Shinichi Kano (voiced by Natsuki Hanae) is an out-and-out otaku. After his first confession was rejected, Shinichi lived a simple otaku life. However, staying at home all the time is not a solution. With this idea in mind, Shinichi decided to go out to work. After a suspicious interview, Shinichi unexpectedly became the "Head of Anmutech". It turned out that a time-space tunnel connected to the other world appeared in the Fuji Sea of Trees. At the other end of the tunnel, there is a country called "Eldant", and Shinichi's job is to go to this country and promote the "otaku culture" he is most familiar with. In the other world, Shinichi met the gentle and virtuous elf maid Fran (voiced by Suzuko Mimori) and the rebellious emperor of the Eldant Empire, Petraka (voiced by Mai Fuchigami). What kind of experience will be waiting for Shinichi when he wanders between the two lovely girls?
