I wanted the dragons to kind of be the opposites of the maids. The maids mainly have black and white outfits, so I used a lot of colors in the outfits of the dragons.
Also, fun fact, their hair colors are the colors in between the maid's hair colors. So when they're all together, they're a lovely gradient of hair colors.
I'm still uncertain of what role they'd fulfill. Originally I thought of the dragon characters would be the villains, however, as they fulfill classes that that the maids don't I can also see them as a part of the party.
The magic user dragon would be a healer, where as the maid magic user would be more focused on destruction magic.
