If anyone is anticipating this game, then you might want to know about Deborah.
In the story, she's actually EXACTLY the same as Flora. She is Flora's sister. You meet them both together in the intro, and they both live in the same house when you consider marrying. They both have the same wedding, and same plot alterations. The wedding is actually the same to the point in which Deborah replaces Flora in the scene; the other sister doesn't even show up at the wedding!
However, in battle, she is very different. Unlike Bianca and Flora, Deborah is more of a fighting type. She has the same spells as Flora, minus Kafrizzle, Midheal and one other spell that I can't think of, but she can use heavier equipment and has some of her own feminine strong equipments. She starts with a weapon called Shiny Nails, which if you know of the killer piercings in DQIV, then you'll recognise the value of the shiny nails in that they hit twice in battle. She also gives birth to black-haired children which IMO are dodgy, but it fits in with the hero and Papas.
