Yuki, who was born in a world where sounds don't sound like anything, runs into the enigmatic Itsuomi and immediately takes an interest in him.
What language are they speaking behind me?
ما اللّغة الّتي يتحدّثونها خلفي؟
Die Leute hinter uns …
Welche Sprache sprechen sie wohl?
Je me demande quelle langue
parlent les gens derrière moi.
Chissà che lingua stanno parlando
 quelli dietro di me?
Que idioma estão falando
atrás de mim?
Какой язык звучит у меня за спиной?
คนข้างหลังเขาคุยภาษาอะไรกันอยู่นะ
