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.
You'd be the oldest brother,

Você é o irmão mais velho,
então diga alguma coisa!
Ты ведь самый старший, ну скажи ему!
