Within the country of Raide, there exists a small secluded village that refuses to acknowledge the existence of those from outside world. It is known as the "Hidden Village". In that village lives the protagonist along with his friend Danette, and other members of the Sepp race. Along with Layna, whose age now exceeds 200, the protagonist helps to protect the village.
One day, the protagonist and Danette are called forth by old lady Layna and given weapons to help guard the village. Danette, who has always dreamed of protecting the village, is overjoyed and is given twin daggers. The protagonist is given a long black sword.
The moment the protagonist takes hold of the black sword, it begins to insult and swear at Layna. Both the protagonist and Danette are profoundly confused at this point. It is revealed that 200 years ago, Layna destroyed the shadow and sealed its soul into the black sword. The shadow goes by the name of Gig. To utilize the power of Gig, Layna chose to give this sword to the protagonist.
The protagonist is infused with the soul of Gig, gaining control of his power, and is now able to fight against the World Eaters, who have now reawakened. With Gig residing in his body and Danette, who has been his friend since he was young, the protagonist departs into the country of Raide to defeat the World Eaters.
The player is given the ability to create and command squads, which, after enough time, will become an army capable of destroying the world her or he is trying to save. Up to 25 different character types can be created, each filling a unique position in the squad with its own strengths and weaknesses. Characters' individual abilities can do such things as increase the range of an effect or give each unit a bonus to its inflicted damage.
