After their near defeat in the exhibition match, Ikki and Koji are worried about how they will fare in the championship, especially as Space Medafighter X still hasn't turned up. While the two start arguing about who is going to be team leader, they rescue a little girl from the Caribbean team and let her watch them training. When the robattle begins later that day, Karen has to take MedaX's place yet again, but as the robattle begins they realise that the girl they helped was actually the daughter of Team Caribbean's leader. As the Caribbean rips through Team Japan, the three have to work together in order to defeat their opponents and make it through to the next round. With the three friends finally working together, Henry decides that it is time for the real Space Medafighter X to make his appearance, but how will the team fare against the rest of the opposition.
