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.
Hibiki... Hibiki!

Hibiki … Hibiki!
¡Hibiki... Hibiki!
¡Hibiki... Hibiki!
Hibiki !
Hibiki... Hibiki!
Hibiki... Hibiki!
