Sayaka Miyata

Kaminashi's first friend and rival.

Before Keijo used to be a judo's athlete, she was the Japan's hope for a golden medal in the Olympics but threw it all away in the qualifications. She has a complex about her bust size and Kaminashi usually makes fun about it.

She previously resided in Room 309 before being promoted to the Elite Class. ~!Upon graduating from Setouchi, Sayaka officially becomes a B-Rank Keijo player, affiliated with the Kansai's Hyougo Branch.!~
