Without Him...The Minato Tribe struggles to continue on after losing both their last match and Shun's life. However, Minato barely has time to mourn when Saori is kidnapped by a biker gang, the Adachi Tribe, and forced to play a game of XB on Adachi's turf to rescue her. Adachi's home "field" is set in a large shopping mall, full of enclosed spaces and alleyways that make finding the ball and the bases difficult for Minato. In addition, the Adachi Tribe are able to use their motorcycles as "spikes" within the rules of XB, making it difficult to evade them or tag them out in time...
