Saku, Sosuke, and Uta try to figure out a way to make money so Saku can go on the school trip with them. They make a song but it doesn't seem to be getting enough attention, so Kakeru helps them make a PV for the song to help promote it.
This is my little sister!
!هذه أختي الصغيرة
Das ist meine kleine Schwester!
Ella es mi hermanita.
Esta é a minha irmã mais nova.
Ela não é bonitinha?
