Safaia Kurojaku, the prince of Kesshogakura. Because Kessho is a monarchy, he is to become the next Safikage and as such is often referred to as Lord Sixth. Jaku didn't go through the academy like other shinobi. Because he was always destined to be the ruler of Kessho, he went through rigorous independent training to get him up to kage level quickly just in case something was to ever happen to his father. As such, he didn't have much of a regular childhood. Now that Kurojaku has more free time, he uses every opportunity to go on missions that are usually reserved from the jonin.
Being a prince, Kurojaku has a personal bodyguard. His is called Tourou, angry bite fish guy. Tourou follows Jaku basically everywhere, even when they're not on missions. On occasion, Jaku likes to run away from Tourou just to time to see how long it'll take his little buddy to find him. He's like that with most of his friends. He likes to tease and joke with them, but ultimately, he loves all his friends. Heck, he loves all the residents of his city. He LOVES his city despite how awful some of the shadier places can be. He has nothing but respect for his people, even the prostitutes in the red-light district. Still, Jaku yearns to travel more...hence why he goes on all those missions.
