Shaia Hishizaki (菱崎 シャイア, Hishizaki Shaia) is a character from Voltage Fighter Gowcaizer. Her official nickname is The Daydreaming Galactic Policewoman. She is themed after double life fantastical slice of life manga and the character archetype of the school wide popular aspiring idol.
Shaia is a member of the 3rd attack force unit in the 78th Observing Police Investigation Unit of the Space Federal Direction Control Agency. Known as being "sunny" with her peers, their group's goal is to protect and monitor the peace of the local natives of each planet. To investigate the troubling news from planet Earth, Shaia is ordered to infiltrate the location of their last known coordinates, Bernar High School. Apparently, the information they need is top secret and ranked S Level on the importance scale.
In her culture, Shaia's people only use numbers to distinguish themselves from one another and there is no psychological difference between either member. Upon her arrival on earth, she quickly makes her pseudonym, Shaia Hishizaki, based on the Hishizaki melon bread she ate from her earth friends. With the courage of "Miss Bernard", she is determined to win victory in an exploding fashion. With Ball Boy and her unit's uniform, she poses as the Shaia Mask unit to deliver justice.
At the school, Shaia is considered a very popular idol with the male students. She releases CDs of her songs and likes to take photo shoots. In her ending, she wins but is greeted by her old rival, Rosary. The two ladies fight for the spotlight and glory.
Shaia is a fiercely independent woman who is fickle about what she likes. She doesn't take her duties as a policewoman too seriously and wants to live an enjoyable life of glamor and fame.
