Hitoe is a very kind and shy girl. She becomes cold in the later part of Season 1 in order to fulfill her wish to become friends with Yuzuki and Ruko again although she has gotten back her gentle nature when her friends learned that she had regained her memories of their friendship.
Hitoe first appears in episode 2, where she challenges Akira Aoi to a battle. Despite thinking up some great strategies, she ends up losing due to a lack of confidence and resolve. During the match, Piruluk reveals that her wish is to make friends.
Though they come from different high schools, Hitoe and Rūko end up becoming friends. She is supportive in helping Ruko find Tama, though she is not afraid to scold her when she takes reckless actions.
