The mysterious and beautiful girl known as Nene explains to Taiki and the others about the Code Crown. It is revealed that what they have is but a fragment of a larger piece and that there is a fragment for every Zone. Using the fragment's power to do a Zone Transfer, Taiki's Xros Heart army ends up in the Island Zone, surrounded by a vast ocean.
