Chihaya is one of the heroines of Rewrite who suddenly transfers into Kotarou's high school. She is a clumsy girl who has trouble honestly showing her feelings and has led a sheltered life causing her to know little about the world. She is constantly arguing with Kotarou.
She is a summoner in Gaia, who has the strongest familiar ever created. Her supreme strength is a result of her contract with Sakuya, who is actually a familiar.
Her parents died when she was very young. After escaping this facility of some sort, she stood in front of a tree, helpless, and asked for help. As a result of that, one of the branches of the tree form the familiar called "Sakuya" who has been helping her ever since. They used to research familiars as researchers of Gaia. Her father left her a familiar, along with a note as he died.
Along the route, Chihaya quits Gaia and tries to become a normal girl, in which she succeeds.
