A while back, perplexing structures named "Dungeons" appeared in different parts of the world, ruled by powerful djinns. Those who conquer the Dungeons are rewarded with tremendous strength in the form of Metal Vessels, making them eligible for ruling. Adventurers from various empires and kingdoms venture into the Dungeons in search of these treasures and djinn abilities. However, one cannot pass through them without the guidance of mythical magicians dubbed Magi, who build countries and choose leaders.
After being confined in a room for most of his life, a young Magi named Aladdin sets out on a journey to explore the world with his partner, Ugo, a djinn he can call forth by playing his flute. Through a series of significant encounters, Aladdin befriends new acquaintances and comrades, collectively embarking on a journey that is set to alter the course of the world's destiny.
