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.
and my songs will become a billion strengths,
،وتتحوّلُ أغانيي إلى قوّة مُضاعفة مليار مرّة
und meine Lieder werden
zu einer riesigen Kraft,
Mes chansons deviendront ma force
così come le mie canzoni
sarebbero mille volte più forti,
E minha canção vai se 
transformar em bilhões de forças
