Nabuca

He is one of the children that have been previously captured by Hamdo and forced to fight as soldiers. He is a good soldier and seems to be loyal in a mixed sense; he is hoping that when he has fulfilled his duty, Hamdo will free him as promised. He's the leader of the group of soldiers that Shu gets assigned to and is one of his main 'contacts' among them, although they often dispute about philosophical aspects and fight each other. He resents Shu for having saved him while they were fighting.
