At the Okinawa training camp, Yukimura and Himuro shared a kiss of the highest theoretical value on a bridge of the greatest mood value under the beautiful, painterly rays of the morning sun. But the amount of saliva they collected was insufficient and so retesting is required. They head to the biological sciences' Regulation of Biological Systems Department to meet with a specialist in saliva testing. There, they find an alluring woman dressed like a traditional courtesan wearing a lab coat, Suiu, and her sweetheart, Chris. When Yukimura asks Suiu and Chris to help with their experiment to "give proof of love," Chris and Suiu flaunt their overwhelming aura of love.
That's true. We don't often enter onto 
the grounds of other departments.
.هذا صحيح. في العادة لا ندخل الأقسام الأخرى
Allerdings. Sonst betreten wir nur selten
das Territorium der anderen Fakultäten.
Es verdad, uno no suele 
ir a otras facultades.
Es cierto que no se suelen visitar
el resto de facultades.
Moi non plus, je ne visite pas souvent
les autres départements.
È vero. Di rado entriamo
nelle aree degli altri dipartimenti.
Да, мы и в самом деле очень
редко ходим на другие факультеты.
