Manabu Yamaji

Manabu Yamaji (山地 学): Tetsuzan's young son, a 9-years-old third grade student. He becomes dissatisfied with himself after feeling that his older siblings and father treat him as being only half-capable as they are. He eventually creates a homemade battle armor as he becomes more involved in the war against the Sorcerers Clan, while using a slingshot as his weapon. He is also a talented artist when it comes to drawing portraits.
