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.
Everyone in the other labs wears regular 
clothes, so we just wondered why.
جميع من في المختبرات الأخرى يرتدون ملابس عادية
 .لذا تساءلنا عن السبب فحسب
Es kam uns seltsam vor,
En los demás laboratorios visten ropa 
normal y nos preguntábamos el motivo.
Los demás laboratorios llevan
ropa de calle y nos extrañaba.
Il n’y a que chez vous
où les membres sont en blouse.
Mi chiedevo come mai, visto che
negli altri laboratori si vestono tutti normalmente.
É que o pessoal dos outros laboratórios
não usa, então achei curioso.
Сотрудники других лабораторий ходят
в повседневной одежде и без халатов...
