About
December 20, 2026. The world has unified, but the government has passed a special bill allowing schools to be established as independent nations. While elementary schools are excluded, students from middle school onwards can elect a President, King, or Emperor, and enact their own laws within the school. They can also conduct research to develop weapons, form armies, and engage in construction. By managing budgets wisely, they can trade and export between schools. They can create national flags, appoint Commanders-in-Chief, Generals, and Diplomats, and even wage war to annex other schools or turn them into puppet states. They can demand war reparations or declare ceasefires. Schools can also be given new names. The initial budget is 20 million won, and starting weapons are swords, shields, and bows. There is an approval rating system; if it falls too low, you may face impeachment, rebellion, or abdication. There are no teachers. No one goes home; everyone lives at school. There are no cell phones; messages must be sent via messengers.
