Miina Malina
Miina had slowly inched closer over the course of the explanation, freezing at Rudolf's attention, only to continue her slow onwards progression once he continued. Maybe with a little extra magic involved, to dampen her presence in every sense she could think of; better to be uninteresting than missing.
Why? Well, she didn't want him spooked. Not until she was close enough to almost be touching, golden eyes flicking all over Rudolf, narrowed into conspicuously feline slits. If he hadn't noticed that attention, there was no missing when she started giggling from this close.
"F-F-Fascinating… it's so interesting," now that she had the space from the medical demands, the idea of binding an entity of black magic to yourself… well, Miina had no interest in doing that; it would cripple her in no short order when she tried to channel its antithesis, and she didn't want to give up white magic anyway. "D-D-Does it hurt? Have you th-thought about trying b-black magic properly?"
She couldn't see why you couldn't learn to use it intentionally if you were already pulling on black magic to do all sorts of things.
…
If everyone else overreacted, that would be annoying. She didn't want to leave, and abandoning her cousin on such a deadly task would be kind of unpleasant, but new magical knowledge was so enticing, and it wasn't like they were really on a course to run into her brother, now.
But then again, the Kirins might also find some white-magic equivalent, and Esben was summoning things, and there were the crystals themselves…
