For female characters to be added to the game, there first must be female characters from the series, of which there isn't a huge amount of. Off the top of my head, I can only think of Blair and Serenity that have not been already added to the series, the latter having little reason to be added.
I'm worried about Zexal world, as we'll only going to have Anna and Rio as the female duelists, both sounds like they're gonna be introduced later instead of sooner if we're looking at when they show up in the anime. Cathy is an early female duelist, but she is just a support character and half of her deck is unreleased in real life, so I doubt they'll make her playable in DL......
Someone without a deck dueled three times on-screen... How does that work, exactly? Admittedly only one of them was a full duel with her own physical cards, but still. That being said, even TRISTAN owns a deck.
I strongly disagree. This game actually needs a lot of "hot" male characters since the series itself is already masculine in the most literal sense, and its catered demographics is the shounen category. Hence, this should be balanced out by creating more stronger female leads like Alexis.
