A third-year high school student and the bassist of the band SSGIRLS. She is Yori's best friend. Aki is a peppy girl with a carefree attitude. She always manages to keep her band in a positive mindset and enjoys teasing them. Although, on the inside, she is quite self-conscious about her past and current relationships. Aki desperately does not want to lose anyone like she had lost Shiho, but she keeps these feelings bottled up, and only rants to Yori when requested. She cares about her friends deeply and is the one who selflessly got Himari to hook up with Yori despite her feelings for the latter.

Birthday: April 12th

Blood type: B
