She is sitting in the library, studying. It's her most common pastime, by hours; spending time with her sister is more enjoyable but Jaromira prefers to socialize more broadly and Katarzyna would only get in the way. This is better on net; the two of them share a room, so it isn't as though her sister's time is entirely hogged by the other girls who call this boarding school "home." Or at least "prison." Katarzyna doesn't mind it, though; the school library is excellent, and basic manners and care for the books has endeared her to the librarian to a sufficient degree to lubricate the interlibrary loans process when there's something she wants to read that they don't have.

"Okay, I know I've seen magical girls with crazy hair...can you make your hair unaffected by gravity?"
"The other magical girls you saw must have been doing something else, because no, I can't."
"Damn. Okay. Try blue highlights."
"That I can do, but they don't help much."
"Yeah...let's do something with your nails. Make them nice and regular and rounded, then--hm. Blue with silvery white opals, let's start out with."
"That's a little better."
"You need more jewelry. Try a filigree necklace in silver, with a centerpiece of blue opal and smaller seafoam opals trailing up to your shoulders."
"Now earrings--those will have to contrast more against the silver hair to be visible, so let's go with seafoam-anodized titanium with blue opals."
"Now we need to do shoes, you're still wearing your old ones. Let's start simple--kneehigh blue soft leather boots."
"Hm. Let's try something else--greek sandals with laces spiraling up to the knees? In silver."
