One of them must have used the idea of the other. Or some concept artist sold them both the same work and they both used it. Or it could just be coincedence. Nobody knows unless they tell us though

Wow... as if the character design wasn't already generic enough, they didn't even do it themselves.
And Rubi generic? Apart from swearing alot shes not very generic. She covers herself up, her boobs arent huge, her hairs black not a long flowing blond and her clothes seem well designed and intricate, not a strap with her name on it.
