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. Taking place 15 years before the events of the original series, Magi: Sinbad no Bouken chronicles Sinbad's youth as a Dungeon conqueror. Along the way, the budding adventurer and merchant will have to face many obstacles, but anything is possible with the power of a king.

"Who cares about what happened in Japan's past? It has nothing to do with my life." With these words, carefree high school student Saburou finds himself unceremoniously thrown back in time to the Sengoku Era, landing directly in front of the legendary general Nobunaga Oda. Nobunaga, on the run from his retainers and wishing to rest due to his frailty, beseeches Saburou to take his place, as the two bear an uncanny resemblance. Although Saburou is still confused by his surroundings, Nobunaga hurriedly provides the boy with the necessary items to prove that he is the bona fide feudal lord and makes a hasty getaway. Now a stand-in for someone he doesn't even know all that much about—though his modern experiences and knowledge are sure to help him—Saburou begins his unexpected quest to pose as the man who attempted to unite all of Japan.

Love is love. Someday, the pain of being in love will be an endearing memory. No matter who the feelings are towards, no matter what form it takes, all love and lifestyles have the same value. An omnibus anime tells the stories of “The wedding of an ex”, “a student and a teacher at an all-boys’ school” and “childhood friends whose bodies and hearts change with adolescence.”
