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. During KaibaCorp-sanctioned tournaments, he also serves as the MC (Master of Ceromonies).
In the anime, he is known for insisting a duel continue regardless of the situation (of course, this was due to KaibaCorp regulations). This was a running gag throughout the series. Often, he would continue talking about the duel, when there were bigger issues at hand. Tristan Taylor and Joey Wheeler were aggravated because of this.
Fuguta, in the English dub, is once incorrectly called by Mokuba as Roland.
