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.
As you speak to your mom through 
this, your voice will disappear.
.بينما تتحدّث إلى أمّك عبر هذه، سيختفي صوتك
Wenn du das verwendest,
dann verlierst du deine Stimme umso mehr,
Si le hablas a tu mamá
por medio de esto,
Plus tu vas parler à ta mère
en utilisant cet objet,
Man mano che parli a tua mamma 
attraverso questa, la tua voce sparirà.
Quanto mais você usar isso pra falar com
sua mãe, mais sua voz será roubada.
Поговорив с мамой через эту раковину,
ты полностью лишишься голоса.
