Sayaka Miki, Puella Magi Madoka Magica

A young girl with green hair and a blue dress standing in front of a window, looking outside. The girl has her left hand on the windowsill and is wearing a necklace with a pendant. She appears to be lost in thought, gazing out at something outside. The background of the image shows a room with white walls and a large window that lets in natural light. There are no other objects or people visible in the image.
