It's time for the choir to start rehearsing in earnest, but the AC is broken and it's too hot to think. They move to somewhere cooler, and Rika gives them a song to hone their rhythm. Then, they're swept up in a series of inexplicable events!
Keeping your guard up like that, 
you must be thirsty.
لا بدّ أنّك تشعر بالعطش
من الحفاظ على انتباهك هكذا
Von der ganzen Anspannung
hast du sicher Durst.
Con tantos nervios
seguro que tienes sed.
Con tantos nervios
seguro que tienes sed.
Vous devez avoir soif,
à force de crier.
on tutta questa tensione,
ti sarà venuta una gran sete, no?
Deve dar sede de ficar alerta assim.
У вас, должно быть, во рту пересохло
от этой нервотрёпки.
