I found Accel World's light novel and the manga on Amazon. My question: Is the manga the completed story? The manga has 8 volumes and the last one will be released on December 11, 2018. But the light novel has 17 volumes and the last one will be released on March 19, 2019.
So is the manga the whole story? Or do I need the light novels if I want to read the whole Accel World? If so, is it because the light novels have more volumes and will be released on 2019 while the manga is only up to 2018 so the manga does not have the completed story? Or is it otherwise?
