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.
Nothing to be done for it.

No hay remedio.
Qué le vamos a hacer.
C’est la vie.
Non possiamo farci nulla.
Não há nada que possa ser feito.
