The game begins in the world of Sylvarant, a land that is dying due to a steady loss of mana, the energy source that is needed both for magic and to support life itself. As the crops begin to wither and hardship sets in, the people turn their hopes to the Chosen One, a servant and messiah of the Goddess Martel, who can reverse the ills of the world by completing the Journey of World Regeneration. The current Chosen is a girl named Colette Brunel, who is protected by her childhood friends Lloyd Irving and Genis Sage, her teacher and Genis' older sister Raine Sage, and Kratos Aurion, a mercenary with a mysterious past. Later on in the game, the party is joined by four other people: Presea Combatir, a strong but strange girl; Zelos Wilder, an arrogant playboy that is the Chosen One for Tethe'alla, the other world; Sheena Fujibayashi, a female ninja; and Regal Bryant, an ex-convict.

Such a quest is undertaken when the world is in an extreme state of decline. In order to regenerate the world, the Chosen must travel from continent to continent, awakening the Summon Spirits that sleep at ancient shrines known as "seals". With every seal released, the Chosen comes closer and closer to becoming an angel. Once the Chosen fully transforms into an angel, the world will be regenerated.

As the game progresses, many revelations are made about the subject of World Regeneration and the hidden plots that complicate the scenario. One of the earliest revelations is that becoming an angel forces the Chosen to give up the aspects of himself or herself that make him or her human. With the first seal, the Chosen loses the need to eat; with the second, he or she can no longer sleep. The release of the third seal causes the Chosen to lose the ability to feel physical sensations altogether. After releasing the fourth seal, the Chosen can no longer speak. The fifth and final seal requires the Chosen to give up his or her heart and memory and, with them, his or her life. When this process has been completed, the Chosen's body will become one with the goddess Martel.

The party also learns of a second world, known as Tethe'alla, which lies parallel to Sylvarant. It is then revealed that replenishing the Sylvarant's supply of mana changes the flow of mana, thereby draining it away from Tethe'alla - much like the sand in an hourglass. The reverse also holds true. As the worlds of Sylvarant and Tethe'alla must compete for a limited amount of mana to survive, whenever one of these two worlds is regenerated, the other falls into a state of mana deprivation.

The party does indeed succeed in releasing all the seals, and the Chosen becomes Martel's vessel. However, they learn that the angels that they are trying to serve have been using them. The party is betrayed by one of its own members, who is then revealed to be an angel. The remaining party then goes to Tethe'alla to find answers, where their goal ultimately changes to saving the two worlds. In order to do this, they decide that they must sever the ties between Sylvarant and Tethe'alla to separate the worlds, thus ending the competition for mana. In the end, the party revives an ancient tree of ever-flowing mana, which, with the aid of the Eternal Sword, merges the two worlds once more.
