Shiori Sakurazaka

Shiori is Jirou Yakuin's classmate and childhood friend (and crush). She was paired with Minami Tenjin in their school's couples training.

She is a kind and gentle girl, but she isn't very confident in herself and has a shy demeanor. Shiori is academically intelligent and regularly scores high marks on her exams, although she is known to struggle athletically. She is especially bad at talking to boys she doesn't know due to past experiences she had in middle school, but is known to be very caring towards those close to her regardless of gender, including Jirou and Mei. Despite the fact she is paired with Minami in the couples training, she seems to still harbor some feelings for Jirou.
