Baten Kaitos: Eternal Wings and the Lost Ocean

An unseen Guardian Spirit meets and guides Kalas, the story’s protagonist. Kalas is considered a bit of a hooligan, and an outcast due to only have one wing, with the other being replaced by a mechanical wing. He travels the world to seek revenge for the death of his grandfather and his little brother. Eventually, his priorities shift when he meets and travels with a young woman named Xelha, and accidentally releases one of the five End Magnus, loosening the seal on Malpercio. The two travel to prevent the corrupt Alfard Empire from fully releasing Malpercio again, eventually joining up with Gibari, a laid-back fisherman from a small seaside town, Lyude, the ethical son of a powerful family in the heart of the Alfard Empire, Savyna, a skillful ex-mercenary, and Mizuti, a strange masked creature from unknown origins.
