Kaito, a purpose-seeking teen, embarks on his first real mission to the distant Lunar Province, where he and his squad must stop a looming raid. But the very kingdom hides more than cruel war, from ancient curses and hidden secrets, the queen is pulling the strings.

Luna, that same queen, has her own objectives to pursue, ones that defy the curse placed upon her. As Kaito and Luna's paths intertwine, they find themselves stuck between love and duty, putting everything on the line to free the other from the world's invisible puppet master.
