Oozora Subaru wearing a yellow shirt and shorts HD Phone Wallpaper

Oozora Subaru, a young woman with short brown hair and blue eyes, smiles and makes a peace sign with her right hand. She is wearing a yellow and white striped t-shirt tied at the waist, white shorts, and knee-high socks. A stopwatch hangs from a necklace around her neck. She stands outdoors with buildings and a cloudy sky in the background.
