* How are Kyouka or Gekka candidates to be Enka's child if [[spoiler: they're thousands of years old or more]]? Could [[FridgeLogic Enka's children have been around for centuries and only recently cataloged by the Paranormal Bureau]]? How many candidates are still unknown?
** With Kyouka it could make sense if it's [[spoiler:[[EmptyShell the body]] [[DemonicPossession she's taken over]] that is Enka's child and]] not her.
** Gekka created [[spoiler: an entire race from herself (the Water)]], does that mean there may be more candidates [[spoiler: among them]]? [[spoiler: Or did she [[MindRape fool the test operator]] like Kyouka did for Chika]]?
** Given that [[spoiler: Gekka is thousands of years old and capable of some sort of pathenogensis, Enka might have ''her'' DNA not the other way around. In other words Enka is a lifeform derived or descended from Ocean or Gekka herself. [[WildMassGuessing Or actually was a form of Gekka herself]] when she was enraged by something.]]
