Jiro is a headstrong kid that is set on revenge for all of the destruction Nene has caused. It has been assumed that Nene may have burnt down his village and taken his entire village (or kids) hostage, just like what happened with Shu's village. Jiro is constantly causing rifts between him and Shu, just to make their rivalry that much more of a "rivalry." He has been traveling with Zola for some time now and knows about "The Book of Origins" and the history of the Seven Warriors of Light. He is the complete opposite of Shu, leading them to their rivalry. But the one thing they both have in common is that they both have the strengh and willpower to defeat the Grand Kingdom if they try hard enough.
