Yukako Yamagishi, JoJo's Bizarre Adventure, Diamond is Unbreakable

The image depicts Yukako Yamagishi from JoJo's Bizarre Adventure: Diamond is Unbreakable, standing in what appears to be an interior hallway or lobby. The woman has long brown hair and wears a blue sailor-style school uniform with pink accents on the collar, sleeves, and tie. She holds her left hand up near her head and faces slightly toward the viewer while looking over her right shoulder. Her expression is neutral, but there may be a hint of concern in her eyes. The woman's legs are positioned as if she is walking forward, and she wears white socks with black shoes. The background consists mainly of an off-white wall with thin vertical stripes running across it. A large mirror hangs on the right side of the wall, reflecting other objects that may or may not be part of the scene. There are no other people visible in the image. It is likely a cosplay photo taken during a convention.
