The Imperial Gatekeeper — takes place in a fictional medieval country reminiscent of Japan or China. Recently, there was a bloody civil war in the country, which lasted for years. The Great United War ended after all, and the main character named Till became one of its greatest heroes. The combat veteran still planned to continue his career in the army, but the government promised that there would be no more conflicts and the troops would be disbanded. Instead of the armed forces, the protagonist of The Imperial Gatekeeper offers a job in the new Road Safety Service.
