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.
I've told you not to expose so much 
skin when you're first meeting people!
!أخبرتك ألا تعرضي جسدك عندما تلتقين بأشخاص لأول مرة
Du sollst doch beim ersten Treffen
mit Fremden nicht so viel Haut zeigen!
¡Te he dicho que no muestres 
tanto a gente que recién conoces!
¡Estoy harto de decirte que enseñes
menos carne ante los desconocidos!
Ne t’expose pas comme ça
devant nos invités !
Ti avevo detto di non mostrare così tanta pelle
quando devi incontrare qualcuno per la prima volta!
Eu já falei para não ficar se expondo
para desconhecidos!
Я же просил тебя не оголяться так
при первой встрече!
