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. was taken by Dartz, he asked Kaiba what to do, Kaiba answered with “Why do you care? I’m no longer your boss”. But Roland stood up and said that he’ll stand by him until Kaiba Corporation is his again.

In flashbacks from the manga, it was shown that Roland knew Seto since his step-father adopted him, and that he was the only one to help him after Gozaburo abused him — thus showing that his and Kaiba’s relationship is more than just the kind between an employer and work employee. He also has a very good connection with Mokuba — making him one of the rare persons who is close to both Kaiba brothers.

In the English dub, Fuguta is once incorrectly called Roland by Mokuba.[2]
