This story is slightly different than usual. Brian “Brainy” Hedgehog is now the son of Shadow and Maria. Brainy doesn’t have many friends because of this, but is quite popular. But not as popular as the daughter of Sonic and Amy, Aurora. One day, they finally cross paths when both families are invited to Tails’ reunion dinner party. Both Brainy and Aurora are performing as live musical entertainment. Sonic and Shadow want them to be rivals, but they see each other different than their parents hoped.
