One of the pirates going to great lengths to attain the treasure is El Drago. He and his crew have hunted down Woonan's former crew members one by one, and along the way, they find the map that will take them to the hidden island.

The map is not all they come across; they also manage to come into contact with the straw hat pirates. After a short battle, Luffy and company are robbed and separated from one another. Now they must find a way to make it to the island before El Drago does and take the legendary treasure for themselves.

But before he can do so, he is double-crossed and banished from his own kingdom. To return home, Alfonso sets out to find the help and strength he needs to reclaim the throne.
