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.
So is your song, Ka-chan.
!وأغنيتك كذلك أيضا يا كا-تشان
Dein Lied aber auch, Ka-chan.
-Você é demais, mesmo, Saku!
-Sua música também, Kachan!
