Mizushiro, Sayaka

水城さやか

A wealthy girl who is a close friend of Chihaya. With the assistance of her partner Hazuna, she transforms into Magical Warrior Cerulean Blue, assuming the persona of her idealized self, which is more outspoken. Her strong bond with Hazuna grants her significant power as a Magical Warrior; however, this drains much of her physical strength, leaving her weak in her civilian form.
