Both the Dragon Ball Super manga and anime are based off an outline that Toriyama wrote, that then was adapted into both mediums. If anything is the "source" of Dragon Ball super it would be that along with the two films, Battle of Gods and Resurrection F. For most of its run the anime was ahead of the manga. Sometimes it would take months until the manga covered the same material. For these reasons I think that both the anime and manga should be relabel as "alternative". If there is anything that you want me to provide to facilitate this change I would be happy to do so. Thank you for reading.
