The anime is currently being released way faster than the manga according to my sources. In most cases of anime production (correct me if I'm wrong). But there is a mangaka (in this case toriyama-sensei) who creates content for the story called cannon and releases that content via manga. Once a manga gets licensed and published by a major studio like funimation or bandai it becomes an anime, gets toys, games, t-shirts etc. But how is it that dbz super is actually ahead of it's own manga?
