It's the continuation of the Dragon Ball GT saga. It's not made by Akira Toriyama.. but by Toyble (now known as Toyotaro). But if you read it you would say it's made by him. So this series is not to be confused with the Akira Toriyama Dragon Ball April's Fools which was a hoax.
NOTE: The final volume of Toyble's AF (Volume 5) was never completed past the draft stage. Volume 4.5 is the real ending (for now).
