This story is like traveling onto our native childhood story book, from the character names, Aladin, Alibaba and Simbad down to the setting of the anime story. The original manga of Magi: Labyrinth of Magic is running for 5 years already with a spot on the Weekly Shonen Sunday.
Ha, do you know how hard difficult it is to grab a spot on Sunday releases of Shonen Jump? Sunday releases always have the most sales compared to all days because of its day-off nature. Kids, students or even parents have better chances to buy a manga or two every Sunday.
If you were to ask me, it is the art of the anime adaptation of Magi: The Labyrinth of Magic that made me stick and watch up to its second season and I think I am not alone with that point. Since the manga is still running with on the Weekly Shonen Sunday series, a third season is not a problem for its fans and loyal viewers.
