Roland, known as Isono in the Japanese version, is one of the Battle City tournament officials. He appears to be Seto Kaiba's right-hand man and business adviser, as he helps Kaiba manage KaibaCorp. During KaibaCorp-sanctioned tournaments, he also serves as the MC (Master of Ceremonies).
In the English dub, Fuguta is once incorrectly called Roland by Mokuba.
