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.
as long as I have this...
...ما دمتُ أمتلِكُ هذا
Solange ich das hier habe,
¡Mientras tenga esto, podré recuperarlo!
¡Mientras tenga esto...
finché lui sarà nelle mie mani...
enquanto eu tiver isto...
