Shion Kamiya is a student of Starlight School who debuted in Episode 14. She is an actress most of the time, and is a cool-type idol whose preferred brand is Futuring Girl. In Episode 38, Shion formed and is a member of the unit Powapowa-Puririn, along with Otome Arisugawa and Sakura Kitaoji.

Shion is a teenage actress who debuted at the age of 10. Known as the Actress of Seven Faces due to her ability to change expression upon the stage completely; going from serious to whichever personality she wants. Due to her serious nature always taking time for work, she didn't have any friends at first.

Shion is serious and contained, barely ever smiling or talking back before she befriended anyone. Despite this, she is not exactly unfriendly. She believes acting is everything and her passion for it knows no bounds. She will do what she can to feel more like the character she is trying out for, even if it means cutting off her hair. However, after she makes some friends Shion begins to smile and open up a lot more, though still she remains quite serious and maintains her cool composure.
