Mai Kujaku of Yu-Gi-Oh (Mai Valentine in the English anime) is an attractive woman who spent most of her life alone.
While working as a blackjack dealer on a cruise ship, she developed a cynical attitude towards people and showed no shame in manipulating men, who displayed foolish infatuation towards her and previously used her "Aroma Tactics" to easily beat them in card games.
Mai is voiced by Haruhi Terada in the Japanese series and originally by Megan Hollingshead, then Bella Hudson (Season 4) for the English adaptation, and finally Alyson Johnson for the 4Kids Uncut adaptation. Her English name is a reference to "my valentine".
