A divine being created the AOTU World and assigned the 7 Oracles as its rulers. The deity has predetermined all aspects of social standing such as poverty or wealth, slavery or freedom, pain or pleasure, and destruction or creation. Mortals are bound to submit to their fate without any choice. However, due to the AOTU Contest, humanity has been given a chance by the god to change their destiny. The Contest System provides participants with unique "abilities" and encourages them to develop their own wisdom and courage to win the tournament and become the world's rulers.
