Hibiki is badly shaken up after her meeting with her father.  She's so shaken up that even during the Autoscorer fight she can't focus properly, and Kirika and Shirabe have to protect her.
So sing next time!
لِذا غنِّي في المرّة المُقبِلة
Singt beim nächsten Mal.
Canten la próxima vez.
La próxima vez cantad.
La prochaine fois, chantez.
Cantate, la prossima volta.
Na próxima, vão ter que cantar.
