Diego is a famous swordsman in Lost World. Diego first became a true sword fighter at the age of 23. When he was 44, Diego abandoned his love of sword fighting, because of something dreadful in the past. Jose then convinces Diego to become who he truly was. It's been a long time, so Diego's techniques are kind of rusty. The Blue Fang gang then appears, and that's when Diego shows himself worthy to take tests of the WAY OF THE SWORD.
