Boundless Sky

Planet Thallasa is a world of oceans. Six vast seas stretch from the tranquil White Sea to the mysterious Black Sea. Only one kind of person dares to sail them: Sky Walkers. Those who leave the land behind in search of adventure, treasure, or challenge. Their power is born from Enjiwa—soul energy that can be shaped by imagination into swords, shields, or even miracles. Yet above all else, there are those born with the Divine Star: a rare power that defies all logic. On a small island in the White Sea, a young boy dreams of becoming a Sky Walker—of sailing the seas, setting foot on unknown islands, and seeing a world he cannot see. He lives on Fiora Island with Millie, a cheerful blonde-haired girl who is always by his side, and a humble family that raised him with love. Every morning, Sidz and Millie sit together in the garden, accompanied by the gentle fragrance of jasmine. That is their small world. A peaceful world. But everything changes when Sidz chooses to become strong. In a vast and cruel world, strength is everything—without it, he cannot protect anyone. And to obtain it, Sidz must leave— Leave his home. Leave his memories. Leave Millie. This is a story of a journey. Of power. And of a promise... to return. From a small island to the vast seas. From a student to a captain. From the oceans... to the stars.
