Kanao was an indecisive and quiet girl due to the abuse she endured in her past before meeting the Kocho sisters. She became unable to make decisions by herself and repressed her emotions as a defense mechanism. In order to help rectify this, Kanae Kocho gave her a coin to flip to decide which path to follow when she didn't know what to do. She also gains the ability to speak unambiguously and Kanao gradually becomes able to express her emotions.
