The story follows Lucky — a young Umbreon who left his hometown to search for answers about his family within the walls of the Expedition Society. He meets the famous explorer Sylveon named Pix, the Society’s Radiant Icon, who unexpectedly becomes Lucky’s mentor and partner on future missions. Some think their partnership is doomed from the start, but only time will tell whether opposites truly can’t work together or if they’ll forge something unbreakable.
