Ritsuka comes to the realization that he was so worked up at the concert that he kissed Mafuyu. Ritsuka hears that Mafuyu didn’t come to school because he had a fever, so he decides to go visit him. The next day, Mafuyu is feeling better and the band gets together to celebrate his recovery and to try to figure out their future as a band and figure out a name for their band.
and that's when they become
 a wave that hits your ear drums.
.عندها تصبح موجة تصطدم بطبلة أذنيك
Erst dann entsteht eine Welle,
die dein Trommelfell berührt.
así lanzarán la primera onda
que llegue a tus tímpanos.
Así lanzarán la primera onda
que llegue a tus tímpanos.
qu’il produit une onde de choc
et fait vibrer nos tympans.
è allora che il suono
e pela primeira vez elas se tornarão
ondas que atingem o tímpano.
А их первый звук поразит твой слух.
