Turns out, her name is Hana, and she's a pixie exchange student from Japan. She'll be attending school in Colorado for a while, and she needed a place to live. Syrinx (unbeknownst to me) had put an ad for a roommate in the Pixie Pages, and so Hana contacted her.
They seem to get along really well.
When she's not at school, or cleaning or cooking, Hana mostly hangs out in her room, working on her laptop, and watching DVDs. She seems to be a bit of a horror movie fan.
Personally, I think Syri spends too much time talking to people on the web (being that it's part of her job and all) and not enough talking to people in person. I think having a roommate is just about the best thing that could've happened to her.
Welcome to the family, Hana!
