to get the job done?
