Tsukihi Araragi from Monogatari Series HD Wallpaper

A young girl with short black hair and a white flower accessory in her hair, wearing a green kimono with white floral patterns and a yellow obi, sits on the floor. She has a surprised expression with her mouth open. In the background, there are abstract orange and white shapes, and a red object hangs from above. A small yellow mound with several sticks is in the foreground.
