Hiroto Honda (Tristan Taylor in the dub) is Katsuya Jounouchi's best friend. In the original Yu-Gi-Oh! series, he was a member of the school beautification committee, and was obsessed with cleanliness. He also had a powerful crush on Miho Nosaka, a character who has only appeared in the first series (done by Toei) and in a short arc during the manga, which led him to go to extremes to please her flighty whims.
In the anime, Honda is said to have become friends with Jounouchi while they were in junior high together, back when Jounouchi was part of Hirutani's gang. Honda knows more about Jounouchi than anyone else, even Yuugi Mutou.
In the Duel Monsters anime, Miho doesn't exist, so Honda has a powerful crush on Jounouchi's sister Shizuka Kawai. This causes some friction between Jounouchi and Honda, but they remain good friends. Honda's rival for Shizuka's heart is Dungeon Dice Monsters creator Ryuuji Otogi.
Honda is often seen as Jounouchi's best friend or "wingman," though he doesn't really duel the way Jounouchi and Yuugi do. He dueled only once in the Yu-Gi-Oh! Duel Monsters anime, when he was sucked into the virtual world by Noa Kaiba.
