Sora

She wears a white sailor uniform with a charcoal collar and rolled-up sleeves, a red ascot held in place by a silver pin, and a matching gray skirt with a white stripe running down the hem. The collar, cuffs, and skirt of her uniform are decorated with a criss-cross checkered pattern. She also wears white socks that are slit just below the knee, and black Mary Janes.

Her AI has three large scars resembling animal scratches, revealed in Chapter 5. Her character design sheet reveals that this was based on the injury Akane received after saving Rei Mekaru. However, the only thing that remained in her memory was the word "Sora", and so she decided to call herself Sora until she eventually remembered everything.
