Nausicaa's new to Sunnydale. Like, starts school tomorrow new. New foster family, old friends are gonna be a pain to keep in contact with especially with how bad Nausicaa is at writing...
But new place means new friends, and a new city to explore! Her foster mom'd said something about here being dangerous, but Nausicaa's been a street kid before, and is decently confident in her ability to handle herself. Plus, she won't stay out past sundown.
...Or that's her intention, anyways.
It's getting properly dark when she acknowledges she just might be slightly lost.
