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!
It's not my fault.
لم يكن خطئي
Nicht meine Schuld.
No es culpa mía.
No es culpa mía.
Non è colpa mia.
A culpa não foi minha.
Я не виноват.
