Yamato obtains a special B-Daman "blaster" named Cobalt Blade, which an evil organization called the Shadow Alliance plans to steal.The show ran for 1 season in America (2 in Japan). However B-Daman did not meet as much success as it was expected.The show had two spinoff Gameboy Advance titles, which sold poorly because they were released after the Nintendo DS made the Gameboy obsolete.Here's the Character Page.

Break the Cutie: Poor little Enju was forced to take a dive on each of his battles so his dad could pay for their rent. At the Junior B-Daman Tournament he was disqualified after unfairly being accused of cheating due to his refusal to repeat his past life, thus being betrayed by his only friend, Enju took out his anger on his father in a B-daBattle, resulting him into changing his hair from blue to red and changing from timid and meek to cold and ruthless.

Love Martyr: Liena continues to long for Enju, who clearly is interested in B-da battling and becoming stronger.
Joshua in the first season. He was fine with Cain's arrogant attitude because he remembers a time when his master was kind.

He succeeds.
