Permission granted. Feel free to make a character thread for her, and I'll give you her currency numbers.
I'd say that she should have an appearance consistent with the kind of demon-kin she is, like with her eye-color and stuff... but Scorp was the one in charge of deciding those details about succubi, and I'm not even sure we're holding to the whole idea of certain demon-kin having certain eye-colors, except in specific situations (like I know all Malice demon-kin have red eyes...)? So - this is fine.
Oh, well, if you would prefer her to have different colored eyes, that can be arranged. I just stopped there because I was wondering if I was adding too much for a half-demon XD
