Mahou Sensou EP1 - Midsummer Magical Girl

One summer's day, Nanase Takeshi sees Aiba Mui, a girl in a school uniform he's never seen before, collapse outside the kendo clubroom at his school. Takeshi carries the unconscious Mui to the Nurse's Office to get her medical help, but upon waking, Mui takes him for a suspicious character with less-than-pure motives.
