Roland

Roland, known as Isono in the manga and Japanese anime, is one of the Battle City tournament officials. He appears to be Seto Kaiba's right-hand man and business advisor, as he appears later in the anime series to help Kaiba manage KaibaCorp.

In Yu-Gi-Oh! The Falsebound Kingdom, he has left KaibaCorp to work at SIC, and is the one who introduces the characters to the Kingdom game.
