Yamato Versus the Masked Marble Part 2 Food Fight

The Lion's Den is the thirty-seventh episode of the Battle B-Daman series. It first aired in Japan on September 13, 2004.


Assado returns to join Yamato and the others after finishing his B-Daman training journey. He offers to take them to see the B-Daman Academy he's attending. But something strange is happening to all the students. Does Marda B. and the Neo-Shadow Alliance have anything to do with it?



Featured B-Da Battles


  • This is the first episode where Cain McDonnell and Joshua join the Neo-Shadow Alliance. This is ironic in a way, because Cain previously destroyed Cobalt Blade, when Marda B. wanted it. So they were indirectly working against each other previously.
