Hmm... I don't want to be nitpicky and please don't take this the wrong way, but I'm not sure if Kira can sense Rina with the Sixth Senses she has. In a world where high science and magic both exist and are explicitly different, I have always imagined Rina's powers as definitely falling much more on the scientific side of the continuum than the magical. Of the sources for Attributes suggested in the book, I would probably say the were Supernatural, since they're not explicitly genetic Mutations or Technological in nature (though ultimately they were caused by misuse of technology).<br/><br/>This is obviously just my opinion, but I see the dimensional barriers as being an innate part of the multi-verse and not intrinsically having any specific origin, though they can be manipulated by the appropriate powers with any origin. For instance, with her sixth sense for magic, Kira can detect the magical energy from a spell used to tear down the barriers, but probably couldn't have detected the lab accident that gave Rina her powers because that was technological in nature.<br/><br/>Andy, you have an opinion on how this should work?
