Sayaka Mizushiro
水城 さやか
A very rich girl who is Chihaya’s close friend. She can transform into Magical Warrior Cerulean Blue (with the help of her partner Hazuna) and takes the form of her idealized self (being more outspoken). She has a strong bond with Hazuna, so she is very powerful as a Magical Warrior, however, this consumes much of her physical strength, so she is weak in her civilian form.
