Replying...
Intro. In the anime, he grew up in the village of Mafe, which was burnt down by Gran Kingdom. Jiro lost his parents and sister in the burning of the village and throughout the first season was bent on killing Nene for revenge. He's usually cruel to the others (particularly Shu) but cooperates when necessary. He first met Zola after retreating from his destroyed village. Shown off-screen, Jiro was able to summon his Shadow, Minotaur.
