In the land of Linbalm, a young craft apprentice mistakenly releases a mighty beast from its prison when he/she loses a match to an acquaintance. In order to imprison the monster once more, the hero of the game quests for a legendary demon blade which will lock the beast once again. Upon starting the game, players choose to be male or female - Edge Coltheart or Air Coltheart and journey with a Guardian Beast sidekick. Along with standard strategic battles, players may also enjoy a fishing game and craft over 200 types of weapons and repair/upgrade them for more powerful attacks.
