Kanako Sumiyoshi

Kanako Sumiyoshi is one of Junpei Kōsaka's classmates/childhood friend. Kanako is a quick-tempered, confident, forthright and outspoken person. She harbors romantic feelings for Junpei Kōsaka (Kanako's friend) yet she is afraid to admit this to him as she sees that he has a crush on Kaede Mizuno. Kanako thinks of the other girls as obstacles standing in the way of his love. She gets angry easily and she seems to not be on good terms with Nagi Ichinose because they fight in the pool over her touching her chest. She is a good friend of Mizuno's and always feels guilty whenever she spends time Junpei due to the fact that Mizuno has a crush on Junpei.
