The principal has found an interesting video on NewTube. She has Rika and Haruo listen to it. Haruo decides that since the singers are more "yes" than "no," he needs to find them and add them to the choir. But the choir will have to catch them first!
If we lose, we won't bother you anymore.
إن خسرنا، فلن نضايقكم بعد الآن
Wenn wir verlieren,
lassen wir euch in Ruhe.
Si perdemos, no los molestaremos más.
Si perdemos, no os molestaremos más.
Si on perd,
j’arrête de vous importuner.
Se perderemo noi, non vi disturberemo più!
Se nós perdermos, não nos metemos mais.
Если мы проиграем, 
то трогать вас не будем.
