Rintarou is the leader of Jurren Village which the Ogame School uses to train.
Rintarou is a average adult with slicked back blonde hair. He wears dark colored jacket with the Ogame School symbal on the back and both sides of the open jacket, yellow kimono, over a black one under neath, a black sash, and sandals.
Apparently, Rinatrou sports a rather goofy and funny personality, often joking and laughing, even during training. However, he can also be very serious and stern when he has to, usuallly when he's fighting someone seriously.
Rintarou was born in Holland where he, some time in the past, embarked on a ship but ended up on the shore of Unabara because of a shipwreck. He met Jinsuke Kurogane when he was younger, who apparently saved his life.
