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!
Th-This is our fault! It's because we went out
to karaoke in our school uniforms!
هـ-هذه غلطتنا! هذا لأنّنا ذهبنا
!للكاراوكي بأزيائنا المدرسيّة
D-Das ist alles unsere Schuld!
Es culpa nuestra.
¡No debimos venir con el uniforme!
Es culpa nuestra. ¡Nos pasa
por venir con el uniforme!
C’est notre faute.
On aurait pas dû venir en uniforme !
S-Siamo noi in torto!
A culpa é nossa.
Э-это наша ошибка! Зря мы пошли
 в караоке прямо в школьной форме!
