La saison 8 de Duel Masters a été diffusée sur YouTube du samedi 7 avril 2012 au samedi 30 mars 2013. Elle comporte 51 épisodes, le premier s'intitule "The Reckless Class, 5-2!" et le dernier "Wish...".
Who's the kid with the spiky hair?! Meet Shobu Kirifuda, son of legendary (and missing) Kaijudo Master Shori Kirifuda. Shobu's just an ordinary kid, with one big difference - Shobu has the potential to be the WORLD'S GREATEST DUELIST! With best friends Rekuta, Sayuki and Mimi cheering him on, Shobu's dueling skills are increasing and he's learning valuable lessons about friendship, destiny and winning. Under the watchful eye of the mysterious Knight, Shobu learns to harness the power of the Flaming Hand and gains better control over both the ferocious creatures in the Zone and a steady stream of wacky (and sometimes evil!) opponents. Come along with Shobue and his friends as he follows the path to becoming a champion duelist and maybe... someday... a Kaijudo Master!
