Nico is probably slightly insane, due to having moved an average of every three years for her entire life. If you ask her, "Where are you from?" she'll look at you in confusion for a moment, and then begin, "Well most recently . . ." Some day she'll stop moving.
No doubt also contributing to the madness, Nico reads too much (according to her mother, at least). She likes good fiction with a touch of the strange and non-fiction that combines science with folklore, but she also reads a lot of comics and watches too much anime.
Like many of her friends, she has been educated beyond the possibility of gainful employment (BA Archaeology, MA Folklore, BFA Writing) and is now trying to fix this by going to school again (this time a Bachelor of Design). Consequently, she is much older than her classmates, though no one seems to have noticed. You can see some of her school work (for an intro computer class) here.
