Kazusa is the second eldest of the Sugimoto sisters.     She is a gentle woman who people gravitate to because of her sweet nature and affability, though as Yasuko notes, she is a very rough and grounded person. She knows that both her sisters loved her boyfriend. She jokingly though piercingly and truthfully says that she took Kagami for her own and would never give him up to either one of them.    Out of all the sisters, she seems to be the least eccentric and blunt though unlike the rest of them, when she does speak her mind, her words are harsh and borderline cruel because of her honesty.     She once was a colleague of Yamashina Hinako and Kagami, as she was an art teacher in Fujugaya. 

Fumi and Akira were close childhood friends until Fumi had to move away. Ten years after losing touch with each other, the two girls meet again as high school freshmen. The two struggle to reconnect after so much has changed, and both deal with the trials and tribulations of high school &mdash; sometimes independently and sometimes with each other&rsquo;s help.

Fumi and Akira were best friends when they were little, with Akira always looking after the crybaby Fumi, but that all ended when Fumi's family moved away. Several years later, Fumi's family returned, and she and Akira happened to bump into each other on their way to school. They became friends again, quickly slipping back into old patterns. Shortly after, Fumi began dating a cool, attractive upperclassman who, coincidentally enough, had ties to Akira's current school, the prestigious Fujigaya Girls' Academy.
