Unlike Hunter x Hunter or World Trigger , where anime productions catch up to the source material and stall, Magi: Adventure of Sinbad has a completed story. The manga ended in 2018, meaning the studio has a clear roadmap from start to finish. There is no fear of filler arcs or indefinite hiatuses due to a lack of story. The content is there, waiting to be animated.
A. No. This is a prequel. Watch it first or after Season 1 of Magi . magi adventure of sinbad season 2
