The Ikeda Lab is, as is traditional, doing something for the university's Mutsumi Festival, an event which draws many people from off-campus. Yukimura proposes conducting a large-scale experiment on the importance of appearance for romance. He has readied a large number of cosplay costumes to rent out to visitors who will then participate in an attractiveness rating. In order to emphasize how important appearance is, Yukimura projects a series of images of Himuro in cosplay on the screen, including Himuro in a nurse's uniform, a maid's uniform, and a black cat style outfit?!
As an aside, from a biology standpoint, 
red is only effective on male humans.
.من ناحية بيولوجية، الأحمر يؤثر على الرجال البشر فقط
Aus biologischer Sicht hat allerdings das Rot
nur eine Wirkung auf männliche Exemplare.
Por cierto, biológicamente, solo
a los hombres les es atractivo el rojo.

Ce phénomène ne s’observe
Tra parentesi, da un punto di vista biologico, 
il rosso funziona solo sui maschi umani.
Aliás, biologicamente, vermelho só tem
efeito em humanos do sexo masculino.
Ну а с точки зрения биологии,
красный цвет влияет только на мужчин.
