The Story begins in an unknown world (supposedly Earth) where scientists have discovered an unknown remnant of DNA with no classification. Several years later they identify it and call it a "dragon". Soon after, an entire dragon is successfully cloned from the remnant. Dragons are mass-produced via cloning labs, and dragon sparring has become a popular sport. The player is shown a picture of Warm City, the player's new home, and has supposedly come to this city to make a name for themselves in the sport of dragon battling.
The player gets to choose from five basic dragon types and two secret dragons. The game also allows the player to receive extra dragons through the saves files of certain games, if the memory card is placed at the second slot. The game also allows a two-player mode, where each player can battle each other with their own dragons. The whole point of the game is to raise a dragon and have it participate in battle. After acquiring high enough stats the dragons evolve into more powerful forms. There are three elemental types in the game: Fire, aqua, and storm. Fire being basic flame control, Aqua referring to water or ice abilities, and Storm refers to electrical powers. Each dragon has an element it is born with, and each species of dragon has certain limitations on how many elements it can be. The elements work in a rock, paper, scissors way of play: Fire being strong against storm, but being weak to water. Storm being strong against water, but weak to fire. Water being strong against fire, but being weak to storm. The goal of the game is to raise a dragon to compete in the Arena with the aim of being the best dragonsage in the land. The higher the rank, the tougher the competition and the more prize money involved. The player can move around the map as needed, but the entirety of the game takes place within a single city.
