Isekai Rebuilding Project

Have you ever wondered what happens after peace is restored in a fantasy world? What happens beyond the final page of an Isekai light novel? Eiji, a thirty-year-old Japanese city clerk with a thoroughly average life and a fiancée, had not. He too answers a call to be transported to a fantasy world, but not as a hero. This fantasy world, having already been saved by a hero, was about to collapse for another reason entirely... thanks to that hero, who was also summoned from Japan. Eiji is tasked with restoring the fantasy world to its authentic form: how it was before it was infected with the technology, ideology, and societal concepts of modern-day Japan.

After running wild to save the people of a fantasy world from an anachronistic beriberi epidemic, Eiji and his dragon companion Tiamat discovered the root cause of the world's deterioration. Accompanied by Baze the Fenrir and Hieronymus the Cait Sith, they now embark on a new journey. Tagging along with the Murdock Troup, a traveling circus, they arrive at the kingdom of Noura, where Eiji and his party will face down an entirely new challenge.
