Magi: Adventure of Sinbad

"Magi: Adventure of Sinbad" (also known as "Magi: Sinbad no Bouken" in Japanese) is a spin-off and prequel to the "Magi: The Labyrinth of Magic" series. The anime and manga focus on the character Sinbad, a popular character from the original series, chronicling his rise from a local fisherman's son to one of the most powerful kings in the world. The story starts with Sinbad's birth, which is marked by unusual and significant phenomena. The series then progresses to depict his early years, his first encounters with dungeons (mysterious structures that appeared around the world), and the formation of his own country, Sindria. Throughout his adventures, Sinbad captures multiple dungeons, each giving him control over a powerful Djinn and enabling him to become a force to be reckoned with in the world. He also gathers a group of loyal followers and friends who assist him in his endeavors.
