Kanako is a beautiful woman with long blond curly hair and pale white skin. She wears a long white coat with a green camisole top underneath and a short black skirt with black high heeled shoes. A necklace hangs around her neck and she wears rose colored lipstick. In the last three episode, she wears an altered colored version of her outfit, with her lab coat replaced with a mini jacket. She wears a pair of purple panties, which are exposed during her death.
She has been shown as an easy-going woman. She seems to know too much about the Elder Bairns but shows some sort of affection towards Saya.
PlotKanako is first seen when the bell rings for homeroom after Saya came to class. She said that they should watch the rest of Saya and the other's routine after lunch also stating that you need a straight man and a funny man causing the class to laugh. Then Tokizane comes to class, saying sorry for coming late but Kanako says that he doesn't really mean it. After he takes his seat, Kanako says that it was time to call attendance and called Saya when she said 'yes' Kanako said that she was just joking making the class laugh again. She is next seen coming to class and at that same time, Tokizane also cames to class. She tells him that he just barely made it and he apologizes. She says that his apologies just get him into more trouble.
The next day she is seen giving Saya punishment for coming to school late. Saya asks her if it was okay for her punishment to be helping with packing away the things from the chemistry lab but Kanako said that the school was easygoing so she had to be too. Saya then asks her ever since she's been a teacher has she been teaching at this school and Kanako replies with a yes. Saya then asks her if she ever did anything before becoming a teacher and Kanako says that she was a researcher before stating it was different from the chemistry she's doing now. Saya then asks her why she quit and she replied that their was certain things that you could only find out when you become a teacher.Kanako then asks Saya what she thought about school and she said it was fun but said that her father told her that she is a great deal unaware of something called common sense and asks if she causes problems for anyone else.Kanako quickly says that that wasn't possible because everyone liked her and then gets up from the table she was sitting on and walked up to Saya lifting her chin up and saying "I like you too" causing Saya to blush. She then backs away, telling Saya if anything bothered her to come and tell her leaving Saya stunned at what just happened.
The next time she is seen when Saya comes to class late the next morning. Saya apologizes but she said she'll let it slide because she wasn't done yet. She then looks out the window saying it's a nice day out and nothing's happening, leaving Saya shocked at what she just heard. Kanako continues, saying that she thinks it would be a nice peaceful day, leaving the class in total silence. In Episode 10, she asks Saya for viewing the books in the temple where Saya lives, only to show to Saya that all the books are new with empty pages, after Nono and Nene return, she asks Saya to end this joke. In the last episode, she was attacked by the Cerberus like Elder Bairn. She is almost killed and swallowed but is saved by Saya, after escaping it thanks to Saya, she ran from her in panic to the temple and asked Tadayoshi for help, he reveals to also be an Elder Bairn and bites her neck, drinking her blood before ultimately decapitating her.
She seems to hold some sort of affection for Saya, telling her that she liked her. In a later epsiode she gropes her (i.e. she lifts her skirt and touches her breast) ultimately however (specifcally after killing Cerberus) she comes to fear her.
They aren't shown to be together, rather she is only seen teaching them however in the later episodes they have formed an alliance to help Saya remember who she really is.
