Are there other unresolved questions on esper powers?

Well, there's the thing about Gemstones. Aisa manifests an ability that's the bane of all vampires, Gunha's powers appear to come straight out of a superhero comic, and all we know of the Gemstone Girl is her sound-related ability. There doesn't seem to be any particular "pattern" when it comes to "what comprises a Gemstone ability", but I guess that's part of the "natural" aspect of Gemstones.
