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.
currently beyond your limits, to save me?

um mich zu retten?
superando vuestros límites para salvarme?!
oltre la vostra portata, per salvarmi?
que está além de seus 
limites para me salvar?
