This story begins with a phone call that was received at a particular young woman's home, in the middle of the night...
Please, Yuuko, open the door!
Bitte, Yuuko, öffne die Tür!
Te lo ruego, Yuko, ábreme por favor.
Te lo ruego, Yuko, 
ábreme, por favor.
Par pitié,
Ti prego, Yuuko, apri la porta!
Por favor, Yuuko, abra a porta!
