A 17-year-old member of "Undertaker" and the pilot for a humanoid robot known as "Endlave". She's usually in a wheelchair.
Not much is revealed about her past such as how she got her disability or why she follows Gai and work under the Funeral Parlor.
Ayase Shinomiya is created by Redjuice Graphics. In the New York Comic Con panel with the three producers of Guilty Crown, Oyama states that her tight body suit is derived from Neon Genesis Evangelion's suits. She first appears in episode 1. Her Japanese voice actress is Kana Hanazawa.
Ayase is a committed and strong-willed member of Funeral Parlor (Undertaker), and makes sure she follows her orders thoroughly. Towards Gai, Ayase tends to be soft-spoken, calm, and usually blushes when seeing him. Tsugumi usually teases Ayase about her apparent infatuation, and Ayase usually replies to Tsugumi's teasing with an angry and embarrassed tone.
Ayase does not like to be pitied due to her inability to walk and her use of a wheelchair. She refers to her wheelchair as "a part of her that makes her unique". Ayase built up a strong front, and doesn't like getting help from others. When she falls off of her wheelchair, she is determined to get back on by herself, but requests that nobody see her crawl on to it; saying that it goes against her "elegant" and "strong" image.
While training Shu, a bossy and mischievous side of Ayase was revealed. However, she manages to give Shu the confidence and guidance that he requires.
Ayase has long red hair, which she usually has up in a ponytail. Ayase has a pair of reddish-brown eyes.
Her Endlave suit is a tight body suit that is both red and grey in color.
It's seems that Ayase has a crush on Gai when she blushes after Gai compliments her for her efforts in holding back Daryl. She later reveals to Shu Ouma that she holds great respect for Gai.
She first appears in an Endlave during a battle on the bridge. Ayase assists Inori who gets caught by another mech. Later on, she fights Daryl Yan during Funeral Parlor's mission to save the inhabitants of Roppongi of being killed by GHQ. However, she loses to Daryl Yan.
Her weapon is piloting an Endlave despite having a disability.
