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.
The one that appears on rainy nights 
and tries to open the door.
الشيء الذي يظهر بالليالي الماطرة
.ويحاول فتح الباب
Das, was in verregneten Nächten
an meine Tür klöpft und sie versucht zu öffnen!
La que aparece en noches de lluvia
e intenta abrir la puerta.
La que aparece en noches de lluvia
e intenta abrir la puerta.
Le truc qui toque quand il pleut la nuit
et qui essaie d’ouvrir ma porte.
Appare solo nelle notti di pioggia
Aquela que aparece nas noites
de chuva e tenta abrir a porta.
Она стучится по ночам,
хочет отпереть дверь.
