Also known as: 砂狼白子(骑行), シロコ(ライディング)
Official Alternate Costume for Shiroko (Blue Archive).
Shiroko forgoes her school uniform and replaces it with a white and blue Bike Jersey with Abydos High School cycling team marking around it, from which she's the only member (so far) in the group. She also includes her trademark cross-shaped hair ornament and green biking gloves in this costume. She also brought a large bag that you can also see in her swimsuit costume.
