Cobalt, Chrom, Kei, and Neon are androids living together in an abandoned house. In order to pay off a huge electrical bill, the four decide to compete for prize money at the Babel entertainment tower. After their first performance, they meet Esora, a boy struggling with the recent loss of his father. The encounter activates a special program within the four androids.
I see. We can all sing one song together.
فهمت، يمكننا غناء أغنيةٍ واحدة معاً
Ich verstehe.
Wir sollen gemeinsam ein Lied singen.
Comprendo. Todos cantaremos
la misma canción.
Comprendo. Todos cantaremos
la misma canción.
Oh, d’accord.
Tu veux qu’on chante tous ensemble.
Capisco. Vuoi che cantiamo
 la stessa canzone insieme.
Faz sentido. Todos nós podemos
cantar uma música juntos.
Ясно. Мы можем петь одну песню вместе.
