Overview
In the near future, a disease has made it almost impossible for people to have children. To keep the country from dying out, the government takes over. Every young adult is sent to a special academy, given a score based on their body and their "breeding value," and ranked. Your rank decides the rest of your life. Reach the very top, and you - and one person you choose - get to walk away free and stay together. Land at the bottom, and you spend your life serving everyone above you, never allowed to have a family of your own. Love doesn't matter here. Only the breeding result matter

Developer Notes
S Rank Breeder is a story-driven dystopian breeding-academy VN told through two protagonists on opposite ends of the rank system. The game leans heavily on its phone, Chirper social feed, encrypted video calls, and a clinical "Academy Evaluation" app that lets you watch how characters are scored, trained, and changed over time. Chapter 1 sets the board; later chapters open up corruption, voyeurism, and the routes that decide who walks away free.
