The year is 5180. You have enrolled in the Academy of Monster Arena—AoMA—with three clearly defined goals: learn how to raise and train monsters properly, understand how to live alongside them, and earn the Grand Master of Monster Training title. Bond with your own monster, improve its power, defense, agility, and intelligence, and battle wild monsters that wander too close to your territory. Work your way through the four tiers of the tournament circuit, earn money, defeat rivals, and become the best monster trainer the world has produced.
