Sumireko looks after Oto while Adashino is away. They go to Oto's school where Sumireko revels in the joys of youth. She and Oto run into Uname and spend the evening with her. But their peace is short-lived as the shadow of a new Curiosity draws near.
I can't allow crass thoughts 
to cross my mind.
لا يجدر بي السماح للأفكار البذيئة
.أن تخطر ببالي
Unanständige Gedanken
muss ich unterbinden.
Debo alejar de mí los deseos carnales.
Debo alejar de mí los deseos carnales.
Je ne peux pas penser
à de telles choses.
Non posso permettermi di pensare queste cose.
Não devo permitir pensamentos
grosseiros em minha cabeça.
Надо отбросить грязные мыслишки!
ฉันไม่ควรให้ความคิดที่หยาบคาย
เข้ามาในใจของฉัน.
