Rio learns that his mother's ears have turned into pot stickers because his older brother Yuu was kidnapped, and Rio feels responsible for what happened. When Rio nearly falls off a cliff while searching for Yuu, Ramune throws himself in harm's way to protect him and ends up badly injured. In order to save Ramune, Rio uses the Pearl of Night Voices he received from Ramune to treat his mother, desperately calling out to his mother, who can't hear his voice.
But that's only if there's 
nothing on the scale.
.لكن ذلك فقط إلّم يكن هناك شيء في كفّة الميزان
Das ist aber nur der Fall, wenn nichts riskiert
und in die Waagschale gelegt wird.
Pero eso es cuando no hay
nada más sobre la balanza.
Enfin, c’est le cas de figure
où on ne met rien dans la balance.
Ma solo se non c'è nulla 
sull'altro piatto della bilancia.
Mas isso só no caso de
não haver nada na balança.
Но это только в том случае,
когда ничего не стоит на кону.
