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.
During episode 14 she ends up in an audition to be in a detective drama called Naughty detectives and chooses the boyish character role, ending up against Ichigo. The girls learn how dedicated Shion is to her roles and passes the audition, making her first friend: Aoi.
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.
Shion has a fair complexion with green eyes and dark brunette hair. Originally her hair reached mid-back, worn with a ribbon. After cutting it, it reaches her neck with the tips sticking up. She is normally found in a school uniform or the outfit of whatever role she's currently working on.
Shion started as a serious girl that was very dedicated to acting, trying out mostly for "cool" type parts. As the story continues, Shion opens up more, eventually being able to play the role of Alice and give a dazzling smile.
Kamiya (神谷) Kami (神) means god, possibly referring to her role as a genius actress and Ya (谷 tani) means valley.
