Harrington Rosewood, known in Japan as Mitsuru Ayanokouji (綾小路ミツル, Ayanokōji Mitsuru), is an Obelisk Blue student who also happens to be the head of a tennis team. He falls in love with Alexis at first sight and desires to date her, much to the jealousy of Jasmine and Mindy. After seeing Alexis being friendly with Jaden, he grows jealous and duels Jaden over who becomes Alexis' fiancée. He loses the duel but makes a vow to always love Alexis while watching the sun go down on a cliff.
Deck
Harrington uses a Tennis Deck, which largely includes "Ace" cards that inflict Direct Damage to his opponents, and "Ball" monsters like Mystical Shine Ball and Mega Thunderball. His signature card, Deuce, turns the duel into a tennis match by restricting the amount of times an opponent can attack, and giving the victory to the first duelist to inflict damage twice.
