Marisa Kirisame calls herself a magician, but she's really just an ordinary human who uses magic, thus giving her the title "Ordinary Magician." She is a relatively informal person who has a thing for collecting thing, so much so that she steals things, most notably from the library of the Scarlet Devil Mansion, but she doesn't call it stealing, she calls it borrowing. Her best friend (and enemy) is Reimu.
Gensokyo is like feudal Japan, so there's no phones or stuff like that.
