Gameplay and setting
Players act as the Captain of a Savior Party, recruiting star-powered Saviors and guiding them through turn-based battles built around unique skills, elemental affinities, and cinematic ultimate animations. A dedicated training system lets the Captain develop each Savior's stats and equipment outside of combat. The setting centers on the Nebula Observation Agency, an organization protecting a fading cosmos from the aftereffects of the Void Star, which the original Star Savior once defeated. The story follows the Journey, a trial meant to identify a new heir to the Star Savior's power.
