@B214 I agree, and IMO the Oriental symbolism even extends in many characters in the series as well. In the main harem itself, we have Rias and Asia (Dragon. Rias is a bit debatable, but the Dragonar armor nullifies that a bit), Akeno and Ravel (East and West Phoenix), Koneko & Kuroka (Tiger, since they are, well... cats.), Xenovia, Irina, and Rossweisse (Turtle, or in several sources, called "Warrior" instead since it is not really a turtle, and turtles are known for their strong defensive shell)
