Kirika and Shirabe attempt to recover Dr. Ver so that he can treat their mom.  They run into Hibiki, whose fusion has progressed to the point where she can fight a Noise with her bare hands.  Dr. Ver injects them with a LiNKER boost, and they attempt to use their ultimate songs, which might kill them.
I'm sorry, Kiri-chan.
أنا آسفة يا كيري-تشان
Verzeih mir, Kiri.
Lo siento, Kiri-chan.
Lo siento, Kiri-chan.
Pardon, Kiri.
Scusami, Kiri-chan.
Desculpa, Kiri.
