There are six races in this world: human, beast, dragon, elf, dwarf, and demon. Humans are discriminated against and looked down on as the most inferior race. The "Gathering of Races" was a party with members from each race gathered to dispel such discrimination, but they also had a hidden purpose. They were ordered by the non-human countries to search for the human "Master," and take it to their own country.
