Due to repeated mis-governance, the central government lost its power and it was instead transferred completely to the hands of the regional schools. This in turn led to a struggle for power among the schools, with the government sending spies to each school with the intention of re-obtaining some of its lost power. There was a particular school which did not strive for power and was on good terms with the government, however it was hiding a large secret. It had the ability to destroy the world. The government found out about this and plotted to take the ‘school’s treasure’. What exactly is this treasure and who is the mysterious transfer student?
