Wakfu: Chronicles of the Lost Ninja

Never let your guard down, that is the number one rule of a ninja. Unfortunately, Naruto had never been very good at following that rule and pays for it when Nagato seals him away for the good of the future. Thousands of years later, he reemerges to a world much different to the one he left. (New cover made by DylantheArtist, full-sized image on my Deviantart account)
