The 4 season of Duel Masters was broadcast on TV Tokyo from samedi 6 octobre 2007 to samedi 29 mars 2008. It consists of 25 episodes, the first one is called "Duel Start!" and the last one "A Soul-Summoning Special!".
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!
