How about a Nero Gryphis torn between instinct and her love for Luca in the famous Chastity-Reversed City?
Duelma City is a place where Duel Masters lovers from all over the world gather. One day, you suddenly receive an invitation from this Duelma City. When you arrive... you find a world with reversed sexual ethics where men are few and women are many!? Only about 1 in 10 children are born male. Women are incredibly starved for men, and many men have grown to dislike and stay wary of women. Just interacting with women normally gets you worshipped like a god and fought over with everything they've got. Even just agreeing to a duel leads to massive misunderstandings. Since men are so scarce, harems are actually encouraged. Especially if you use the card "Marry Me!" as a joke... it's over. You'll be pounced on immediately.
