National Tournament Arc
Shiori first appears during a flashback of Teru's. While being invited to join the improvised team, she tells the girls that she is really weak but joins anyway. During her match she remembers Teru's instructions and defeats her opponent. Her team ends up winning the match.
After Teru walk out, Reika says that they must be close. However the girls tell her that they aren't and that it was simple advice that allowed them to win. Sometime later in the cafeteria, Shiori and the others seek out Teru and request something of her.
