In another world, the Bedaworld, balls from ancient times are admired and a game called Bedaman, fought with those balls, develops. Daiwa Yamato is a young boy with quite the Be-Spirit. Yamato is chosen user of the "Kobalt Blade" by the rulers of Beda World, the Beda-Magicians. One after another, Yamato is attacked by members of the evil organisation called "Shadow". Are the true aims of "Shadow" to rule the Beda World? Or do they want something else?! Growing up with burning battles and without trustful friendship, what could possibly be lying on Yamatos paths.?
