OVA 3: They'll See - The Far-Too-Stimulating Bodily Measurement Freezing : Season 1 Episode 15

The girls are having their body measurement check-up, where Rana shows her ability to correctly guess the breast size of the girls by groping them as she demonstrates it on Kaho, Ganessa, Satellizer, Chiffon and Ticy. Attia, who has an inferiority complex due to her smaller breasts, refuses to join until Chiffon decides to do the "examination" on her. Unknown to the girls, the boys are secretly listening from outside.
