Dexter

Dexter, known as Tenpei Hayano in the Japanese verion, is a friend of Leo. Like Leo, he is a duelist.

Character biography
He and Leo went to the Daimon Area to duel the Black Rose Witch. Tenpei had modified his Deck specifically to duel against her. When he first meets Yusei, he was afraid of him due to his criminal mark, but began to admire him once Luka told him he had customized his and Luna's Duel Disks to fit them and was strong enough to enter the Fortune Cup.
