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).
He is shown to have a special bond with Kaiba. When KaibaCorp is taken over by Dartz and Roland asks Kaiba what to do, Kaiba answers with “Why do you care? I’m no longer your boss”. But Roland stands up and says that he’ll stand by him until Kaiba Corporation is his again.
