She's from CLAMP's Cardcaptor Sakura magical girl manga. Which incidentally is at it's 20th anniversary this year so there's some new merch and a continuation short set after the manga coming out, apparently. Her app is in her journal for you to read if you want.

But sure! If you beat me to getting a log up, link me and I can hit you up with her. I'm not sure if I'll manage to get a log up myself before like, Fri evening or the weekend because I'm busy with my course and work the next couple days.
