Himeno and Nozomi have come to Kyoko's house for a study meeting. As they're working, something strange happens...
Everyone else covers themselves 
when they change, you know?
الجميع يغطون أنفسهم عندما
يغيرون ملابسهم، صحيح؟
Ihr bedeckt euch doch auch
alle beim Umziehen, oder?
Todos se cubren cuando se cambian, ¿no?
Todo el mundo
se cubre al cambiarse, ¿no?
Quand on se change,
tout le monde se cache.
E poi, anche tutte le altre
si coprono quando si cambiano.
Todo mundo se cobre quando se troca, sabe?
Все ведь прикрываются, 
когда переодеваются.
