Tales of Symphonia The Animation: Tethe'alla-hen

Lloyd Irving and his companions cross from Sylvarant into Tethe'alla, the flourishing world that exists on the opposite side of the struggle for mana. Their immediate goal is to save Colette from the condition left by her failed journey of regeneration, but entering a new world exposes them to a society, technology, and political order very different from their own.

New allies such as Zelos Wilder, Presea Combatir, and Regal Bryant join the journey while old enemies and the organization Cruxis continue to manipulate both worlds from the shadows. As Lloyd searches for a way to protect Colette without sacrificing either world, he is forced to question the system that makes one land prosper only when the other declines.
