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!
This room is a sauna! 
Even my skin feels like it's being smothered!
!هذه الغرفة حارّةٌ جدّاً! أشعر حتّى باختناق بشرتي
In diesem Raum brutzelt’s!
Ich spür, wie meine Haut vertrocknet!
¡Hace demasiado calor aquí!
Me arde la piel.
¡Aquí nos vamos a asar!
Me arde la piel.
Trop chaud, même !
Notre peau peut pas respirer !
Questa stanza è un forno!
Persino la mia pelle sta soffocando!
Aqui é quente demais!
Até minha pele está sufocando!
Да здесь же баня! 
У меня даже кожа будто задыхается!
