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 ruin whatever I'm doing!
وتُفسِدن ما أفعله
und spuckst mir in die Suppe!
y estropeas todo lo que hago!
e rovini qualunque cosa io faccia!
E arruína tudo o que faço!
