Saya Takagi from High School of the Dead

A young woman dressed in a green skirt and white blouse, with her hair styled in two long braids. She appears to be standing in front of a window or door, possibly in an indoor setting. The background is blurred, making it difficult to discern any other objects or details. However, the overall impression is that the woman is posing for a photograph or perhaps participating in some kind of performance or event.
