Magi: Sinbad no Bouken

Magi: Sinbad no Bouken

マギ シンドバッドの冒険

Not so long ago, mysterious structures called Dungeons began appearing all over the world. No one knows what they are or how they came to be, but adventurers and armies around the world instantly took interest in them. Thousands set out to explore the Dungeons, but so far, not a single person has returned.
In a Parthevian port, a young boy is about to make a name for himself. Sinbad is good-natured, strong, and craving adventure. A kind deed leads to his meeting with Yunan, an enigmatic traveler who is far more powerful than his frivolous personality lets on. Yunan instructs Sinbad to attain the "power of the king" and change the world—by conquering a Dungeon. The eager boy readily accepts, setting out on the grand adventure he so craved.
