A romance story through the "masks" they wear to war.

Having a light novel author father and an eroge illustrator mother, Kanou Shinichi is a thoroughbred otaku. However he does not have any special power except for his broad knowledge, sharp insight, and impeccable instinct about "moe" and its products, from manga to anime to games to light novel to figures. One day he found himself transported to a fantasy world where elves live and dragons fly. And he is given a task—not to fight monster or embark on a quest, but to enhance cultural exchange by becoming a "moe missionary" in this fantasy world! He meets a palace guard who has a bit of fujoshi taste, a half-elf maid, and the empress who is a little girl. He comes up with the idea of building a school. At first it runs as a comedy but later there are serious matters that Shinichi needs to face: ethnic discrimination, social problems, conflict with neighboring countries, sabotage by opposition elements including Japanese government and the likes. Can he overcome the obstacles, successfully bring "moe" culture to the fantasy world, and help the people there as well? Adaptation of the light novel series written by Sakaki Ichirou with illustrations by Yuugen.
