The Courier by SkyCatNovels

Only a small number of the population are given the permission to walk beyond the town walls. Those people are either members of the Syndicate or employed as couriers. Couriers take on the difficult task of transporting important objects and information between the human settlements- a thankless and dangerous job, often chosen as the last ditch effort to preserve one’s freedom or life.
Some people are drawn to the adventure associated with the job though. One of them is the main character of the story. A man that is sure going to change the course of the history. Of course he needs to stay alive long enough to achieve it.
The visual novel is based on story and character development. This means, that the sexual content will be serving the story and not the other way around.
